It provides a PNP switching output through a 4-pin M12 connector and operates on a 10–30 V DC supply, making it compatible with common industrial control circuits. Built for demanding environments, the device is IP67 rated and uses a Class 1 laser for safe operation. A dual-lens system supports reliable sensing with a reflector while enabling optimized minimum-distance performance, and it offers light\/dark switching with teach-in adjustment for quick setup. The VL18L-4P324’s cylindrical form factor and rugged construction suit space-constrained installations on conveyors, packaging lines, and other automated systems where retroreflective sensing of reflective labels, cards, or metal parts is required. Typical applications include parts-present\/absent detection on conveyors, pallet or stack detection in sorting lines, and packaging verification where a retroreflective target is used to generate a stable return signal.\u003c\/p\u003e\u003c\/div\u003e","brand":"SICK","offers":[{"title":"New","offer_id":46282978459882,"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-020.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/sick-vl18l-4p324-retroreflective-photoelectric-sensor","provider":"GTG Hardware","version":"1.0","type":"link"}
