Product Description

Glass Door Sensor RD24-4S | Low Power ≤2W | Adjustable Tilt Angle

This RD24-4S Glass Door Sensor is a dedicated motion detection solution tailored for all framed, frameless and sliding glass door systems, with core highlights of ultra-low power consumption ≤2W and flexible adjustable tilt angle, making it the ideal matching component for commercial storefronts, office lobbies, retail spaces and modern residential glass entryways. Adopting stable 24.125GHz microwave Doppler technology, it delivers precise and responsive motion sensing exclusively calibrated for glass door usage, efficiently capturing pedestrian movement at ≥5cm/s and avoiding common false triggers from light refraction and glass surface reflections, ensuring smooth and consistent automation of glass doors without frequent misoperation or lag.

Its star feature is the controllable low power draw of ≤2W, enabling 24/7 uninterrupted operation with minimal energy loss, drastically cutting long-term power costs for glass door systems and meeting energy-efficient usage demands for both commercial and residential scenarios. The adjustable tilt angle design further elevates its practicality, allowing free fine-tuning to adapt to different glass door installation heights, passage widths and mounting positions, customizing the detection coverage to fit the exact pedestrian entry area perfectly without over-sensing irrelevant spaces. Slim and low-profile in structure, it mounts discreetly on glass door frames or adjacent walls, preserving the sleek, transparent aesthetic of glass door designs without disrupting overall decor. It supports 12-24V AC/DC wide voltage compatibility for universal power adaptation, features hassle-free quick installation with no complex debugging, and complies with international R&TTE and EMC standards for safe, reliable long-term use, standing out as a practical, energy-saving motion sensor dedicated to glass door automation.

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
Detection distance is too close	Low sensitivity; microwave module angle <45°; sensor blocked	Adjust sensitivity potentiometer to 1/2 or higher; set module angle to ≥45°; remove occluding objects

Application Scenarios

The RD24-4S is a multi-scenario motion detection sensor with high adaptability, primarily applicable to:

Automatic Door Systems: Sliding doors, swing doors, glass induction doors (commercial buildings, shopping malls, office buildings)
Security & Monitoring: Perimeter security detection, indoor human motion induction (residential, factory, warehouse)
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)
