D12s are compact, totally self-contained visible-red fiber optic sensors
for DIN rail mounting. D12 sensors are designed for use with Banner
glass and cut-to-length plastic fiber optics. Standard D12FP and D12FV
plastic and glass fiber optic sensors offer fast 0.5 millisecond (500 s)
response. D12FVY Series (page 3) and D12FPY Series (page 4) sensors
have switch-selectable 50 s/500 s response modes for applications that
require a faster, high speed response time (50 s as compared to the 500
selectable response times along with a built-in 20 millisecond pulse
stretcher for use with loads (or input circuits) that are too slow to react to
quick sensing events when using the 50 s response mode.
All models operate from 10-30V dc. D12s are available with a choice
of NPN or PNP complementary outputs (one output normally open, one
output normally closed). The normally closed output of FP and FV
models (only) 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-type quick
disconnect connector. There is one D12 model line for glass fibers, and
another for plastic fibers. Model listings are given on pages 3 and 4.
Plastic fiber models may be used with either the small diameter (.010"
and .020") or large diameter (.040") Banner cut-to-length plastic fibers.

received light signal. This feature can greatly sim-
plify sensitivity adjustment and the task of fiber optic
alignment, as well as provide a constant reference
over time for overall sensing system performance. In
all models and in both response modes, segment #1 of
the bargraph flashes to indicate an output overload.
On all sensors operating in the 500 s response mode,
segment #7 flashes to indicate marginal excess gain.
On standard (FP and FY) models, a flashing LED
corresponds to the "on" state of the D12's alarm output.
D12s have a 15-turn SENSITIVITY control, with a
slotted brass screw clutched at both ends of travel.
D12s are constructed of rugged black ABS (Cycolac
KJB). The transparent housing cover is acrylic. All
D12 sensors are rated NEMA 4.
