Datasheet

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

WARNING: Not To Be Used for Personnel Protection
Never use this device as a sensing device for personnel protection. Doing so could lead to

serious injury or death. This device does not include the self-checking redundant circuitry necessary

to allow its use in personnel safety applications. A sensor failure or malfunction can cause either an
energized or de-energized sensor output condition.

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.

The two sensing zones are factory pre-set to default distances; they can be reconfigured for different distances using the
DIP switches on the side of the sensor. The sensor is plug-in ready for immediate operation.

The sensitivity is precalibrated at the factory, assuming that the sensing field will be clear of obstacles. The sensitivity can
be adjusted using the DIP switches on the side of the sensor.

Sensor Configuration

Use the included spanner to open the screw-off cover on the side of the sensor and access the DIP switches.

Important: Tighten the DIP switch cover a full quarter turn after contact to maintain the watertight
seal.

Typical dead zone: 0.4 m (1.3 ft) for moving and 1.0 m (3.3 ft) for stationary targets, but varies with target reflectivity.
