Product Description

Commercial Door Sensor | 24.125GHz Microwave | Compact Size | IP54 Waterproof

This 24.125GHz Microwave Commercial Door Sensor is a professionally tailored motion detection accessory for all commercial entry doors, perfectly combining high-performance microwave sensing, ultra-compact size and IP54 waterproof protection, making it the ideal choice for busy commercial spaces like shopping malls, office buildings, retail stores and restaurant entrances. Adopting stable 24.125GHz microwave Doppler technology, it delivers accurate and fast motion detection for commercial door automation, efficiently capturing pedestrian movement at ≥5cm/s and avoiding false triggers from trivial environmental interference, ensuring smooth and stable operation of commercial swing doors, sliding doors and glass doors all day long.

Its compact and lightweight body is a core highlight for commercial installation, with a slim, space-saving profile that fits easily into narrow door frames, ceiling gaps or wall corners without protruding excessively, preserving the neat and professional appearance of commercial door facades and adapting to various commercial decoration styles with flexible concealed mounting. The IP54 waterproof and dustproof rating further enhances its practicality for commercial use, effectively resisting daily water splashes, oil mist, dust and humidity in public business areas, unlike ordinary sensors that are prone to damage in harsh commercial environments. It runs stably in a wide temperature range, supports 12-24V AC/DC wide voltage for universal commercial power adaptation, and features low power consumption for long-term uninterrupted operation. Compliant with international EMC and R&TTE standards, this compact, waterproof commercial door sensor balances small size, durable protection and reliable sensing, solving installation and environmental adaptation pain points for commercial door projects efficiently.

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)
