As part of Rockwell Automation's 808 speed sensing lineup, it functions as an electromechanical speed switch used for speed sensing, direction-of-rotation indication, and plugging\/anti-plugging control in motor and drive circuits. The device relies on magnetic coupling technology to sense shaft speed and translate it into a switch output without complex electronics. The 808 family uses this sensing method to generate a discrete contact signal that can feed control logic, relays, or interlock circuits. The 808C3 shares the same sensing principle and electrical interface that characterizes Allen-Bradley 808 Speed Switches, delivering reliable mechanical speed signaling for automation sequences. Typical applications include signaling a controller at a speed threshold, interlocking safety circuits with rotating equipment, and coordinating start\/stop logic in conveyors, fans, and similar machinery where monitoring a defined speed is important.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657440395566,"sku":null,"price":1274.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_5e247b9c-9f5b-4427-9991-71c5bd94188a.jpg?v=1769468993","url":"https:\/\/plgautomation.com\/products\/allen-bradley-808c3-speed-switch-interrupter","provider":"PLG Automation ","version":"1.0","type":"link"}
