Mining

In mining applications, BEI Sensors helps with everything from shaft elevator
control and ore cart positioning to the control of heavy equipment such as
excavators and earthmovers. Sensors in this environment have to withstand
high shock and vibration, along with extremely dusty and wet conditions. BEI
manufactures rugged products designed to deliver optimum performance in
these demanding operations. In addition, when hazardous area certifications
are required, BEI Sensors offers a number of products certified by UL,
CENELEC, LCIE and MSHA rating agencies.

Metal Manufacturing

There are few harsher, more corrosive environments than a steel
mill. Molten steel is cast into large slabs at blistering temperatures.
Water from line sprayers hits freshly poured slabs, creating clouds
of steam. Every piece of equipment is exposed to continuous
humidity. BEI speed and position sensors are engineered to
withstand this unforgiving environment. Encoders are available with
stainless steel housings and other protective coatings to prevent
corrosion and rust. High IP ratings are offered to resist pressurized
spray, condensation, and dust. BEI Sensors’ products are built tough
to operate reliably in these severe conditions.

Oil and Gas

Sensors used in the oil and gas industry must withstand high temperature
and pressure, potentially explosive locations, and extreme shock and vibration,
along with exposure to chemicals, dirt and moisture. Position sensors perform
crucial functions in oil and gas applications and must operate reliably day in
and day out to ensure an optimized yield. BEI Sensors is well aware of these
unique upstream, midstream, and downstream requirements and has designed
products that feature uncompromising quality and performance. Hard anodized
housings, gross leak tests, extended temperature ranges and a variety of
sealing options are available on numerous BEI products. BEI Sensors also offers
one of the largest selection of hazardous area rated products, including UL
Class I Division 1 and 2, and Class II Division 1 and 2, and ATEX Zone 1 and
Zone 2 (See page 9). A variety of communication protocols including Profibus,
CANopen and DeviceNet are also offered.

Choosing the Right Sensor Technology

BEI offers a variety of speed and position sensing technologies. It’s important to choose one that’s suited to
your particular application. The sensor’s operating environment, required degree of precision, output type,
speed, and physical configuration all must be considered. The descriptions of the different technologies on
these pages will help guide you in choosing the optimal speed and position sensing technology.

Optical Technology

RATINGS ON FIVE KEY CRITERIA

Ruggedness

PRecision

sPeed

TemPeRaTuRe

emi ResisTance

Optical sensing technology uses the interruption of light to
detect movement. Optical encoders have an internal code disc
with opaque lines or patterns that are rotated in the path of a
light source, typically from an LED. The code disc acts like a
shutter to alternately block (OFF) or unblock (ON) the light to an
internal photodetector. The photodetector senses the alternating
light beam, which the encoder’s electronics convert into an

electrical signal. This signal is passed to an external control
system through the encoder’s output.

Optical sensing technology is the most precise and offers
the highest resolution of the position sensing technologies.
It is also resistant to environmental magnetic interference
and, when enclosed in a metal housing, highly resistant to
EMI. BEI Sensors’ optical encoders are well sealed, allowing
them to operate in harsh and dirty environments. They are
also highly resistive to shock and vibration, and are capable
of withstanding a 50 g, 11 msec shock pulse and 20 g’s of
vibration (5 to 2000 Hz). This level of robustness makes BEI
encoders well-suited for most industrial applications.

BEI optical encoders are ideal for numerous types of
industrial processes, such as oil well drilling, machine control,
agricultural machinery, web process control, robotics, elevators,
construction equipment, cranes, motor feedback and any
closed loop control systems.

Magnetic / Hall Effect Technology

RATINGS ON FIVE KEY CRITERIA

Ruggedness

PRecision

sPeed

TemPeRaTuRe

emi ResisTance

Magnetic sensing technology uses changes in magnetic fields
to detect movement. There are two ways magnetic technology
is integrated into the BEI Sensors offerings, digital encoders and

analog Hall effect position sensors. Magnetic encoders use a
disc that has been magnetized with multiple, north/south pole
pairs that are in the form of radial lines or patterns. In place of
a photodetector, magnetic encoders use an ASIC designed to
detect alternating north and south poles as the disc is rotated
past it. As the ASIC senses the change in magnetic poles,
internal electronics convert it into a digital electrical signal that
is then passed through the device’s output.

In the Hall effect sensor configuration, the internal disc is
magnetized with a single pole pair. The disc is attached to
the sensor’s rotor which is then coupled to the motion being
measured. The sensor’s ASIC is designed to detect the change
in the direction of the magnetic field as the disc rotates above

it. These changes in magnetic field are converted to an analog
signal that is ratiometric (proportional) to the angle of the
rotating disc.

Hall effect sensors are typically used to resolve angular position
with an analog output while magnetic encoders are most often
used to detect rotational speed and direction with a digital
output. Magnetic encoders tend to have lower resolution
and precision than their optical counterparts and are more
susceptible to environmental magnetic interference. However

Potentiometric Technology

RATINGS ON FIVE KEY CRITERIA

Ruggedness

PRecision

sPeed

TemPeRaTuRe

emi ResisTance

Potentiometric sensing technology is available in one of three
configurations: wirewound, conductive plastic and hybrid.

Wirewound potentiometers are comprised of a resistive element
(coil) and a contact spring (wiper).The coil is made from a very
fine wire that is precisely wound onto a mandrel. The wiper, a
specially engineered precious metal contact, wipes across the
wound coil. The coil is fixed internally to the sensor’s housing
and the wiper is attached to the sensor’s rotor which in turn is
coupled to the motion being measured. A voltage is applied
across the coil and the coil becomes a voltage divider. As the
motion being measured rotates the wiper across the energized
coil, a voltage proportional to the rotational position can be read
between the coil and the wiper. The output changes in discrete
steps as the wiper moves across the individual coil windings.

Conductive plastic potentiometers are very similar to wirewound,
except that the wiper moves across a conductive plastic
element rather than a coil. The conductive plastic element is
comprised of a substrate and a resistive epoxy. In its pre-cured
state this resistive epoxy material is referred to as “ink”. The ink
is applied to a substrate using a silk screening process. Once

both products are ideal for operation in very high temperatures
and environments with extreme shock.

Ideal applications for magnetic encoders include wind energy,
tree harvesting, traction motors for rail equipment and
pavement profiling. Hall effect sensors excel in steering,
pedal and throttle for off-road equipment, dancer controls in
web processing, flow control valves and elevator door opener
applications.

cured, the ink acts very similarly to the coil in a wirewound
potentiometer, with the advantage of having a very uniform,
smooth surface. This surface provides a more continuous output
and longer life as compared to a wirewound potentiometer.

As its name implies, hybrid potentiometers use a combination of
the two previous mentioned configurations, using a wirewound
coil coated with the conductive plastic material.

Wirewound potentiometers provide the highest accuracy of the
three configurations and dissipate power very well; however
because of the metal-to-metal contact between the wiper and
coil, wirewounds have a shorter operating life. Conductive
plastic potentiometers provide the highest resolution or output
smoothness and have a higher operational life than wirewounds,
however it is more difficult to get the high linearity (accuracy)
available from a standard wirewound potentiometer. Hybrid
potentiometers are able to combine the best aspects of both
other configurations. A hybrid potentiometer has a better
ability to dissipate power (over conductive plastic pots) and has
improved resolution or output smoothness (similar to conductive
plastic potentiometers). The use of conductive plastic material
gives hybrids a longer operating life over wirewounds.

Potentiometers in general have several benefits including
small package size and weight, resistant to electromagnetic
interference (EMI), temperature stability and are able to work at
very high (300C max) and low (-55°C) operating temperatures.

Ideal applications include aircraft control surfaces, in-cylinder
hydraulics and oil field downhole measuring.

BEI understands the challenges posed by extreme environments and has developed an extensive line of
products designed to operate in the harshest conditions imaginable. The icons below each represent a
particular environmental extreme. They are used in the product selection pages of this guide (pages 8–25) as
a quick visual indicator of which products are designed to operate in which extreme environment condition

.

Wet If a sensor has to operate in a liquid environment, it must have adequate sealing and the appropriate IP rating (as

a measure of ingress protection) to guard against contamination. Products rated IPX5 are protected from “water jet” liquid
ingress. An IPX6 rating indicates protection from “powerful water jets.” An IPX7 rating means the product can be immersed
in water up to 1 meter for 30 second durations. BEI products with this icon are rated IPX6 or above.

Dirty/Dusty

operate in the constant presence of dust. The majority of BEI products are rated to this level and this icon represents this
rating. Products with the lower IP5X rating are considered as only “dust protected,” which means that dust ingress is still
possible. IP5X rated products are recommended for environments where dust is only occasionally present.

Extended Temperatures

temperature range—typically 0 to +70°C. If your application requires operation in extreme temperatures (above or below
these ranges), BEI offers extended temperature options. Products with this icon have extended temperature ratings (beyond
their stated operating temperature) as a standard option.

High Shaft Load

sensors or potentiometers. Encoders have internal bearing structures that can carry some load. In applications that use
gears or drive belts, excessive radial (side) loading of the shaft can shorten bearing life. Encoders should be specified in
accordance with the anticipated radial loading. Typical maximum loads for industrial encoders are 5 to 40 lbs (22 to 178 N).
Ultra heavy-duty encoders are available to withstand heavier loads. Encoders with this icon can withstand high shaft loads
in the range of 40 to 300 lbs (178 to 1335 N). See individual product data sheets to determine actual maximum load.

Corrosive or Washdown

a corrosive environment. In food or medical-grade applications, where washdown may occur, an electroless nickel coating
or stainless steel housing is recommended. Products with this icon incorporate special finishes or housing material as a
standard option.

Hazardous Areas

potentially explosive environments. Products with this icon have certification for one of the following: explosion-proof, flame
proof, intrinsically safe, or non-incendive. Refer to the next page for complete information on hazardous area certifications.

BEI Sensors offers a complete selection of UL and ATEX certified position sensing products. Certifications
include UL Class I Division 1 and 2, and Class II Division 1 and 2, as well as ATEX Zone 1 and Zone 2. The
tables on this page provide details on BEI Sensors products’ certifications. A variety of protection methods
are available. The four most common are described below.

Explosion Proof Construction

• Enclosure can withstand internal ignition and contain the

explosion without damage to the enclosure

• Heated gases from an explosion that pass through gaps or

joints in the assembly will be cooled sufficiently to not ignite
gases outside the housing

• Must be connected using gas-tight conduit

• Rated for Division 1 or Zone 1 installations

Flame Proof Construction

• Enclosure can withstand internal ignition of volatile

gas-to-air mixtures without damage to the enclosure

• Allows for termination using a certified cable gland

and cable

• Cannot be used for Division 1 hazardous areas

Intrinsic Safety

• Limits the maximum energy that can be delivered into the hazardous

location

• Has limitations on the amount of energy that can be stored within the

body of the device

•

Ensures that even in double fault condition, not enough energy is sup-

plied to or stored in the encoder which could create a spark or heated
surface to ignite gas, vapor, dust or fiber in the hazardous area

•

Must be used with Intrinsically Safe (IS) barrier. An IS encoder installed
without an IS barrier is not an IS system.

Nonincendive

• Assures no sparking or hot surfaces will occur in the device under

normal operating conditions (unlike intrinsically safe encoders which
are evaluated under fault conditions)

•

Acceptable in Division 2 and Zone 2 installations where explosive

agents are present only in abnormal operating conditions

Shock and Vibration

The use of position sensors in high shock or vibration environments that are
not properly rated can result in output errors, reduced accuracy, or component failure. It is important to be aware of an
application’s expected shock and vibration and select a sensor rated for that environment. Products with this icon can
withstand greater than 100 g’s of shock or over 10 g’s of vibration. See individual product data sheets for maximum shock
and vibration ratings.

This is a versatile interface between
an incremental encoder and any
receiving electronics. It accepts
single ended or differential inputs
and provides single ended or
differential outputs in either an open
collector or line driver configuration.

It accommodates all standard
operating voltages from 5 to 28 VDC. Up to eight Optical Isolator
Modules can be daisy-chained to provide multiple, simultaneous
outputs to controllers or PLC’s. This Optical Isolator can help clean

for applications where a different resolution output is needed

SwiftComm™ Wireless Sensor Interface Extensive Product Adaptability

A Secure, Robust Wireless Interface with Built-in Reliability

Necessary for Real-Time Industrial Control

With the BEI SwiftComm wireless industrial sensor interface the
machine designer is free to install sensor equipment without the
expense and constraints of a hard-wired system. Installations
in difficult applications like cranes, rotating tables or mobile
applications, are greatly simplified.

The SwiftComm system includes the transmitter-receiver pair,
which communicates using a point-to-point frequency-hopping

2.4 GHz RF protocol. Because of its flexible input/output
electronics, it can interface with many different industrial
sensors and control systems. Simply connect the SwiftComm
transmitter to the sensor and the SwiftComm receiver to your
control system and apply power. That’s it. No complicated
cabling is required.

SwiftComm’s proprietary radio protocols include a broad security
code range, data encryption, handshaking, interference recovery,
and error checking. Ruggedness and flexibility are further
enhanced with SwiftComm’s NEMA 4 weatherproof enclosures,
panel mounting options, antenna choices and wide-range DC
power inputs. SwiftComm is available with an incremental or SSI
output, or with an optional explosion proof transmitter housing.

Robust Signal

BEI’s SwiftComm operates on the 2.4 GHz ISM radio band and
uses Adaptive Frequency Hopping Protocol (AFH). This helps
avoid data interruptions due to frequency interference. If a
particular radio channel encounters interference, SwiftComm
seamlessly hops to another open channel. To enhance RF link
reliability even more, when SwiftComm detects interference on
a channel, that channel is dropped from the hop sequence. If
the available channels list ever becomes exhausted, previous
dropped channels are retested to see if they are clear.

SwiftComm’s patent pending technology can even overcome
data loss due to link interruption. Internally and transparent to
the user, SwiftComm keeps track of the sensor’s output signal.
If SwiftComm encounters packet loss from temporary link
interruption, it fills in output information based on the historical
data trend and processes this information in place of the lost
packet. SwiftComm corrects for any accumulated error and
seamlessly sends the corrected data to the controller. Even in
environments where occasional packets are lost, SwiftComm
will transmit a continuous stream of data to the control system

Real Time Control

It is critical in any motion control application to have minimum
lag time in signal transmission. SwiftComm is one of the
fastest wireless sensor interfaces available. Data is relayed
between the transmitter and receiver every 600 microseconds
(µs). Because SwiftComm is a point-to-point configuration,
there is minimal latency.

Secure Transmission

SwiftComm provides a very secure system for data to travel
wirelessly. The transmitter and receiver each have a 40-bit
hard coded security code. These codes are programmed at the
factory and give the system a range of over 500 billion possible
unique codes. BEI has developed its own proprietary protocol
for SwiftComm, which is not available to the public. Additionally,
the data is transmitted with a high-level encryption algorithm
and pseudo-random frequency hopping. This provides additional
levels of data security to assure that your data is protected.

Long Range

Because motion control applications can vary widely, SwiftComm
has a 50 mW radio for reliable long-range communication. In
most open situations, a reliable link distance of up to 1,000 feet
is possible. Inside buildings, a reliable link distance on the order
of 300 feet can be expected.

.

BEI Sensors’ exhaustive experience and capabilities in design, engineering and manufacturing allow us

to provide innovative adapted products and complete custom solutions to meet unique position sensor

requirements. For decades we have provided thousands of modifications to all our standard products. From

customizations as simple as adding a connector or changing a shaft size to merging parts of two standard

products, BEI takes pride in its ability to adapt to any customer’s product needs.

Other adaptations require more significant changes, such as the modification of a product’s size and

shape so that it will fit into a particular package design. Complete customization, where the technology

itself is adapted to meet a customer’s requirements, is also fully within BEI’s capabilities. Our experienced

engineering team works closely with customers to help specify their requirements, outline a design, develop

prototypes, and—after final customer approval—move the custom sensor into production.

BEI Sensors has the ability and willingness to make these types of modifications, ensuring that you will

receive a position sensor configured to your specifications, allowing drop-in installation and simplifying

production and assembly at your facility. If you are not finding exactly what you need in this catalog, just ask

and we will be happy to create a customized solution with you.
