This 24.125GHz Sliding Glass Door Sensor is a precision-engineered motion detection solution tailored for sliding glass door systems, boasting a high-performance planar antenna and advanced blinder-free detection for seamless, reliable operation in commercial and residential entryways. Tuned to the 24.125GHz microwave band, the sensor’s integrated planar antenna is designed for wide, focused coverage, creating a tailored detection field that aligns perfectly with the movement path of sliding glass doors—eliminating blind spots and ensuring accurate capture of human motion from all typical entry angles, even for large double sliding glass door setups. What sets this sensor apart is its blinder-free detection technology, which filters out false triggers from glass reflections, ambient light, and minor environmental disturbances, preventing the sensor from being "blinded" by common sliding glass door surroundings and ensuring only intentional motion initiates a response.
Optimized for sliding glass door use, the sensor delivers consistent performance with a minimum detectable speed of 5cm/s, matching the natural movement of people approaching entryways, and its compact ABS housing mounts discreetly on door frames or adjacent walls without compromising the sleek aesthetic of glass door installations. Built to withstand daily use, it features an IP54 dustproof and waterproof rating, operating stably in temperatures from -20℃ to +55℃ for year-round reliability in both indoor and covered outdoor sliding glass door setups. Compatible with 12-24V AC/DC wide voltage and low power consumption of ≤2W, it integrates effortlessly into existing door control systems, with a clear LED status indicator for easy installation and quick troubleshooting. Ideal for malls, offices, and modern homes, this sensor merges 24.125GHz precision, planar antenna coverage, and blinder-free detection for a hassle-free sliding glass door motion sensing experience.

Installation & Adjustment Guide
The sensor's performance is closely related to correct installation and adjustment. Simple operation with no professional tools required:
Mounting Requirements
Avoid vibration positions, neon lamp proximity and sensor occlusion; do not touch internal electronic parts during installation.
Sensitivity Adjustment
Rotate the sensitivity potentiometer gently and slowly; the sensitivity value determines the size of the detection field (adjust to 1/2 or higher for short detection distance).
Angle Adjustment
Planar antenna lateral angle = detection field position; vertical angle = detection field depth; set microwave module angle to ≥45° for optimal detection.
Status Check
LED flashes after power-on (normal standby); LED lights up continuously when a moving target is detected (detection trigger).
Troubleshooting Guide
Fault Phenomenon
Probable Causes
Corrective Action
Door does not open & LED no light
Sensor power off
Check wiring connection and power supply validity
Door opens/closes constantly
Sensor detects door vibration/movement; interference source in detection range
Fix the sensor firmly; increase tilt angle/reduce sensitivity; remove interference sources in the detection field
Industrial Automation: Conveyor belt motion detection, equipment start/stop induction (light industry production lines)
Intelligent Building: Smart lighting induction, air conditioning induction (public areas such as corridors and elevators)
