These are compact visible-red fiber optic sensing modules for PC-board mounting. PC44 modules are designed for use with all .040" core diameter Banner cut-to-length plastic fiber optic assemblies.
PC44s operate from 10-30V dc and draw 25 mA maximum, exclusive of load current. Model PC44BN6FP has one NPN (sinking) load output and one NPN (sinking) alarm output. The PC44BP6FP has one PNP (sourcing) load output and one PNP (sourcing) alarm output. The load output is selectable for light- or dark-operate. Alarm outputs are normally open, and conduct whenever module excess sensing gain falls below 1.5x in the light condition.
Load outputs and alarm outputs are each capable of 100 mA, continuous load, except when both outputs are used. When the alarm output is used, the total combined load (both outputs) may

not exceed 100 mA. PC44 modules can interface to a wide variety of loads.
Two top-mounted LED indicators light to indicate POWER ON, OUTPUT OVERLOAD, ALIGNMENT, and EXCESS GAIN 1 to
1.5x (LOW GAIN) conditions. The LOW GAIN indication corre­sponds to the "on" state of the module's alarm output.
Fiber optic assemblies are available as either coiled or straight fibers, bifurcated or individual, and with a variety of sensing end styles (see page 4). Representative sensing range and beam pattern informa­tion for the opposed and diffuse sensing modes is given on page 3.
PC44s may be soldered directly to a printed circuit board. Also, a kit of closed-end jacks is available (model PCJ-25; see specifi­cations) to allow the PC44 module to plug into a printed circuit board. PC44 modules also plug into standard I/O mounting racks.
Specifications and model listings, PC44 modules:
Sensing range: opposed and diffuse sensing modes; see curves, page 3. Sensing beam: visible red, 680 nanometers. Supply voltage: 10 to 30V dc at 25 mA maximum, exclusive of load,
at module pins #2 (+Vdc) and #5 (dc common). 10% maximum ripple.
Module model listing and output configurations:
Solid-state dc outputs, selectable for light- or dark-operate:
PC44BN6FP = NPN sinking load output plus NPN sinking alarm output. PC44BP6FP = PNP sourcing load output plus PNP sourcing alarm output.
Light operate/dark operate mode selection for the load output (mod-
ule pin #4) is done by either connecting or not connecting module pin #3 to +V dc (see page 2).
Light operate mode: Normally open load output conducts when the receiver sees the emitter's modulated visible red light.
Dark operate mode: Normally open load output conducts when the receiver does not see the emitter's modulated light.
The alarm output (at module pin #1) is normally open (N.O.), and conducts whenever the excess gain in the light condition falls below 1.5x.
Module output rating: 100 mA maximum each output.
No false pulse on power-up. (False pulse protection circuit causes a 100 millisecond delay on power-up.) Short-circuit protected.
Off-state leakage current <1 microamp at 30V dc. On-state saturation voltage <1V at 10 mA dc; <1.5V at 100 mA dc.
When the alarm output is used, the total load may not exceed 100 mA.
Response time: 1 millisecond "on"; 1 millisecond "off".
Printed in USA
Repeatability is 0.25 milliseconds.
Response time and repeatability are independent of signal strength.
Indicators: Two top-mounted LED indicators, one yellow and one
green. Indications are as follows:
GREEN glowing steadily = dc power "on". GREEN flashing = output overloaded. YELLOW glowing steadily = excess gain in light condition is >1.5x. YELLOW flashing = excess gain in light condition is marginal (<1.5x).
Flashing YELLOW corresponds to a conducting (closed) alarm output.
Adjustments: Single-turn SENSITIVITY control on top of module. Construction: Polypropylene
pins. Completely sealed, epoxy-encapsulated circuitry. Plated steel mounting (hold-down) screw.
Mounting: Three options are possible.
1) PC44 modules may be soldered directly to a printed circuit board.
2) A set of socket pins is available for PC board mounting. Socket pin kit (model PCJ-25) contains 25 socket pins (5 pins are
required per module) and 5 hold-down nuts (1 required per module).
3) PC44 modules plug into standard I/O mounting racks. Contact Banner's applications engineering department for further informa-
tion.
Operating temperature range: -20° to +55°C (-4° to 131°F). Maximum relative humidity: 90% at 50°C (non-condensing).

Fiber Installation
Gripper door
(Lift up here)
Fiber Installation Procedure:
1) Cut fiber to length as described in the data sheet accompanying the fiber.
2) Gently lift up the edge of the gripper door along the "label side" of the module.
3) Push both fibers into the proper ports* until they stop. While holding the fibers snugly in place, press the gripper door closed.
*Ports are labeled for emitter and receiver fibers. The difference is not important when bifurcated fibers are used in the diffuse mode, but may be a factor when individual fibers are used (opposed sensing mode). The emitter port is for the fiber on the emitter side of the process; the receiver port is for the fiber on the receiver side of the process.
WARNING PC44 Series modules do NOT include the self-checking redundant circuitry necessary to allow their use in
personnel safety applications. A sensor failure or malfunction can result in either an energized or a de-energized sensor output condition.
!
Only MACHINE-GUARD and PERIMETER-GUARD Systems, and other systems so designated, are designed to meet OSHA and ANSI machine safety standards for point-of-operation guarding devices. No other Banner sensors or controls are designed to meet these standards, and they must NOT be used as sensing devices for personnel protection.
2
Never use these products as sensing devices for personnel protection. Their use as safety devices may create an unsafe condition which could lead to serious injury or death.

In opposed mode sensing, emitter and receiver fiber optics are set up opposite (and facing) each other, and the object to be detected passes between the fiber optic sensing tips and breaks the light beam. Two individual (PI Series) fiber optic assem­blies are required: one to carry the emitted light and the other to carry the received light. The curves (above left) show typical opposed mode performance of a PC44 module fitted with two PIT46U fibers in the opposed sensing mode.
Opposed mode sensing range may be extended by using lenses on both emitter and receiver fibers. The curves (above right) show the typical performance of PIT46U fibers fitted with L2 lenses. L2RA (right-angled) prisms may be used with threaded­tip fibers to provide sensing at right angles to the fiber tips, although at somewhat reduced sensing range compared to unlensed fibers.

Standard models of PI Series individual plastic fiber optic assemblies are included in the list at the bottom of page 4. Banner Engineering Corp. can custom-design plastic fibers to suit the requirements of your particular application. Contact one
of our application engineers by telephone or FAX for a quote on your design.
Diffuse fiber optic sensing mode
Diffuse mode sensing utilizes bifurcated (PB Series) fibers. These are paired fibers, one of which carries the light from the emitter element to the sensing point, while the other carries the light (reflected from the sensed object) from the sensing point back to the receiver element.
The curves (right) show typical performance of a PC44 module fitted with a model PBT46U fiber assembly in the diffuse sensing mode. Diffuse mode sensing range is referenced to a white test card of 90% reflectance. Less reflective objects will shorten the sensing range.

Banner Plastic fiber optic assemblies
Banner plastic fiber optics are an economical alternative to glass
fiber optics for piping photoelectric sensing light into and out of confined areas where the environmental conditions allow.
They are offered in two general styles: individual and bifurcated. Individual (PI Series) fibers are used in pairs in the opposed sensing mode. One fiber transmits the light to the sensing location, while the other fiber returns the received light to the sensor.
Bifurcated (PB Series) plastic fiber assemblies are "two-way" fibers having a single sensing end that both emits and receives light and dual control (sensor) ends which attach separately to the sensor. Plastic fiber optic assemblies are available in a variety of sensing end styles. Coiled assemblies may be used successfully on reciprocating mechanisms for millions of cycles.
Banner plastic fiber optic assemblies are available in two monofila­ment core diameters: .020-inch and .040-inch. PC44 Series
modules require .040-inch core fibers.
Banner standard plastic fiber optic assemblies are unterminated on the control (sensor) end. Fiber assemblies are approximately 6 feet (2m) in length. They can be used "as-is", or they may be cut to a shorter length. Each assembly is supplied with a cutting device to allow the fiber to be easily cut to length. Cutting instructions are included with the fiber assembly.
Due to their light transmission properties, plastic fiber optics are recommended for use only with visible light fiber optic sensors.
Banner Engineering can custom design plastic fibers to suit your application requirements. Contact one of our application engi-
neers by telephone or FAX for a quote on your particular design.
Specifications, Banner plastic fiber optic assemblies
SENSING RANGE: refer to the excess gain curves for the fiber optic sensor
to be used. The selection charts at the front of the Banner product catalog list all self-contained fiberoptic sensors and page references for gain curves.
TEMPERATURE EXTREMES: temperatures below -30° C will cause embrittlement of the plastic materials but will not cause transmission loss. Temperatures above +70° C will cause both transmission loss and fiber shrinkage.
REPEAT BENDING/FLEXING: life expectancy of plastic fiber optic cable is in excess of one million cycles at bend radii of no less than the minimum (stated below) and a bend of 90 degrees or less. Avoid stress at the point where the cable enters the sensor ("control end") and at the sensing end tip. Coiled plastic fiberoptic assemblies are recommended for any application requiring reciprocating fiber motion.
OPERATING TEMPERATURE: -30 to +70° C (-20 to +158° F). CHEMICAL RESISTANCE: the acrylic core of the monofilament optical
fiber will be damaged by contact with acids, strong bases (alkalis) and solvents. The polyethylene jacket will protect the fiber from most chemical environ­ments. However, materials may migrate through the jacket with long term exposure. Samples of fiber optic material are available from Banner for testing and evaluation.
MINIMUM BEND RADIUS: 1.0 inch (25mm) for .040 inch diameter fibers. CONSTRUCTION:
OPTICAL FIBER: plastic monofilament PROTECTIVE JACKET: black polyethylene THREADED END TIPS and HARDWARE: nickel-plated brass PROBE END TIPS: annealed (bendable) T304 stainless steel ANGLED END TIPS: hardened T304 stainless steel FERRULED END TIPS: T303 stainless steel
