RPS-401/RPS-426 Ultrasonic Proximity Sensor Description
The RPS-401 and RPS-426 are self-contained ultrasonic sensors in a 30mm barrel housing, powered by 20-30VDC. A sealed transducer provides protection in hostile environments. The sensor can be operated in two modes a proximity and a hysteresis mode. Operating as proximity sensors and level sensors. The frequency of operation for the RPS-401 is 212kHz for the 4″ to 40″ range and 150kHz for the 8″ to 80″range. The RPS-426 has an 8″ to 80″ range, and operates at a frequency of 150kHz. These sensors also have built-in short circuit protection for the outputs as well as reverse polarity protection on the input.

The construction of the RPS-401 sensor is PVC plastic and the RPS-426 is Stainless Steel. A barrel housing is used 30mm in diameter by 100mm in length. For set up purposes an LED indicator is provided. When not detecting the LED will illuminate green and when detecting the LED will illuminate red. The outputs consist of two solid state relays N.O. and N.C. which 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. A standard 6′ cable is provided or a quick disconnect (QD) version is also available.
