High Light	24.125GHz microwave motion sensor ，12-24V AC/DC door sensor ，easy mounting commercial door sensor

Commercial Door Sensor 24.125GHz | 12-24V AC/DC | Easy Mounting | Sensitivity

This 24.125GHz Commercial Door Sensor is a tailor-made motion detection solution for all commercial entryway setups, featuring universal 12-24V AC/DC voltage support, hassle-free easy mounting, and customizable sensitivity—ideal for high-traffic commercial spaces including office buildings, retail storefronts, shopping malls and service centers. Powered by professional 24.125GHz microwave Doppler technology, it delivers precise motion sensing of human movement at ≥5cm/s, with a dedicated sensitivity adjustment potentiometer that lets you fine-tune the detection range for diverse commercial door types: crank up sensitivity for wide commercial entry bays to capture all approaching traffic, or lower it for narrow storefront doors to filter out interference from street passersby, eliminating false triggers and ensuring smooth door automation.

Its 12-24V AC/DC wide voltage compatibility is a game-changer for global commercial applications, seamlessly adapting to standard commercial building AC power and low-voltage DC control systems without extra power converters or adapters, cutting down on installation parts and matching regional power specifications with zero hassle. The easy mounting design is optimized for commercial fit-out efficiency: with a compact ABS housing and lightweight build, it installs directly to door frames, walls or ceilings with basic hardware—no professional tools or technical expertise required. The 2.2m pre-wired cable fits standard JST and relay COM/NO interfaces, enabling quick wiring with existing commercial door control systems for fast on-site setup.

Built to withstand the rigors of commercial use, it features an IP54 dustproof and waterproof rating, operating stably in -20℃ to +55℃ temperatures, and ultra-low power consumption of ≤2W for energy-efficient 24/7 continuous operation. A clear LED status indicator provides real-time power and detection feedback for quick troubleshooting, and it complies with R&TTE and EMC international standards for interference-free performance near commercial electronics like neon signs and cash registers. This sensor blends flexible power compatibility, fast commercial installation and tailored sensitivity, making it a reliable, cost-effective motion detection choice for every commercial door automation need.

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)
