It operates from a 24 VDC supply and draws about 6 W, with a sensing range of 0.5 to 18 meters, and it features a terminal chamber with a cable gland (PG13.5 thread) for wiring. This receiver, part of the Guardmaster line, pairs with the 440L-T4F0018-Q transmitter to form a complete safety light curtain set that protects a defined zone from unauthorized access. The model number is 440L-R4F0018-Q, and distributor listings note that it was discontinued by the manufacturer around 2010, which can impact current availability and compatibility with newer Guardmaster components. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":46256158343402,"sku":null,"price":109.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-083.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/allen-bradley-r4f0018-q-photoelectric-receiver","provider":"GTG Hardware","version":"1.0","type":"link"}
