Self Contained Sensing Range 5 - 30” Narrow Sensing Beam High Frequency 222kHz Operates in Hostile Environments Operating Voltage 12 - 30VDC NPN Transistor Output Externally Adjustable Sensing Range The RPS-400-30 has a 22mm barrel housing, completely self-contained, 12 - 30VDC powered ultrasonic proximity sensor. A sealed transducer provides protection in environments where dirt and moisture are a problem. The sensor is constructed of Acetal plastic with a silicon rubber sensing face. This sensor is range or distance sensitive, enabling the sensor to detect objects only within the desired range, and reject objects outside the desired range. The RPS-400-30 is a solid state sensor and has an NPN open collector transistor output. For initial setup purposes, a built in LED indicator illuminates when the ultrasonic wave from the sensor is reflected back to the unit within the desired range. The sensing range is fixed or adjustable. By connecting a fixed resistor or adjustable potentiometer between the green lead and black lead of the cable the maximum range can be set from 5 to 30 inches. The resistor chart on the following page provides resistance values and the approximate resulting sensing range. These sensors provide precise proximity or level sensing regardless of color, density or transparency. They are equally effective on liquid, metal, plastic and glass targets. A standard 6 foot cable is provided. Call factory for optional cable lengths. Adjustable Detect Point Proximity Detection Proximity detection is the detection of an object at a given distance. The detection range of the RPS-400-30 is controlled by a fixed resistor or adjustable potentiometer connected to the green and black leads of the sensor. Any object within the desired range is detected, while objects out of range are ignored. The range of the RPS-400-30 can be adjusted from 5 - 30". If the green lead is connected directly to the black lead the range will be set to less than 5".
