        Major Tech MS371 | 360° True Presence Microwave Sensor | IP65

        The Major Tech MS371 is a high-performance microwave motion and presence sensor designed for accurate control of lighting or connected devices in both indoor and outdoor spaces. It uses 24GHz CW radar technology to detect both movement (up to 9m) and still presence (up to 6m), providing smarter automation compared to standard motion-only sensors.

        With adjustable lux sensitivity (from <3 to 2000 Lux), time delay settings (10 sec to 12 min), and IP65 weatherproof protection, the MS371 is ideal for carports, patios, bathrooms, or corridors. It handles up to 2000W incandescent or 1000W LED/CFL and installs easily into ceilings from 2-4m high.

        MS371 Features

        • 360° Presence & Motion Detection: Detects subtle stillness and active motion
        • Radar-Based Precision: 24GHz CW radar distinguishes movement vs presence
        • Customisable Settings: Lux: <3-2000, Delay: 10s-12min
        • Weatherproof IP65 Rating: Safe for sheltered outdoor and indoor installs
        • High Load Capacity: 2000W incandescent / 1000W LED or CFL

        MS371 FAQ

        Q: Can this sensor detect subtle presence without motion?
        A: Yes, it distinguishes between still presence and movement using radar technology.

        Q: Is the sensor suitable for outdoor installations?
        A: Yes, its IP65 rating makes it suitable for covered outdoor areas.

        Q: What cutout size is required for installation?
        A: It fits ceiling cutouts between Ø63mm and Ø66mm.
