About the RPS-150 Sensor

The RPS-150 family of self-contained, wide beam angle, ultrasonic sensors can be used as proximity sensors or level sensors. The advantage of this sensor is that the target does not have to be at right angles with the sensor in order to be detected. A flat target can tilt up to 35 degrees and still be detected. For set-up purposes an LED indicator is provided. When in the non-detect state the LED is Green and when in the detect state the LED is Red. The RPS-150 can be operated in two modes: a proximity and a hysteresis mode, described to the right.

The frequency of operation is 38.5kHz. There are two ranges available in this model: 2″ to 40″ or 5″ to 80″. The sensor is available with a 120VAC power input or a 20 – 30VDC input.It also features a quick disconnect receptacle. The housing is constructed of plastic valox and has standard 30mm X 60mm limit switch mounting dimensions, as well as side holes for mounting the sensor on its side. The output consists of two solid state relays N.O. N.C., and can switch 2 – 130VAC or VDC up to 100mA DC or 50mA AC continuous. The relay outputs are short circuit protected and isolated up to 1500 volts rms.
