The sensor adjusts continuously across a dimming range of 10-100%, maintaining consistent overall light levels while reducing energy consumption during daylight hours.\u003c\/p\u003e\n\u003cp\u003eDesigned for commercial, office and residential installations where daylighting varies throughout the day, the sensor mounts in three ways: recessed into ceilings or walls via an 18mm cut-out, surface-mounted using the included sleeve, or panel-mounted into control enclosures. The 750mm pre-wired cable provides enough length for typical ceiling cavity routing to a driver or controller. The adjustable lux threshold spans 10-500 lux, allowing the sensor to be calibrated to different room types and window exposure.\u003c\/p\u003e\n\u003cp\u003eThe white polycarbonate housing measures 22mm diameter by 24mm height when surface-mounted, with a 26mm recessed depth when fitted flush. The IP20 rating limits use to dry indoor environments. The sensor pairs with any 1-10V dimmable LED driver and can be wired in parallel with compatible motion sensors to create a combined daylight-harvesting and occupancy-sensing control system. The Class III rating means the sensor operates at extra-low voltage and does not require earthing.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e22 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e24 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecessed Depth\u003c\/td\u003e\n\u003ctd\u003e26 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCut-out Diameter\u003c\/td\u003e\n\u003ctd\u003e18 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCut-out with Sleeve\u003c\/td\u003e\n\u003ctd\u003e28 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003ePolycarbonate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eWhite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClass\u003c\/td\u003e\n\u003ctd\u003eIII\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Voltage\u003c\/td\u003e\n\u003ctd\u003e1-10V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable Length\u003c\/td\u003e\n\u003ctd\u003e0.75 m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_4191649_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/manual_1492476.pdf\" target=\"_self\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat LED drivers is this sensor compatible with?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe sensor works with any LED driver that accepts a 0-10V or 1-10V dimming control signal. Common compatible drivers include those labelled 'DALI\/1-10V dimmable' or '0-10V analogue dimming'. Check the driver specification sheet to confirm 1-10V input compatibility before wiring.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan this sensor be used with motion sensors?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The OS022 can be wired in parallel with compatible Knightsbridge motion sensors to create a combined control system where lighting dims based on daylight availability and switches off when the space is unoccupied.

This allows calibration to suit different room types: lower thresholds for offices with large windows, higher thresholds for spaces with minimal natural light.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between recessed and surface mounting?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eRecessed mounting requires an 18mm cut-out in the ceiling or wall, with the sensor sitting flush and projecting 26mm into the cavity. Surface mounting uses the included sleeve over a 28mm cut-out, leaving the 24mm-high sensor body visible on the surface. Panel mounting is for control enclosures and uses the same 18mm aperture as recessed installation.\u003c\/p\u003e","brand":"Knightsbridge","offers":[{"title":"Default Title","offer_id":45293594935563,"sku":"OS022","price":11.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/1679328_b9248a90-8a40-49e4-a1c7-31de06243119.jpg?v=1714660943","url":"https:\/\/niori.co.uk\/products\/1-10v-daylight-sensor-white-22mm-recessed","provider":"Niori","version":"1.0","type":"link"}
