SDEHM4A is a microwave sensor operating at a high electromagnetic wave frequency of 10.525 GHz. This enables the device to detect moving objects behind thin non-metallic surfaces such as drywall, glass, and similar materials. The sensor is powered by a mains supply voltage of 100–240 V AC and provides a 0/1–10 V DC output, allowing dimming via the output signal. It features a detection range of up to 10 m and a maximum installation height of 10 m.
The product also includes a built-in photocell that monitors the ambient light level. It can operate as a 2.4 GHz RF remote-control device for dimmers controlling single-color, CCT, RGB, RGBW, and RGB+CCT LED lighting. The device is used as a control unit in automated indoor lighting systems.
