Description

About the RPS-401 Sensor

The RPS-401 ultrasonic proximity sensors are enclosed in a PVC barrel housing and are completely self-contained. They are powered by 20-30VDC and have reverse polarity protection. A sealed transducer provides protection in hostile environments. The sensor can be operated in two modes, proximity mode or hysteresis mode, as described below. The transducer frequency is 175kHz for the 4 to 40″ range and 150kHz for the 8 to 80″ range. The outputs consist of two solid state relays configured as N.O. and N.C. which can switch 2-130VAC or VDC up to 50mAAC or 100mADC continuous. The relay outputs are short circuit protected and isolated up to 1500 Volts RMS. The RPS-401 housing is constructed of PVC plastic. See the RPS-426 data sheet for the Stainless Steel version. The housing measures 30 mm in diameter by 104 mm in length. For set up purposes an LED indicator is provided. The LED will illuminate green when nothing is detected and will illuminate red when a target is detected. A standard 6′ cable is provided or a quick disconnect (QD) version is also available.

The relay outputs are short circuit protected and isolated up to 1500 Volts RMS. The RPS-426 housing is constructed of Stainless Steel and is able to with withstand higher temperatures than the PVC version(there is an up-charge for this housing). See the RPS-401 data sheet for the PVC plastic version. The housing measures 30 mm in diameter by 104 mm in length. For set up purposes an LED indicator is provided. The LED will illuminate green when nothing is detected and will illuminate red when a target is detected. A standard 6′ cable is provided or a quick disconnect (QD) version is also available.
