About the RPS-400-30 Sensor

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 silicone rubber sensing face. This sensor is range or distance sensitive, enabling the sensor to detect objects 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 waveform is reflected back to the unit within the preset 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 ranges can be set from 5 to 30 inches. The resistor chart, on the data sheet, provides resistor values and the approximate resulting sensing ranges.

The ultrasonic sensor can be used as a proximity sensor or level sensor. It is equally effective on liquid, metal, plastic and glass targets regardless of color, density, or transparency. Standard 6ft. cable is provided. Optional cable lines are available.
