Additional Description

Description

The Model PRDC is a compact, DC powered, Proximity (Diffuse) photo-electric sensor with a 12' maximum detecting distance (as measured with a 90% reflective white test card). This sensor requires no special reflectors or reflective tapes and the limited 12' 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 object to be detected. Actual sensing range is determined by the surface area and the amount of reflectivity of the object. This reflected light is sensed by a photo-transistor, amplified, demodulated and then energizes the outputs.

The sensor provides application flexibility in counting, positioning and object detection. The unit is interchangeable with conventional 18 mm threaded barrel-type photo-electrics and inductive proximity sensors. The small 2-1/8' x 1-1/4' x 1/2' size, in addition to various mounting options, greatly increases alignment ease and application possibilities.

The unit can be powered from +10 to +30 VDC and is reverse polarity protected. Current sinking NPN and current sourcing PNP Open Collector Transistors are protected from continuous overload and inductive load transients and are rated to 150 mA, with low saturation voltage and less than 1 µA offstate leakage current. In addition, no false outputs are generated at power-up. A 6 foot long 4 conductor PVC jacketed cable with strain relief provides supply input and transistor outputs.

A gasketed removable back cover provides access to the LIGHT/DARK Operate Mode Selector. When in the “Light Operate” (LO) position, outputs turn on when light is received by the detector. When in the “Dark Operate” (DO) position, the outputs are turned on when sensor light is not detected. Also accessible is a 15-turn screwdriver adjustable GAIN potentiometer that enables precise adjustment of system sensitivity. A rear mounted LED Signal Strength Indicator “lights” whenever the sensor sees a light condition and “blinks” at a rate proportional to the received signals strength (the stronger the signal, the faster the rate). This LED allows for easy alignment and monitoring of signal strength deterioration due to dirty optics or changes in alignment.
