Description
D12FPH Series
DIN Rail High Power Fiber Optic Sen sors
Printed in USA 06/08 P/N 34970 rev. C
D12s have a 15-turn SENSITIVITY control, with a
slotted brass screw clutched at both ends of travel.
D12FPH Series sensors may be used with either the
small diameter (.020") or large diameter (.040") Ban-
ner cut-to-length plastic fibers.
See page 4 for sensor dimension drawings. D12 Sen-
sors mount directly to a standard DIN rail. They may
also be through-hole mounted to a surface using the
supplied bracket (see page 4) and stainless steel M3
x 0,5 mounting hardware.
D12s are constructed of rugged black ABS (Cyco-
lac
®
KJB). The transparent housing cover is acrylic.
D12FPH Series sensors are rated NEMA 2.
WARNING
D12FPH Series sensors 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.
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.
Only MINI-SCREEN ® , MULTI-SCREEN ® , MICRO-SCREEN ™ , 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.

D12 Features
(top panel shown)
Very high power sensors for use with plastic fiber optic assemblies
D12FPH Series sensors are compact, totally self-contained visible-red fiber
optic sensors for DIN rail mounting. D12FPH Series sensors are designed for
use with Banner cut-to-length plastic fiber optic assemblies. They may be used
in the opposed and diffuse fiber optic sensing modes. D12FPH Series sensors
have the highest optical power available in a plastic fiber optic sensor.
D12s operate from 10-30V dc and draw 45 mA maximum, exclusive of load
current. Models are available with a choice of NPN or PNP complementary
outputs (one output normally open, one output normally closed). The normally
closed output of all models may be used as a diagnostic alarm output, depending
upon the hookup of the sensor to the power supply*. All models are available
with either an attached cable or a 6" pigtail with a pico-style quick disconnect
connector. A complete listing of models is given on page 2.
Each output is capable of 150 mA continuous load. The choice of NPN (sinking)
or PNP (sourcing) models enables D12 sensors to interface to a wide variety
of loads.
Two top-mounted LED indicators (see drawing, right) light to indicate POWER
ON
and NORMALLY OPEN OUTPUT CONDUCTING conditions.
A highly-visible red 7-segment moving-dot LED bargraph † (right) lights to in-
dicate the relative strength of the received light signal. This feature can greatly
simplify sensitivity adjustment and the task of fiber optic alignment, as well as
provide a constant reference over time for overall sensing system performance.
Also, segment #1 of the bargraph flashes to indicate an output overload, and
segment #7 flashes to indicate marginal excess gain. A flashing LED corresponds
to the "on" state of the D12’s alarm output.
