Description
RD79-6M 79GHz Millimeter Wave Barrier Gate Radar Sensor for Parking Anti-Crush Protection and Vehicle Trigger Detection

The RD79-6M 79GHz Barrier Gate Radar Sensor provides advanced anti-crush protection and trigger detection for parking barrier gates, entrance and exit management systems, parking lots, underground garages, and vehicle access control systems.

RD79-6M 79GHz Millimeter Wave Barrier Gate Radar Sensor for Parking Anti-Crush Protection and Vehicle Trigger Detection

This 79GHz millimeter wave radar sensor detects vehicles or pedestrians within the barrier arm zone, enabling safer lifting and lowering actions. Compared to traditional loop detectors or infrared sensors, the RD79-6M utilizes 79GHz LFM-CW radar technology with a 2T4R antenna structure, delivering high distance resolution, accurate target detection, and stable operation in outdoor or complex parking environments.

RD79-6M 79GHz Millimeter Wave Barrier Gate Radar Sensor for Parking Anti-Crush Protection and Vehicle Trigger Detection

The radar supports multiple barrier arm types including straight arm, folding arm, fence barriers, and advertising barriers. It features multiple detection modes: anti-crush mode, trigger mode, and inclined-mount trigger mode. With Bluetooth app configuration and RS485 communication, installers can conveniently adjust parameters during project commissioning.

Key Features
  • Dual Functionality - Integrates anti-crush protection and trigger detection in one radar sensor
  • 79GHz High Precision Radar - 79-81GHz millimeter wave detection with 4cm distance resolution
  • Human-Vehicle Separation - Supports vehicle-only or pedestrian plus vehicle detection modes
  • Multiple Barrier Arm Compatibility - Works with straight arm, folding arm, fence arm, and advertising barrier gates
  • Bluetooth App Debugging - Configurable via GL Control app with Bluetooth connectivity
  • Adjustable Detection Range - Customizable left/right distance, long detection distance, and near no-detection distance
  • RS485 Communication & Relay Output - Compatible with barrier gate controllers and parking access control systems
  • IP66 Outdoor Protection - PC and aluminum alloy housing with -40℃ to +80℃ operating range

RD79-6M 79GHz Millimeter Wave Barrier Gate Radar Sensor for Parking Anti-Crush Protection and Vehicle Trigger Detection
Applications
  • Parking barrier gates
  • Parking lot entrances and exits
  • Underground garage access control
  • Residential community parking gates
  • Commercial building parking systems
  • Vehicle entrance management
  • Straight arm barrier gates
  • Folding arm barrier gates
  • Fence barrier gates
  • Advertising barrier gates
  • Barrier gate anti-crush protection
  • Vehicle trigger detection
Installation Notes

The radar is installed on the barrier gate cabinet side. Installation requires a Φ17mm opening hole, with horizontal distance from the barrier cabinet approximately 23-33cm, and fixed hole distance from the ground varying according to barrier size.

Recommended installation points:
  • Install the radar on the barrier gate cabinet side facing the barrier arm area
  • Keep the radar detection area aligned with the barrier arm protection zone
  • Set the correct barrier arm type and direction in the app
  • Perform background learning after installation and parameter adjustment
  • Keep people and vehicles away from the detection zone during background learning
  • Save configuration after completing all parameter settings
