Millimeter Wave Radar Anti-smashing Barrier Vehicle Detector Barrier Sensor for car Boom Barrier Gate

Millimeter Wave Radar Anti-smashing Barrier Vehicle Detector Barrier Sensor for car Boom Barrier Gate

Model No.: R02

This parking lot millimeter-wave radar only has NO (Normally Open) ports

 (no NC ports) for these key reasons:

1: Fits barrier anti-crushing logic: NO stays disconnected normally, conducts only when detecting vehicles/pedestrians to signal the barrier to stay up—perfectly matches barrier operation needs.

2: Safer & fewer malfunctions: NO avoids false triggers from wiring issues (unlike NC which may block barriers permanently if faulty) and aligns with power-off safety protocols.

3: Simplifies installation/maintenance: Reduces ports/circuits, cuts costs, and eliminates wrong wiring risks (works directly with most barrier control modules).

4: Universal compatibility: Matches mainstream barrier control systems  (most barriers are designed for NO anti-crushing signals, no extra signal conversion needed).

Radar installation and operation tutorial

(1.1) The anti-smashing radar is installed on the barrier gate box perpendicular to the direction of the lane (or installed on the column next to the box). The installation height is recommended to be 0.6M from the bottom edge of the radar to the ground, and 15-25CM from the gate lever on the left and right (refer to the schematic diagram).

(1.2) The barrier gate chassis must be fixed firmly to prevent the chassis from shaking when the gate machine is working.

(1.3) Within the detection range of the radar, except for the brake lever, there must be no obstacles, such as road cones, metal manhole covers, isolation fences, signs and the like.

(1.4) The schematic diagram of the barrier radar installation specification is as follows:

As shown in the figure below, first determine the installation location, and then punch a threading hole and 2 fixing holes on the box body. (Positioning hole self-adhesive stickers and fixing screws are provided in the product package), then fix the radar on the box and tighten the fixing nuts.

Radar Setting Pole Length Tutorial

Step 1: Press and hold the button without releasing it

Set detection distance

Press until the green light is on and the red light is off, each time the red light flashes, the detection distance will increase by 0.5 meters, and the effective setting distance will cycle within 1-6 meters (the starting distance is 1 meter). After setting the distance, release the button to enter the next step.

Step 2: Press and release the button

learning scene environment

Automatically learn the background of the scene (the red light and the green light flash at the same time); wait for 20 seconds, the radar saves the parameters and exits, the setting is completed; the radar works normally (the red light is always on)

For example, if you set up a 4m straight pole: (the detection distance should be 0.5m shorter than the length of the pole)

Press and hold the button for the first time without releasing it until the red light flashes five times (0.5 meters each time) and then release it (set distance

2.5 meters + 1 meter starting distance), at this time the detection distance is 3.5 meters;

After pressing the button for the second time, release it immediately, the traffic light flashes at the same time, and then wait for 20 seconds

Just learn the scene environment (at this time, there are no people, cars and other objects within the detection range of the barrier gate).
