R-GAGE™ QT50RAF Sensor
Overview
The R-GAGE sensor emits a well-defined beam of high-frequency radio waves
from an internal antenna. Some of this emitted energy reflects back to the receiving antenna. Signal processing electronics in the sensor determine the distance from the sensor to the object based on the time delay of the return signal. The sensor can be configured (via DIP switches) to sense objects up to a
specific distance, ignoring objects beyond this distance (also called background suppression).

D Dead Zone*
* 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
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.

R-GAGE™ QT50RAF Sensor
Windows
The R-GAGE sensor can be placed behind a glass or a plastic window, but the configuration must be tested and the distance from the
sensor to the window must be determined and controlled prior to installation. There is typically a 20% signal reduction when the sensor is
placed behind a window.
Polycarbonate at 4mm thickness performs well in most situations, but the performance depends on filler materials. Thinner (1 to 3 mm)
windows have high reflection. The amount of reflection depends on the material, thickness, and distance from the sensor to the window.
Locate the sensor in a position of minimum reflection from the window, which will repeat every 6.1 mm of distance between the sensor
and the window. The positions of maximum reflection from the window repeat between the minimums, and decrease in effect until the
window is approximately 150 mm (5.9 in) away. Consult the factory for pre-tested window materials which can be used at any distance
without issue.
Additionally, the face of the window should be protected from flowing water and ice by use of a flow diverter or hood directly above the
window. Falling rain or snow in the air in front of the window, light water mist, or small beads on the face of the window are typically not
an issue. However, a thick, continuous surface of water or ice directly on the face of the window can be detected as a dielectric boundary.
