It features a Ø12 x 50 mm stainless-steel housing with a non-flush mounting and a PA 12 sensing face, delivering a 4 mm nominal sensing distance with an assured distance Sa of 3.2 mm and an effective distance Sr of 4.0 mm. The sensor uses a 4-pin M12x1 connector for DC power and a normally open output, operating from 10 to 30 V DC with polarity reversal protection and short-circuit protection. It is rated IP68 for robust protection against dust and immersion in water, and it can switch up to 2,500 Hz while drawing about 130 mA under load. Ambient operating temperature ranges from -25 to 70 °C, making it suitable for demanding industrial environments. Certifications include CE, cULus, and EAC, reflecting broad interoperability with standard control systems. Applications include metal presence sensing on conveyors, automated assembly lines, and robotic grippers where a compact, corrosion-resistant sensor must reliably detect metal targets without physical contact. \u003c\/p\u003e\u003c\/div\u003e","brand":"Balluff","offers":[{"title":"New","offer_id":51676458647854,"sku":null,"price":29.0,"currency_code":"USD","in_stock":true},{"title":"Used Surplus - Excellent Condition","offer_id":51676458680622,"sku":null,"price":62.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_2d20f56f-25e4-43a6-8568-3d3ba5630619.jpg?v=1769551489","url":"https:\/\/plgautomation.com\/products\/balluff-bes-516-209-sa-1-s21-e-inductive-proximity-sensor","provider":"PLG Automation ","version":"1.0","type":"link"}
