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).

Light/dark operate selection is done at pin #3.
For light operate mode, leave pin #3 unconnected.
For dark operate, connect pin #3 to +V dc.

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.
