BEI Sensors HS45 User Manual

HS45 Incremental Optical Encoder

The HS45 is a large bore, heavy duty, rugged
encoder designed to operate in very demanding
environments. It is available in both single and dual
output versions as shown above. These encoders
use a preloaded bearing set for mechanical stability
and a long service life.
The dual output version has redundant electron ics
internal to the encoder simplifying signal distribution
to multiple controllers.

Special Models of the HS45 Incremental Encoder are available with one or more of the
following certifications. Consult factory for details.

Notes

1. The typical hollow shaft product is supported by, and clamped to, the driving shaft. A

flexible tether is used to keep the housing from rotating.

2. The rubber shaft seal is recommended in virtually all installations. The most common
exceptions are applications requiring a very low starting torque or those requiring opera­tion at both high temperature and high speed. For these exceptions, a felt shaft seal
is recommended. Felt seals require very low starting torque and can virtually eliminate
frictional heat. Encoders ordered with felt shaft seals will have an enclosure rating of
IP50 and will have less than 1/10th the Starting Torque specified under Mechanical
Configurations.

3. Non-standard index widths and multiple indices are available by special order. Consult
factory.

4. Complementary outputs are recommended for use with line driver type (source/sink)
outputs. When used with differential receivers, this combination provides a high degree
of noise immunity.

5. Output IC’s: Output IC’s are available as either Line Driver (LD) or NPN Open
Collector (OC) types. Open Collectors require pull-up resistors, resulting in higher output
source impedance (sink impedance is similar to that of line drivers). In general, use of a
Line Driver style output is recommended. Line Drivers source or sink current and their
lower impedance mean better noise immunity and faster switching times. Warning: Do
not connect any line driver outputs directly to circuit common/OV, which may damage
the driver. Unused outputs should be isolated and left floating. Our applications special­ists would be pleased to discuss your system requirements and the compatibility of your
receiving electronics with Line Driver type outputs.

28V/V: Multi-voltage Line Driver (7272*): 100 mA source/sink. Input voltage 5 to 28
VDC +/- 5% standard (Note: V
5 volt supply. Supply lines are protected against overvoltage to 60 volts and reverse
voltage. Outputs are short circuit protected for one minute. Supply current is 120 mA
typical (plus load current). This is the recommended replacement for 3904R and 7406R
open collector outputs with internal pullup resistors. It is also a direct replacement for
any 4469, 88C30, 8830 or 26LS31 line driver

28V/5: Multi-voltage Line Driver (7272*): 100 mA source/sink. Input voltage 5 to 28 VDC
+/- 5% standard, internally regulated with 5V (TTL compatible) logic out. Supply lines are
protected against overvoltage to 60 volts and reverse voltage. Outputs are short circuit pro­tected for one minute. Supply current is 90 mA typical (plus load current).

28V/OC: NPN Open Collector (3904*, 7273*). Current sink of 80 mA max. Current
sourced by external pull- up resistor. Output can be pulled up to voltage other than
supply voltage (30 V max). Input voltage 5 to 28 VDC
is 120 mA typical. This replaces prior IC’s with designations of 3904, 7406, 3302, 681
and 689. 5V/OCR, 15V/OCR, 24V/OCR: Open Collector (3904R*, 7406R*, 7273R*):
Current sink of 70 mA max. Includes internal pull-ups sized at approximately 100
ohms/volt. Max current source is 10 mA. Supply current is 100 mA typical, 120 mA
with internal pull-ups. The 5V/OCR, 15V/OCR and 24V/OCR are often replaced by the
28V/V in system upgrades.

3904, 3904R, 4469, 5V/V, 5V/OC, 5V/OCR, 9V/OC: Intrinsically safe line driver and
open collector outputs. These drivers are specific to intrinsically safe encoders, and are
installed per the appropriate control drawings listed in Table 2.1 on page 48.

6. Special –S at the end of the model number is used to define a variety of non-standard
features such as special shaft lengths, voltage options, or special testing. Please consult
the factory to discuss your special requirements.

7. Higher frequency response may be available. Please consult with the factory.

8. Extended temperature ratings are available in the following ranges:

-40 to 70°C, -40 to 85°C, –20 to 105°C and –40 to 105°C depending on the particu­lar model. Some models can operate down to -55°C. Extended temperature ranges can
affect other performance factors. Consult with factory for more specific information.

9. Mating straight plug receptacles may be ordered from the factory:
For M12 use MS3116F12-10S, For M14 use MS3106F14S-6S

For M14/19 use MS3116J14-19S, For M16 use MS3106F16S-1S
For M18 use MS3106F18-1S, For M20 use MS3106F20-29S
