Microwave Radar Sensor for Lighting, 0-16m, 10A/16A

The SUCH microwave radar sensor for lighting is a 5.8GHz motion detection switch designed for automatic lighting and load control. Using Doppler microwave technology, it provides a 0–16m adjustable sensing range with a 170° detection angle per sensor, reaching up to 360° coverage when ceiling-mounted. Available with 10A or 16A relay options, it supports incandescent, CFL, LED, LED strip, and other connected loads. Adjustable sensing distance, delay time, and photocell settings make it suitable for corridors, stairwells, parking garages, warehouses, and restrooms.

Feature

• Doppler microwave detection (5.8GHz) — can detect through non-metallic ceiling materials such as drywall, acrylic, and glass, supporting concealed installation
• Adjustable sensing range (0–16m, 4-step: 100/75/50/25%) — matches coverage to different room sizes
• 170° detection angle per sensor, up to 360° coverage when ceiling-mounted — reduces blind spots across open areas and corridors
• 16A / 10A relay ratings, up to 1500W / 1000W load capacity — supports incandescent, CFL, LED, LED strip, and exhaust fan loads
• 8-step adjustable delay time (2 sec to 20/30 min) with auto re-trigger — keeps the load on while activity continues in the sensing area, and turns off automatically once it stops
• Integrated photocell with day/night override — limits daytime triggering or enables 24-hour operation as needed
• 110–220V AC, 50/60Hz input — compatible with regional voltage standards without additional components
• Recessed ceiling mounting, Φ70–75mm cutout — fits standard ceiling openings for a flush, low-profile finish

Installation

1. Cutout: Cut a Φ70–75 mm ceiling hole.
2. Wiring: Connect wires according to the wiring diagram.
3. Insert: Place the sensor into the ceiling opening with spring clips aligned.
4. Fixing: Release the spring clips to secure the sensor.

Notes:

• Follow the wiring diagram exactly; identify the live, neutral, and control wires before connecting.
• Keep the sensing area clear of continuously moving objects, such as fans or air conditioner airflow.
• Do not install outdoors — the switch is not waterproof, and outdoor conditions can cause false triggering.
• Keep away from strong electromagnetic sources, such as radio transmitters, two-way radios, antennas, or routers.
• Install in an open area whenever possible; obstructions can reduce sensing distance and coverage.
• Sensing through thin walls, glass, acrylic, or drywall will reduce the effective sensing distance.
