The sensor detects movement across a 120° horizontal arc at ranges up to 5 metres and switches connected lighting on automatically when motion is detected in low ambient light conditions.\u003c\/p\u003e\n\u003cp\u003eIntended for corridors, stairwells, lobbies, utility rooms and small commercial spaces where automatic switching reduces unnecessary lighting use, the module requires a 47mm minimum back box depth and wires via live and neutral connections to the mains supply. The sensor supports loads up to 100W LED or 200W incandescent, covering typical residential and small commercial lighting circuits. The internal timer holds lights on for a pre-set three minutes after the last detected movement before switching off automatically.\u003c\/p\u003e\n\u003cp\u003eThe grey polycarbonate construction and flush-mount design suit modern interiors and commercial fit-outs where sensors need to blend into wall-mounted modular switch plates rather than standing out as separate ceiling or wall-mounted boxes. The lux sensitivity adjusts internally to prevent the sensor triggering during daylight hours, so lights only activate when both movement is detected and ambient light falls below the threshold. The IP20 rating limits the module to dry indoor locations.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e50 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e50 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecessed Depth\u003c\/td\u003e\n\u003ctd\u003e40 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin.
