The device is listed by SICK with the model HE18-P4A7BB and device type 2084168 (SICK-ID-No. 2084168), confirming the exact part in the HE18 family. It operates on 10-30 VDC, aligning with typical industrial power supplies. Through-beam sensors like this require precise emitter–receiver alignment to maintain robust detection and minimize false triggers, especially in environments with dust, ambient light, or variable targets.\u003c\/p\u003e\u003c\/div\u003e","brand":"Sick","offers":[{"title":"New","offer_id":46269187391722,"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-he18-p4a7bb-photoelectric-sensor-through-beam","provider":"GTG Hardware","version":"1.0","type":"link"}
