It comes in a housing measuring 30.4 mm wide, 53 mm high, and 80 mm deep, with a light spot of 3 x 9 mm and a standard KV 418 receiving filter to suppress background luminescence. The device operates from 12–30 V DC, drawing less than 60 mA, and offers a switching frequency of 1.5 kHz with a fast 350 µs response time. Output is a light-switching type configurable for either PNP or NPN drive, with HIGH defined as VS– (≤ 3 V) and LOW near 0 V, and it supports up to 8 A in circuits protected against short circuits. Ripple is \u0026lt; 2 Vpp, and the current device delivers an average service life of up to 100,000 hours at +25°C. Adjustment is via a front-end potentiometer, and the receiver responds to signals within a 450–750 nm range, while the emission uses 375 nm light to excite luminescent materials. This LUT3-820 is suitable for automation tasks that rely on detecting luminescent signals under UV illumination, offering a robust, compact solution with clear electrical and optical specifications. \u003c\/p\u003e\u003c\/div\u003e","brand":"SICK","offers":[{"title":"New","offer_id":46269192044778,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-019.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/sick-lut3-820-through-beam-photoelectric-sensor","provider":"GTG Hardware","version":"1.0","type":"link"}
