1. Features
Introducing our cutting-edge direction-detecting microwave sensor, meticulously engineered with 24G integrated chips. This marvel of modern technology excels by precisely detecting approaching signals while strategically ignoring those moving away, ensuring seamless operation without unnecessary door openings. Versatility is at your fingertips with the option to switch to bi-directional detection mode. Compared with typical market offerings featuring module antennas, our sensor stands out with unparalleled advantages:
Object moving direction recognition: Experience precision as the sensor accurately discerns whether a person or object is approaching or retreating.
Superior shock resistance: Our advanced algorithm effortlessly neutralizes any reciprocating vibrations within a specified range, ensuring flawless performance.
Ultra-long detection distance: Boasting a remarkable range, it detects vehicles over 8 meters away and adults at distances not less than 5 meters.
Outstanding product consistency: The MMIC monolithic microwave integrated antenna guarantees extraordinary receiving sensitivity for each unit, ensuring uniform performance.
2. Internal Structure
Four-core plug-in connector ensures robust connectivity.
Sensitivity adjustment knob allows for precise calibration.
MIC integrated planar antenna for superior signal processing.
Detection direction selection pin header for customizable detection settings.
3. Working Principle
Proximity: Confident detection of approaching entities. Away from: Effortless disregard for departing entities.

5. Installation Wiring
Begin by installing the durable bottom plate.
Position the installation template at the ideal location, secure the rubber plug, and create a cable hole aligned with the template. Uncover the outer casing and affix the bottom plate using the provided self-tapping screws for a secure fit.
Connect one end of the signal line firmly into the connector, then attach the opposite end to the power supply and control terminals of the automatic door.
1-2 (red and black): Power input 12V-24VAC/DC ensures optimal power supply.
3-4 (yellow and white): Signal output COM(normally open) for reliable communication.
Power the sensor, then fine-tune the panel antenna's angle to suit the scene's requirements, adjusting sensitivity for peak performance (see reference 5).
Secure the outer cover and confirm the alignment with debugging results for seamless operation.
6. Detection Orientation And Sensitive Adjustment
Fine-tune detection azimuth by adjusting the panel antenna in all directions-forward, backward, left, and right.
Modulate the angle of the plane antenna to achieve varying detection distances and areas, as illustrated in the figure below.
Calibrate sensitivity with precision.
MAX: Experience weaker microwave reflection signals and shorter detection times for quick response.
MIN: Harness stronger microwave reflection signals for prolonged detection times and comprehensive analysis.
