Instruction Manual
D12s are compact, totally self-contained visible-red ber optic sensors
for DIN rail mounting. D12 sensors are designed for use with Banner
glass and cut-to-length plastic ber optics. Standard D12FP and D12FV
plastic and glass ber optic sensors offer fast 0.5 millisecond (500 µs)
response. D12FVY Series (page 3) and D12FPY Series (page 4) sen-
sors have switch-selectable 50µs/500µs response modes for applications
that require a faster, high speed response time (50 µs as compared to the
500 µs of FP and FV models). D12FVY1 and D12FPY1 models have
switch-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 50µs 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 bers, and another for
plastic bers. Model listings are given on pages 3 and 4.
Plastic ber models may be used with either the small diameter (.010" and
.020") or large diameter (.040") Banner cut-to-length plastic bers.
Two top-mounted LED indicators (see drawing, right) light to indicate
POWER ON and NORMALLY OPEN OUTPUT CONDUCTING condi-
tions.
On all D12 sensors operating in the 500µs (standard)
response mode, a red seven-segment moving-dot LED
bargraph (below) lights to indicate the relative strength
of the received light signal. This feature can greatly
simplify sensitivity adjustment and the task of ber
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 ashes to indicate an output overload. On all
sensors operating in the 500µs response mode, segment
#7 ashes to indicate marginal excess gain. On standard
(FP and FY) models, a ashing 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 2.

WARNING These photoelectric presence 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 a safety device may create an unsafe condition which could lead to
serious injury or death.
