24.125GHz Glass Door Sensor with Low Power ≤2W and Anti-Interference for Automatic Door Systems
The RD24-4S Commercial Sliding Glass Door Sensor is a tailor-made motion detection solution for commercial sliding glass door systems, featuring IP54 dustproof protection and a 1.5S signal hold function for smooth, responsive access control in high-traffic commercial spaces like malls, office buildings and retail storefronts. Built with professional microwave Doppler technology, this sensor is optimized for the unique motion sensing needs of sliding glass doors, delivering accurate detection of human movement while avoiding false triggers from door sliding vibrations or ambient environmental interference—ideal for busy commercial entryways where reliable performance is essential. Its IP54 dustproof rating shields internal components from dust accumulation and minor splashes, ensuring consistent operation in high-footfall areas with frequent door use, and the rugged ABS housing stands up to daily commercial wear and tear for long-lasting durability.
The 1.5S signal hold function is a key commercial-grade design, maintaining the detection signal for 1.5 seconds to ensure the sliding glass door stays open long enough for safe, unhurried passage, even for multiple people or those carrying goods—eliminating abrupt door closures and enhancing user experience. Compact in size (120mm×80mm×50mm) and lightweight, the RD24-4S mounts discreetly on sliding glass door frames or surrounding walls without disrupting the modern aesthetic of commercial glass entryways, and the 2.2m pre-wired cable simplifies quick wiring with standard door control systems. Compatible with 12-24V AC/DC wide voltage, it integrates seamlessly into existing commercial building power setups, with a clear LED status indicator for easy installation and troubleshooting. This sensor combines commercial sliding glass door-specific calibration, IP54 dustproof reliability and practical signal hold functionality, making it the perfect plug-and-play motion detection choice for commercial sliding glass door access control.

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)
