RPS-401A/RPS-426A Analog Ultrasonic Sensors Description
The RPS-401A, RPS-426A 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, 426A 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 135kHz for the 8-80". The RPS-426A has an 8-80" range and operates at a frequency of 150kHz. The RPS-401A barrel is constructed of PVC plastic, and the RPS-426A is Stainless Steel. The barrel measures 30mm x 104mm. A standard 6' cable is provided, or a quick disconnect (QD) version is also available.
