The twin-beam design requires both beams to be broken simultaneously before triggering an alarm, which eliminates false alarms from birds, falling leaves, and other single-point interruptions. A built-in laser alignment system makes installation fast and precise, and the IP55 weatherproof housing with anti-frost circuitry keeps the sensor operating reliably in rain, snow, and temperature extremes from -13 to 131 degrees F. It integrates with any \u003ca href=\"\/collections\/security-surveillance\"\u003esecurity alarm panel\u003c\/a\u003e through standard NO\/NC relay and tamper switch outputs.\u003c\/p\u003e\n\u003cp\u003eThe E-960-D190Q runs on 10-30 VAC\/VDC non-polarized input, drawing only 70mA, so it connects to the same power supplies already used in most alarm installations. The variable interrupt speed (50-700 msec) lets installers tune sensitivity to the environment: shorter interrupt times for high-security zones where fast detection matters, longer times for areas with frequent non-threat movement like swinging gates or tree branches near the beam path.\u003c\/p\u003e\n\u003ch3\u003eWhere the E-960-D190Q Fits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePerimeter security for commercial properties\u003c\/strong\u003e where the twin-beam sensor creates an invisible detection line along fence lines, parking lot boundaries, or building perimeters up to 190 feet, triggering the alarm panel when a person breaks both beams\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDriveway and gate entry detection\u003c\/strong\u003e where the beam sensor detects vehicles or pedestrians crossing a driveway or approaching a gate, providing an early warning zone before someone reaches the building entrance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndoor warehouse and restricted area monitoring\u003c\/strong\u003e where the extended 390-foot indoor range covers long hallways, loading docks, or warehouse aisles, and the twin-beam design avoids false alarms from forklifts passing through adjacent zones\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat the E-960-D190Q Delivers\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e190 ft outdoor \/ 390 ft indoor detection range:\u003c\/strong\u003e Covers long perimeter runs with a single transmitter-receiver pair.

When a person or object breaks the beam, the receiver detects the interruption and sends an alarm signal to the connected security panel. Twin-beam models like the E-960-D190Q require both beams to be broken at the same time, which significantly reduces false alarms caused by small animals, debris, or weather. Photoelectric beam sensors are used for outdoor perimeter protection, driveway detection, and indoor restricted-area monitoring where motion detectors would be impractical due to range or environmental conditions.\u003c\/p\u003e","brand":"SECO-LARM","offers":[{"title":"Default Title","offer_id":50706785501368,"sku":"E-960-D190Q","price":122.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/9110\/4952\/files\/Screen_Shot_2025-04-04_at_7.37.28_AM.png?v=1743777465","url":"https:\/\/islandelectricalsupply.com\/products\/seco-larm-e-960-d190q-photoelectric-beam-sensor","provider":"Island Electrical Supply","version":"1.0","type":"link"}
