R-GAGE™ QT50R Series Sensor

Radar-Based Vehicle Detection Sensor

Features

• Reliably detects vehicles and trains based on frequency-modulated continuous-wave
(FMCW) radar technology

• Detects objects up to 7.2 m (24') away using a fixed background reference target up
to 8 m (26') away

• Detection is unaffected by wind or changing air temperatures

• Easy to set up using sealed push button or remote wire

• Operates in Industrial, Scientific, and Medical (ISM) telecommunication band; no
special license required

• 15 to 30V dc operation

• Rugged IP67 housing for harsh environments

WARNING . . . Not To Be Used for Personnel Protection

Never use these products as sensing devices for personnel protection. Doing so could lead to serious injury or death.

These sensors do NOT include the self-checking redundant circuitry necessary to allow their use in personnel safety applications. A
sensor failure or malfunction can cause either an energized or de-energized sensor output condition. Consult your current Banner
Safety Products catalog for safety products which meet OSHA, ANSI and IEC standards for personnel protection.

Overview

The R-GAGE sensor emits high-frequency radio waves from an internal antenna, which
forms a well-defined beam. Some of this emitted energy is reflected back to the receiving
antenna. Signal processing electronics determine the distance from the sensor to the
vehicle based on the time delay of the return signal. The sensor is configured to operate
like a retroreflective photoelectric sensor. See Figure 3.

Sensor Programming

1. Mount the sensor securely. Align the sensor with the background target, making the

face of the Sensor as parallel as possible to the background target.

In programming mode (only after the TEACH push button is pressed), the red Signal

LED will flash faster as the alignment improves; solid ON is best. If the red Signal LED
does not flash, then the background target is not sufficient and a different target must
be used, such as a metal plate or a corner cube reflector.

2. Verify that the area between the sensor and the background is clear, and follow the
programming procedure in the table below.

General Notes on Programming

• Once the sensor enters TEACH mode, it will default to the previous settings and exit
TEACH mode after one minute.

• To exit TEACH mode and return to the previous settings, push and hold the TEACH
push button (or pulse the remote line) for more than two seconds.
