It's used to catch dangerous slow-downs and underspeed on conveyors, bucket elevators, airlocks, mixers, fans, grinders, and many other machines.\u003c\/p\u003e\n\u003cp\u003eAn inductive sensor in the nose of the enclosure detects a metal target — an existing bolt head or a device attached to the shaft. During installation the M300 is calibrated to normal shaft RPM with the supplied magnet, and its internal microprocessor sets the underspeed output to trip at exactly 20% below normal speed, suitable for automatic machine shutdown.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSingle 20%-underspeed trip point\u003c\/li\u003e\n\u003cli\u003eSelf-contained, microprocessor-controlled\u003c\/li\u003e\n\u003cli\u003eSimple magnetic calibration\u003c\/li\u003e\n\u003cli\u003eOutput suitable for automatic shutdown\u003c\/li\u003e\n\u003cli\u003eWorks with a bolt-head target or 4B's Whirligig® mount\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eVersions\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eM3003V10C\u003c\/strong\u003e — 2-wire\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM3005V10CA\u003c\/strong\u003e — 5-wire\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eRelated accessories: 3\/4 in NPT conduit adapter (A34NPT), Whirligig® mount (WG1-4B-4), Mag-Con™ (MAG2000), SpeedMaster™ (SM2), 2-wire load devices (CDL1 110 VAC \/ CDL4 24 VDC).\u003c\/em\u003e\u003c\/p\u003e","brand":"4B Components","offers":[{"title":"2 Wire","offer_id":46204116762760,"sku":"M3003V10C","price":999.99,"currency_code":"USD","in_stock":false},{"title":"5 Wire","offer_id":46204116795528,"sku":"M3005V10CA","price":999.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/3474\/0360\/files\/M300-Slipswitch_21b2d00e-ceda-4da2-b5a6-78b8720508cd.jpg?v=1784638762","url":"https:\/\/chandler-adams-llc.myshopify.com\/products\/4b-m300-slipswitch-inductive-underspeed-sensor","provider":"Chandler Adams LLC","version":"1.0","type":"link"}
