Rotatable Microwave Motion Radar Sensor DC12-24V Adjustable Detection Sensitivity Potentiometer Power Indicator Light Auto Door

Microwave Motion Sensor for Automatic Sliding DoorProduct BriefThis 24.125GHz microwave motion sensor is specially designed for automatic sliding doors, swing doors, revolving doors and commercial access control systems. Adopted advanced microwave radar induction technology, it can sensitively detect moving objects with a minimum speed of 5cm/s. The detection angle and sensing distance are fully adjustable to avoid false triggering caused by pedestrians beside the door. Equipped with NO/COM relay signal output, it supports 12-24V AC/DC wide voltage power supply, plug-and-play design, easy installation and wiring, widely used in supermarkets, office buildings, hotels, shopping malls and other public automatic door equipment.Product Features2.1 Rotatable Microwave Radar ProbeThe built-in microwave probe supports multi-angle rotation adjustment. You can flexibly change the detection coverage area according to on-site installation conditions, precisely target pedestrian walking zones, and reduce invalid induction and accidental door opening.2.2 Stepless Adjustable SensitivityComes with a 7-gear range potentiometer for sensitivity tuning. Rotate clockwise to extend detection distance and boost sensitivity; rotate counter-clockwise to reduce sensing range. You can customize the detection zone based on door size, foot traffic and surrounding environment.2.3 Industrial Fire-Retardant ABS HousingThe outer shell is crafted from high-strength engineering ABS plastic, featuring flame retardant, wear-resistant and anti-aging properties, ensuring stable long-term commercial use. Matte black finish matches all styles of automatic door decoration.2.4 Plug-and-Play Integrated Wiring InterfaceIntegrated unified wiring socket separates power and signal lines, no complicated welding required. A built-in power indicator clearly shows power status at a glance, facilitating post-installation inspection and debugging.2.5 Wide Voltage & Stable Relay Signal OutputWide input voltage 12V-24V AC/DC, compatible with most mainstream automatic door control boards on the market. Passive NO+COM relay output with max contact voltage 42V, max contact current 1A, and 1.5s signal hold time, delivering anti-interference stable signal transmission.2.6 Ultra-Low Speed DetectionOperating frequency at 24.125GHz, the sensor can detect slow-moving objects as low as 5cm/s. Slow walkers, shopping carts and wheelchairs can be sensed accurately without missed detection.3. Wiring InstructionGreen & Brown wires: Power Input (AC/DC 12V-24V)White & Yellow wires: Relay Signal Output (COM Common Terminal / NO Normally Open Terminal)Connect the power cable to the power supply port of the automatic door controller, connect the signal cable to the door trigger signal interface of the mainboard. Power on and adjust sensitivity to finish installation.SpecificationWorking Frequency 24.125GHzSupply Voltage AC/DC 12V-24VMax Installation Height 3.5mMinimum Detection Speed 5cm/sSignal Output Type Passive Relay NO/COMMax Contact Voltage 42V AC/DCMax Contact Current 1ASignal Hold Time 1.5 SecondsHousing Material Flame Retardant ABS PlasticMatching Cable Length 2.2 MetersProduct Dimension 118 × 79 × 50 mmPacking List1 × Microwave Motion Sensor Main Unit1 × 2.2M Wiring Harness2 × Mounting Fixing Screws1 × Box6. Wide Application ScenariosPerfect fit for all types of automatic glass sliding doors, office automatic doors, hotel entry doors, supermarket entrance gates, mall sensor doors, hospital corridor doors, bank access control doors, revolving doors and other automatic door access control equipment.7. Professional Installation TipsMount the sensor at the top center of the automatic door, installation height cannot exceed 3.5 meters;Adjust the radar probe angle to only cover pedestrian passage area;Tune the sensitivity potentiometer according to actual door width to avoid detecting vehicles or pedestrians outside the door;Keep away from metal barriers to prevent signal shielding and missed detection.
