Overview
The R-GAGE sensor emits a well-defined beam of high-frequency radio waves from an internal antenna. Some of this emitted energy is reflected back to the receiving antenna. Signal processing electronics determine the distance from the sensor to the object based on the time delay of the return signal. The sensor can be configured to two independent sensing zones.

Radar-Based Dual-Zone Narrow-Beam Sensors for Detection of Moving and Stationary Targets

• FMCW (true-presence) radar detects moving and stationary objects
• Narrow 11° × 13° beam pattern
• Two independent, adjustable sensing zones detect objects up to 40 meters away (131.2 ft)
• Easy setup and configuration of range, sensitivity, and output with simple DIP switches
• Sensing functions are unaffected by wind, falling rain or snow, fog, humidity, air temperatures, or light
• Sensor operates in Industrial, Scientific, and Medical (ISM) telecommunication band
• Rugged IP67 housing withstands harsh environments
