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 Plastic Valox 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. 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. An optional quick disconnect plug is available.

 Proximity Detection

Proximity detection is the detection of an object at a given distance. The detection range of the RPS-401,426 is controlled by the "Range Control" potentiometer. Any object within the desired range is detected, while objects out of range are ignored. The range of the RPS-401 is either 4" to 40" or 8" to 80". The range of the RPS-426 is 8" to 80" only. This means that in the proximity mode the object will be detected from whatever detect point is set to the minimum sensing range of the sensor either 4" or 8". The hysteresis control needs to be off by turning the potentiometer fully counterclockwise.

 

Hysteresis Detection

The RPS-401,426 is furnished with Hysteresis Control by means of a second potentiometer. This control allows you to adjust the turn-off point while the range control adjusts the turn on point. (Example: Range pot set for 10", Hysteresis pot set for 20". With these settings the sensor will detect when the target reaches 10" and stays on as the target moves away to 20".) This Hysteresis can be adjusted from .5" to 40" from the detect point with the 40" sensor and 1" to 80" with the 80" sensor
