GENERAL DESCRIPTION
These miniature self-contained and powerful Retroreflective, Proximity
(Diffuse) and Opposed Beam Pair Photo-electric sensors provide
application flexibility in counting, positioning and object detection. Their
small size, in addition to various mounting options, greatly increases
alignment ease and application possibilities.
All units can be powered by supplies ranging from +10 to +30 VDC
and are reverse polarity protected. Green and amber LED’s display
operating status from 360 degrees, indicating “power on” and “light
sensed”. You can tell operating status of your sensors at a glance.
MODEL RRDC2 ‐ RETROREFLECTIVE SENSOR
The Model RRDC2 is a miniature, DC powered, retroreflective photoelectric sensor. The “visible” LED light beam allows for easy alignment
and is modulated, to provide immunity to ambient light. The small beam
size makes it a good choice for detecting relatively small objects.
In operation, the visible LED light beam is directed at a retro reflective
target. An object breaking this beam will trigger the output.
RRDC2
RETROREFLECTIVE
MODELS EMDC2 & RCDC2 ‐ OPPOSED BEAM EMITTER/ RECEIVER SENSOR PAIR
SENSING RANGE UP TO 21' (6.5 M)
The Models EMDC2 (Emitter) and the RCDC2 (Receiver) are
miniature, DC powered, Opposed Beam photo-electric sensor pairs with
a 66 foot sensing range. The Emitter contains a high power modulated
“infrared” LED. The Receiver contains a sensitive photo-transistor and
output transistor.
In operation, the output will turn on when the Receiver detects that an
object has broken the Emitter beam. Due to their high gain, they are
ideally suited for detecting opaque objects in dirty and dusty areas or
when condensation or oil film environments are present.
OBJECT
MODEL PRDC2 ‐ PROXIMITY SENSOR
The Model PRDC2 is a miniature, DC powered, Proximity (Diffuse)
photo-electric sensor with a 18" maximum detecting distance. This
sensor requires no special reflectors or reflective tapes and the limited
sensing range reduces detection of background reflections. It is ideally
suited for detection of transparent or translucent objects, parts ejected
from presses, and rotating targets such as pulley spokes. A modulated
“infrared” LED light beam provides immunity to ambient light.
In operation, the modulated light beam is reflected by the detected
object. This reflected light beam is sensed by a photo-transistor, which in
turn energizes the output. Actual sensing range is determined by the
surface area and the amount of reflectivity of the object.

SAFETY SUMMARY
SPECIFICATIONS
All safety related regulations, local codes and instructions that appear
in this literature or on equipment must be observed to ensure personal
safety and to prevent damage to either the instrument or equipment
connected to it. If equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be impaired.
Do not use this unit to directly command motors, valves, or other
actuators not equipped with safeguards. To do so can be potentially
harmful to persons or equipment in the event of a fault to the unit. An
independent and redundant temperature limit indicator with alarm outputs
is strongly recommended.

The unit features an extremely simple
method for setting sensitivity (gain). Reduce
gain by turning the pot counter-clockwise. If the
gain is set too low, turn the pot clockwise to the
appropriate level. Gain may be readjusted in
this way at any time.
