1. Features
Introducing our cutting-edge direction-detecting microwave sensor, engineered with advanced 24G integrated chips. This innovative sensor intelligently detects approaching signals while ignoring receding signals, effectively minimizing unnecessary door activations. Plus, it offers a versatile bi-directional detection mode for added functionality. Compared to conventional microwave sensors with module antennas, our radar sensor excels with remarkable advantages:
Object moving direction recognition: Our sensor can precisely determine whether a person or object is approaching or moving away, ensuring optimal efficiency.
Superior shock resistance: The sophisticated algorithm suppresses reciprocating vibrations within a specific range, ensuring stable performance.
Ultra-long detection distance: Experience exceptional range with a maximum detection capacity for vehicles beyond 8 meters and not less than 5 meters for adults.
Impeccable product consistency: MMIC monolithic microwave integrated antenna guarantees each product maintains extraordinarily close receiving sensitivity.
2. Internal Structure
Robust four-core plug-in connector
Easily adjustable sensitivity knob
Advanced MIC integrated planar antenna
Selectable detection direction pin header

5. Installation Wiring
Begin by installing the bottom plate with precision.
Attach the installation template securely to the designated position, insert the rubber plug, and create the cable opening following the template's hole positions. Remove the outer cover and secure the bottom plate using two matching self-tapping screws.
Connect one end of the signal line to the connector and the opposite end to the power supply and control terminals of the automatic door system.
1-2 (red and black): Input Power 12V-24VAC/DC
3-4 (yellow and white): Signal output COM (normally open)
Power on the sensor, finetune the panel antenna's angle to suit the scene's requirements, and optimize sensitivity for best performance (see reference 5).
Secure the outer cover and meticulously verify the debugging outcomes.
6. Detection Orientation and Sensitivity Adjustment
Adjust detection azimuth: The panel antenna can be oriented forward, backward, left, and right for accurate positioning.
Alter the plane antenna angle to achieve varied detection distances and coverage areas as illustrated below.
Fine-tune the sensitivity for optimal detection.
MAX: Reduced microwave reflection signal, resulting in a shorter detection time.
MIN: Enhanced microwave reflection signal, leading to a longer detection time.
