It measures 18 mm wide by 78 mm long, uses an M18 x 1 threaded housing, and features an axial optical axis. The sensor emits visible red light from an LED source and provides a 4-pin M12 connector with an NPN output option (VL18-4N3640) for 10 to 30 V DC supply. In standard operation it detects objects from 0.05 m to 3 m, with a maximum range to 3.7 m when used with reflector C110A. The light spot is about Ø150 mm at 3 m, and the optical dispersion is approximately 2.8°. With an estimated service life of 100,000 hours at +25 °C, this sensor is suited for automation tasks where a retroreflective configuration is appropriate, such as presence or position sensing along conveyors or equipment runs that incorporate a reflector.\u003c\/p\u003e\u003c\/div\u003e","brand":"SICK","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46282976821482,"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-vl18-4n3640-photoelectric-sensor","provider":"GTG Hardware","version":"1.0","type":"link"}
