Product Description
RD79-6M Smart Barrier Gate Radar Sensor for Vehicle Pedestrian Detection Anti-Crush Protection and Parking Access Control
Product Overview

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 Barrier Gate Radar Sensor product overview

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 radar sensor installation and application diagram

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.

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
