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 back of the

sensor. The sensor is plug-in ready for immediate operation.

The sensitivity was 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 back of the sensor.

Sensor Configuration

The sensing zone distance, sensitivity, and output configuration can be selected via the DIP switches on the back of the

sensor. Use the included spanner to open the screw-off cover on the back 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.
