Description

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

The RD24-4S 24.125GHz Microwave Radar is a versatile, user-centric motion detection solution built for universal door automation and commercial access control, standing out with reliable blinder-free detection and truly effortless installation to streamline setup and boost daily performance. Powered by advanced 24.125GHz microwave Doppler technology, this radar is engineered to eliminate detection dead zones completely, covering the full entry path of automatic doors, commercial doors and sliding glass doors with consistent, uniform signal coverage. It accurately captures pedestrian movement at ≥5cm/s without blind spots or missed triggers, even in corner-mounted or high-installation scenarios, ensuring smooth, uninterrupted door operation for high-traffic malls, offices and retail spaces.
What sets this model apart is its hassle-free installation design, crafted to skip complex tools and professional debugging: it comes with a pre-wired 2.2m cable for direct connection to standard door control systems, and its compact, lightweight ABS housing supports quick surface mounting on door frames, walls or ceilings with basic hardware. No complicated calibration is needed, making it perfect for quick commercial retrofits and new door projects alike. Built with durable internal components, it runs steadily with low power draw, resists minor environmental interference, and complies with international R&TTE and EMC standards for safe, long-term use. Free of bulky parts or tricky wiring, this blinder-free microwave radar combines reliable full-coverage sensing and ultra-easy setup, making it the ideal plug-and-play choice for diverse door automation needs without extra installation hassle.

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)
