Banner Engineering R-Gage QT50R retroreflective radar sensor

Micromax Sensors has added a retroreflective model to Banner Engineering’s range of R-Gage QT50R radar sensors.

Now with both adjustable-field and retroreflective models available, they can solve more diverse and complex vehicle detection applications - effectively detecting trains, cars, trucks and cargo alike.

Designed with train detection in mind, they use frequency modulated continuous wave radar to provide detection of moving or stationary objects in areas where photoelectric, ultrasonic and magnetic sensors fall short.

The sensor emits a well-defined beam of HF from an internal antenna, which processes the signal reflected back to the receiving antenna. The sensor is designed to detect objects within a user-defined distance, ignoring objects and any background beyond the setpoint.

Common applications of the adjustable-field radar sensor include: detection of vehicles on roads and near intersections; boat detection for locks and dams; proximity detection for large shipyard cranes and cargo; car counting for parking ramps, gates and drive throughs; subway and light-rail logistics.

The maximum sensing range depends on the size and shape of the target but the standard adjustable-field radar sensor peaks at 15 m. Customisable sensors are available with ranges up to 40 m and myriad advanced capabilities, including two independent sensing zones, narrower beam patterns, analog output, velocity/direction, heartbeat for health monitoring and higher-gain antennas for more sensitive detection.
