Wall Panel Microwave Radar Sensor Switch, 220V AC, 10A/16A

The SUCH microwave radar sensor switch is a 220V AC wall-mounted motion sensor for standard 86-type wall boxes. It uses 5.8GHz Doppler radar to detect motion through non-metallic materials such as plasterboard, glass, and thin partitions. Detection is not affected by ambient temperature or lighting conditions. The sensor automatically controls connected lights or ventilation fans based on motion and ambient light. Detection range, delay time, and light threshold are adjustable using onboard DIP switches, making it suitable for corridors, stairwells, garages, storerooms, and bathrooms.

Feature

• 5.8GHz Doppler microwave sensing — Detects motion through non-metallic materials such as plasterboard, glass, and thin walls. Detection is not affected by ambient lighting or temperature.
• Detection range: 0–8m front / 0–4m side — Four DIP-switch settings provide 25%, 50%, 75%, or 100% of the maximum range.
• 170° detection angle — Provides wide-angle coverage for wall-mounted installation.
• Delay time: 2 seconds to 20 minutes — Eight preset settings (2s, 16s, 30s, 60s, 90s, 5min, 10min, 20min) determine how long the load remains on after the last detected motion.
• Built-in ambient light sensor — The light-sensing function can be enabled or disabled via DIP switch for daytime or nighttime operation.
• 4-wire connection with 3-wire installation support — Terminals are provided for Line (L), Load Output (Lo), Neutral (N), and Fire Alarm. The Fire Alarm terminal can be left unconnected for standard 3-wire installation.
• 10A and 16A load options — The 10A version supports up to 1000W incandescent, 400W CFL/exhaust fan, 200W LED, or 5m LED strip. The 16A version supports up to 1600W incandescent, 800W CFL/exhaust fan, 300W LED, or 8m LED strip.
• Flame-retardant housing with status indicator — The housing provides flame-retardant protection, while the green LED indicates operating status during installation and maintenance.
