Description
About the RPS-401A Sensor
The RPS-401A analog ultrasonic sensors are enclosed in a PVC barrel housing and are completely self contained. They are powered by 20 – 30VDC and are reverse polarity protected. The sensors have a narrow beam angle which enables them to get into tight places. A flat target can tilt up to 8 degrees and still be detected. The RPS-401A have two short circuit protected analog outputs, 4 – 20mA and 0 – 10VDC. These outputs can easily be inverted and scaled over almost any range by means of adjusting the near point P1 and far point P2. For setup purposes a LED strength indicator is provided. The LED is green when not detecting a target. The color can vary from yellow to bright red when detecting a target depending on how strong the reflected signal is from the target. Yellow indicates a weak signal and bright red indicates a strong signal. The transducer frequency for the RPS-401A is 175kHz for the 4 – 40″ range and 150kHz for the 8 – 80″ range. The RPS-401A housing is constructed of PVC plastic. See the RPS-426A data sheet for the Stainless Steel version. The housing measures 30 mm x 104 mm. A standard 6′ cable is provided, or a quick disconnect (QD) version is also available.

The RPS-426A 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-401A data sheet for the PVC plastic version. The housing measures 30 mm x 104 mm. A standard 6′ cable is provided, or a quick disconnect (QD) version is also available.
