Sensing range: see individual excess gain curves, pages 3 and 4.
Sensing beam: visible red, 680 nanometers.
Supply voltage: 10 to 30V dc at 45 mA max, exclusive of load.
Protected against reverse polarity and inductive load transients.

The N.C. (normally closed) output of standard FP and FV models may
be used as an alarm output, depending upon the hookup to the power
supply.
Output rating: Complementary outputs, one normally open (N.O.)
and the other normally closed (N.C.). 150 mA maximum each output.
No false pulse on power-up. (False pulse protection circuit causes a 0.1
second delay on power-up.) Short-circuit protected.
Off-state leakage current <10 microamps at 30V dc.
On-state saturation voltage <1V at 10 mA dc; <1.5V at 150 mA dc.
The total load may not exceed 150 mA.
Response time (FV, FP models): .
500 microseconds "on"; 500 microseconds "off".
Repeatability is 130 microseconds.
FVY, FVY1, FPY, and FPY1 models have switch-selectable standard
500 microsecond response mode plus a high speed (50 microseconds
on/off) mode. Repeatability in the high-speed (50µs) mode is 15 mi-
croseconds. FPY1 and FVY1 models (when used in the 50µs response
mode) include a 20 ms pulse stretcher for use in applications in which
the load (or input circuit) requires a longer input signal.
Response time and repeatability are independent of signal strength.

Indicators: Two top-mounted LED indicators, one yellow and one
green, and one seven segment red LED moving-dot bargraph. Note
that the seven segment bargraph and marginal excess gain indication
(bargraph segment #7) are inoperative in the 50µs response mode on
Y and Y1 models.
GREEN LED lights for DC POWER ON.
YELLOW LED lights for NORMALLY OPEN OUTPUT CONDUCT-
ING.
On all models in 500µs response mode, the 7-segment moving dot
red LED bargraph lights to indicate relative received light signal
strength. On all models in 50 and 500µs response modes, segment
#1 ashes to indicate OUTPUT OVERLOAD. On all models in the
500µs response mode, segment #7 ashes to indicate MARGINAL
EXCESS GAIN. On standard FV and FP models, a ashing LED
corresponds to the "on" state of the alarm output. (Alarm output not
available on Ys & Y1s.)
Adjustments: All models have a SENSITIVITY control on top of
module (15-turn slotted brass screw, clutched at both ends of adjust-
ment). FVY and FPY (high speed models) also have a top-mounted
response mode selector switch.
Construction: Black ABS (Cycolac

KJB) housing with acrylic
cover. Rated NEMA 2; IEC IP11. The ber clamping element is

. Stainless steel M3 x 0,5 hardware for use with mounting
bracket (supplied).
Cable: 6-1/2-foot (2 m) or 30-foot (9 m) attached PVC-covered
cable, or 6-inch pigtail with pico-type
4-pin QD connector.
Mounting bracket: D12 Series sensors mount directly to a stan-
dard DIN rail, or may be through-hole mounted using the supplied
mounting bracket and M3 x 0,5 hardware. Bracket material is black

Operating temperature range: -20° to +70°C (-5° to +158°F).
Maximum relative humidity 90% at 50°C (non-condensing).
Application caution...
D12 Series sensors are designed to deliver very high optical energy
(excess gain). They should not be used for applications which offer
low optical contrast (i.e. only a small difference in received light levels
between the light and dark sensing conditions). Examples include diffuse
mode sensing of objects in front of a reective background and opposed
mode sensing of non-opaque materials.
D12 sensors excel in applications requiring high excess gain (e.g. for
long-range sensing, sensing with long ber lengths, diffuse sensing of
materials with low reectivity, etc.)
