Product Description

Microwave Radar | 4m×2m Detection | IP54 Protection | Anti-Interference

This Microwave Radar is a high-performance motion detection solution engineered for diverse door automation and commercial access control scenarios, highlighted by a generous 4m×2m detection range, robust IP54 protection, and advanced anti-interference technology—delivering consistent, reliable sensing in high-traffic and complex electromagnetic environments. Calibrated for optimal performance at the standard 2.2m mounting height, its 4m(W)×2m(D) detection field covers the full entry area of most automatic, glass, and commercial doors, with a high-gain planar antenna ensuring blind-spot-free motion capture of targets moving at ≥5cm/s. This wide coverage is perfect for busy malls, office lobbies, and retail storefronts, eliminating missed detections even during peak foot traffic and adapting seamlessly to both narrow passageways and wide entry bays via simple angle adjustment.

A core strength of this radar is its anti-interference design, which filters out electromagnetic disturbances from neon lamps, commercial electronics, and power supply equipment—common culprits of false triggers in busy commercial spaces. It also rejects mis-signals from door vibrations and ambient environmental movement, ensuring only intentional human motion initiates a response for smooth door automation. Paired with IP54 dustproof and waterproof protection, it shields internal components from daily splashes, dust accumulation, and minor physical wear, performing stably in both indoor semi-enclosed areas and covered outdoor entryways. It withstands extreme temperatures from -20℃ to +55℃, making it suitable for year-round use across different climates.

Built for practical integration, the radar features ultra-low power consumption (≤2W) and 12-24V AC/DC wide voltage compatibility, fitting effortlessly into existing door control power setups without additional adapters. A clear LED status indicator simplifies quick installation and troubleshooting, while its compact ABS housing enables discreet mounting on door frames or walls. Compliant with R&TTE and EMC international standards, this microwave radar merges expansive detection, rugged protection, and interference-free performance, making it a versatile, low-maintenance choice for all commercial motion sensing and door automation needs.

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)
