Rugged and simple to calibrate, it performs reliably in the harshest conditions.\u003c\/p\u003e\n\u003cp\u003eAn analog inductive sensor in the nose of the enclosure detects a metal target — an existing bolt head or a device mounted to the shaft, such as 4B's Whirligig® sensor mount. The Milli-Speed operates over a 20–3,600 PPM range and is set to normal running speed by simple magnetic calibration (17 mA); output rises toward 20 mA above normal speed and falls toward 4 mA as speed drops.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLinear 4–20 mA output for belt slip, underspeed, stop-motion, low- and zero-speed detection\u003c\/li\u003e\n\u003cli\u003eTotally sealed for the harshest conditions\u003c\/li\u003e\n\u003cli\u003eSimple magnetic calibration\u003c\/li\u003e\n\u003cli\u003eWide 20–3,600 PPM speed range\u003c\/li\u003e\n\u003cli\u003eWorks with an existing bolt-head target or 4B's Whirligig® mount\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eRelated accessories: Whirligig® shaft sensor mount (WG1-4B-4), Mag-Con™ magnetic connector (MAG2000), SpeedMaster™ calibration tool (SM2).\u003c\/em\u003e\u003c\/p\u003e","brand":"4B Components","offers":[{"title":"Default Title","offer_id":46204114174088,"sku":"MIL8001V4C","price":999.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/3474\/0360\/files\/Milli-Speed-Switch_6ae1e569-70e0-439b-ae13-7ef4555a52ee.jpg?v=1784638758","url":"https:\/\/chandler-adams-llc.myshopify.com\/products\/4b-milli-speed%e2%84%a2-switch-4-20-ma-inductive-speed-sensor","provider":"Chandler Adams LLC","version":"1.0","type":"link"}
