Designed for non-contact detection along a defined path, it is commonly used in automated production lines and conveyors to verify the presence or absence of parts. In a through-beam configuration, an emitter and receiver are aligned so that object interruption of the beam produces a change in the receiver’s output. This model carries the EFECTOR PN4221 designation, identifying its place within SICK’s industrial sensing portfolio.\u003c\/p\u003e\u003c\/div\u003e","brand":"EFECTOR","offers":[{"title":"New","offer_id":51685613601070,"sku":null,"price":218.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_177bfafa-2432-483b-9129-b88d9ef1ba2b.jpg?v=1769725000","url":"https:\/\/plgautomation.com\/products\/sick-ag-pn4221-photoelectric-sensor-through-beam","provider":"PLG Automation ","version":"1.0","type":"link"}
