It offers an 8 mm typical sensing range, a 3-wire DC output in normally open configuration (output type can be NPN or PNP depending on variant, commonly NPN NO), and a 4-pin micro Quick-Disconnect connection powered by 10–30 V DC. The 18 mm threaded cylindrical housing is IP67 protected for industrial dust and water exposure, and the unit includes LED indicators for power and output status with a high switching frequency for rapid detection. Typical applications include metal object detection and presence\/position feedback in manufacturing automation, conveyor systems, packaging machinery, assembly lines, robotic cells, and material handling equipment; common replacements listed are Allen-Bradley 871TM-B8CP18-A2, Pepperl+Fuchs NBB8-18GM50-E2, and Sick IM18-02BPSZW1.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Surplus Original Box","offer_id":50558363009326,"sku":"Surplus Original Box","price":218.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/871TM-B8C18-A2_1000x1000_08ef1862-620d-478e-9362-51a87d775c93.jpg?v=1752215369","url":"https:\/\/plgautomation.com\/products\/allen-bradley-871tm-b8c18-a2-inductive-proximity-sensor","provider":"PLG Automation ","version":"1.0","type":"link"}
