The Superprox Model SM902A-8 Series of long-range, ultrasonic, dual-level sensors offer a short 203 mm deadband that eliminates the need to mount the sensor at great distances from the object being detected. The sensing range stretches from 203 mm to 7.6 m. And, the 116.28 mm long housing allows the unit to be easily installed, without positioning limitations, in covers and other hard-to-mount areas.

Broad functionality enables the 12 to 24 Vdc sensors to be configured for various NPN and PNP, Normally Open, Normally Closed, or Complementary output modes for specific pump-in or pump-out, with and without alarm or setpoint, and dual alarm/dual setpoint operations.

A loss-of-echo feature can be selected to hold the output on a loss-of-echo condition. During setup and operation, a multicolor LED indicates the limits setup and operation modes; a red LED illuminates when the output is in an active state.
