Flush Mounted HMW28 Microwave Sensor from Hytronik

The Motion Sensor HMW28 (succeeding the HC002S and HMW20), with microwave technology, is a motion switch that turns on the light on detection of moving objects. The lights will be turned off after a pre-selected hold-time period if motion is not detected. This is a replacement sensor for the discontinued HC008S, HC002S and HMW20.

The flush mounted sensor also features a built-in daylight sensor for switching off light sources when sufficient natural light is detected.

This is a compact version for ceilling-mounted installation. One sensor can switch up to 800W resistive load and up to 800W inductive/capacitive load.

All the settings are fully adjustable by the user to provide high flexibility.

The sensor is discreetly fitted in any ceiling (plasterboard, suspended, false ceiling or wooden ceiling), the photocell is integrated on the top side of the sensor. 

Cut-out diameter: 78mm

Height : 73mm

Notice: The threshold of the daylight sensor is adjustable. This function can be disabled if you want to operate the sensor even with ambient day-light.
