RD79-6M Surface Mount Barrier Sensor | Replaces Ground Loop | Easy Install

Product Overview: 

The RD79-6M is a high-performance 79GHz mmWave vehicle detection sensor designed to serve as a superior ground loop replacement for automated barrier systems. This surface-mount radar eliminates the need for disruptive road cutting, offering an easy install process that significantly reduces labor costs and maintenance. Equipped with Bluetooth 5.0, the sensor allows for intuitive configuration through the “GL Control” App, enabling users to set detection distances between 0.2m and 6m with a precision of 0.1m. Its IP66-rated enclosure and advanced digital processing ensure the device remains unaffected by environmental factors such as precipitation, dust, or direct solar radiation.

This versatile barrier sensor features a Dual Mode system, allowing it to function as either a trigger mechanism for passage control or a safety anti-pinch device. In its vehicle-detect-only setting, the radar completely ignores pedestrians and utilizes direction recognition to prevent vehicles from reversing through exit lanes. With a rapid response time of ≤ 100ms and a wide operating temperature range of -40°C to +80°C, the RD79-6M provides reliable, real-time protection for both cars and people. The inclusion of RS485 and relay interfaces ensures seamless integration into existing vehicle control frameworks, making it an ideal solution for smart parking and security infrastructures.

Feature

• High-precision millimeter wave technology: Adopting the 79GHz frequency, it has extremely strong environmental adaptability and is not affected by rain, snow, dust, or strong light.
• Pedestrian filtering function (Vehicle Detect Only): It can accurately identify and ignore pedestrians within the detection range, effectively replacing traditional ground sense coils and eliminating the trouble of road-breaking installation.
• Direction recognition function: Supports direction detection, which can effectively prevent vehicles from "reversing" into the exit and improve safety.
• APP intelligent parameter adjustment: It supports parameter setting and calibration through the mobile phone "GL Control" APP, with intuitive and simple operation.
• IP66 protection level: Industrial-grade waterproof and dustproof design ensures long-term stable operation in harsh outdoor environments.
• Response and Power Consumption: Response time ≤ 100ms, average power consumption is only 1.2W (12V), energy-saving and efficient
• Detection Performance: Detection length is 1-6m, 0.5-1.5m on each side, supporting dual target detection of people and vehicles

Key Advantages of 79GHz Barrier Radar

1. High Precision and Fine-Grained Detection

Operating at a higher frequency ($79text{ GHz}$) provides a wider bandwidth, which results in superior range and velocity resolution.

• Target Recognition: It can distinguish between small objects, such as pedestrians, bicycles, and motorcycles, which are often missed by traditional loops.

• Accurate Triggering: It creates a precise "virtual curtain" that eliminates dead zones, ensuring the barrier never drops when a person or vehicle is directly underneath.

2. Directional Discrimination (Advanced Logic)

As we discussed, the ability to sense the direction of motion is a game-changer for traffic management.

• False Trigger Suppression: It ignores traffic moving away from the gate or walking parallel to it, preventing the barrier from staying open unnecessarily.

• Flow Control: Enables strict one-way access control by only responding to "approaching" targets, enhancing security in restricted areas.

3. Non-Intrusive Installation (Cost-Efficient)

Unlike inductive ground loops, radar is a surface-mounted technology.

• No Road Cutting: There is no need to excavate the pavement to bury wires, which preserves the integrity of the road and significantly reduces labor costs.

• Rapid Deployment: Installation and maintenance can be done in minutes without closing the lane for extended periods.

4. All-Weather Reliability and Durability

The 79GHz millimeter-wave technology is highly resistant to environmental interference.

• Environmental Immunity: It operates reliably in total darkness, direct sunlight, heavy rain, snow, and fog, where optical sensors (like infrared or cameras) often fail.

• Longevity: Since the device is housed in a protected casing on the barrier itself, it is not subject to the mechanical wear and tear caused by heavy vehicles driving over it (a common cause of ground loop failure).

5. Intelligent "Human-Vehicle" Differentiation

Modern 79GHz radars use sophisticated algorithms to categorize objects.

• Safety First: The radar can identify a pedestrian's unique "micro-doppler" signature. If a child or a pet follows a car into the detection zone, the radar will maintain the "stop" signal to prevent injury.

• Adjustable Zones: Users can digitally configure the detection length and width via software or mobile apps to fit narrow or wide lanes perfectly.
