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 Delrin

Proximity detection is the detection of an object in a given range.  That detection range of the RPS-400-30 can be controlled by a resistor or potentiometer wired to the green and black leads of the unit, and is adjustable to the desired detect distance.  Any object within the desired range is detected, while objects  outside the desired range are ignored.  The detect point is independent of size, material, or reflectivity.  The proximity option is denoted by the part number RPS-400-30.

The RPS-400-30 can be furnished with Hysteresis Control capability. The Hysteresis sensor has a fixed detect point equal to the sensors minimum range and an adjustable turn off point up to the sensors maximum range. Simply stated, an object will be detected at the minimum range, and will remain detected until the object is no longer within the adjustable turn off point. (See figure above). the Hysteresis option is denoted by the part number RPS-400H-30.
