As a member of SICK’s DFS21A family, it provides quadrature A and B channel outputs to determine rotor position, direction, and speed for closed-loop control in servo drives, robotics, packaging lines, printing presses, and CNC equipment. DFS21A encoders are offered in multiple mechanical configurations, including through hollow-shaft and solid-shaft variants, and with different connector options; the exact mounting footprint, electrical interface, and Pulses Per Revolution (PPR) depend on the specific variant. The KFB prefix indicates a particular DFS21A configuration within the family, so the full part number encodes shaft type, connector, and electrical arrangement; for precise electrical characteristics, mounting dimensions, and available PPR options for this model, consult the official SICK data sheet or a verified distributor listing. Typical use cases include fast, feedback-intensive applications where reliable speed and position data are essential to machine performance, such as conveyor drives, automated assembly cells, and robotics actuators. \u003c\/p\u003e\u003c\/div\u003e","brand":"Sick","offers":[{"title":"New","offer_id":46269183394026,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-019.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/sick-ag-dfs21a-kfbac000698-incremental-encoder","provider":"GTG Hardware","version":"1.0","type":"link"}
