Red Lion Controls RCDC0000 DC RECEIVER(OPPOSED BEAM)

DescriptionThe Models EMDC (Emitter) and the RCDC (Receiver) are compact, DC powered, Opposed Beam photo-electric sensor pairs with a 10 foot sensing range. The Emitter contains a high power modulated “infrared” LED. The Receiver contains a sensitive photo-transistor, amplifier-demodulator and output transistors. In operation, these outputs will be triggered when the Receiver detects that an object begins to break 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. The small 1/8' well defined beam size allows for sensing small parts accurately and provides repeatable edge sensing of opaque objects to better than 0. 01' for accurate positioning applications. Greater accuracies can be achieved by aperturing the Emitter, Receiver or both. However, aperturing will result in reduced sensing distances. While the beam size is small, the Receiver has a wide field of view which allows easy “line-of-sight” alignment.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.
