The RPS-401A analog ultrasonic sensor is mounted in a barrel housing and is completely self contained. It is powered by 20 – 30VDC and is reverse polarity protected. It also has a narrow beam angle which enables it to get into tight places. A flat target can tilt up to 8 degrees and still be detected. The RPS-401A has 2 short circuit protected analog outputs, 4 – 20mA and 0 – 10 VDC. These outputs can easily be inverted and can be scaled over almost any range by means of adjusting the zero control (P1) & span control (P2).
For setup purposes a LED strength indicator is provided. This LED is Green when not detecting and fades to Red as a target moves into place, depending on how much reflected signal is coming back from the target. The frequency of operation for the RPS-401A is 175kHz for the 4 – 40″ and 150kHz for the 8 – 80″. The RPS-401A barrel is constructed of PVC plastic. The barrel measures 30mm x 104mm. A standard 6′ cable is provided, or a quick disconnect (QD) version is also available.
