Operating on 120–277V, it uses dual-technology sensing (PIR + acoustic) to detect occupancy and control connected lighting loads. The unit features Partial Auto-On operation (auto-on to 50%) and supports 0–10V dimming for compatible lighting systems, helping improve energy efficiency while maintaining user control.\u003c\/p\u003e\n\u003ch3\u003eKey Features \u0026amp; Design\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctionality:\u003c\/strong\u003e Dual-technology occupancy sensor (PIR + acoustic) providing partial auto-ON (50%) and automatic OFF control, with integrated 0–10V dimming capability\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation context:\u003c\/strong\u003e Wallbox-mounted device designed for line-voltage commercial lighting systems, suitable for retrofit or new installations\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNotable specifications:\u003c\/strong\u003e 120–277V AC operation; dual-technology sensing (PIR + acoustic); wall-to-wall (~180°) coverage; partial auto-ON (50%); 0–10V dimming compatibility; single-gang wallbox mounting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContractor-relevant details:\u003c\/strong\u003e Interchangeable line\/load wiring simplifies installation; supports both neutral and no-neutral configurations; shallow design (\u0026lt;1” depth) fits crowded wallboxes; supports 0–10V dimmable lighting loads\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePerformance \/ Benefits\u003c\/h3\u003e\n\u003cp\u003eIn real-world applications, the SWX-121-D-BK provides reliable occupancy-based lighting control while reducing energy consumption. Dual-technology sensing improves detection accuracy in spaces with limited motion or obstructions, while partial auto-on operation supports energy code requirements. Integrated 0–10V dimming enables flexible light level adjustment for improved comfort and efficiency, making it well-suited for offices, conference rooms, corridors, and other commercial spaces.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"SensorWorx","offers":[{"title":"Default Title","offer_id":46030029619340,"sku":"SWX-121-D-BKSENSORWORX","price":125.54,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0697\/0048\/5260\/files\/sensorworx-swx-121-d-bksensorworx-9122046.jpg?v=1778554400","url":"https:\/\/www.interactivelightingsupply.com\/products\/sensorworx-swx-121-d-bk-dual-tech-wall-sensor-0-10v-120-277v-black","provider":"Interactive Lighting Supply","version":"1.0","type":"link"}
