R-GAGE™ QT50RAF Sensor
Radar-Based Adjustable Field Sensors for Detection of Moving and Stationary Targets
Features
• FMCW (true-presence) radar detects moving and stationary objects
• Adjustable sensing field — ignores objects beyond setpoint
• 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; no special license required
• Rugged IP67 housing withstands harsh environments

CAUTION: Make No Modifications to this Product
Any modifications to this product not expressly approved by Banner Engineering could void the user's authority to operate the product. Contact the Factory for more information.
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 deenergized sensor output condition.

Cabled models only are listed. For integral 5-pin Euro-style (M12) quick-disconnect fitting, add suffix "Q" to the model
number (e.g., QT50RAFQ-xx). QD models require a mating cordset; see Quick Disconnect (QD) Cordsets on page 7.

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).

X Minimum setpoint distance 2 m (6.6 ft) 3 m (9.8 ft)
Y Maximum setpoint distance 15 m (49.2 ft) 15 m (49.2 ft)
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.
DIP Switch Functions
Switch Function
1, 2, 3 Sensing distance (detects objects from sensor face to this point)
4, 5, 6 Sensitivity (higher sensitivity sees weaker objects and has a larger beam pattern)
7 Normally open/normally closed output functionality
8 Response Speed
DIP switch 1 is on the left and DIP switch 8 is on the right.
