SICK AG DFS21A-KFBAC000698 Incremental Encoder

The SICK DFS21A-KFBAC000698 Incremental Encoder is a compact industrial rotary encoder that delivers incremental position feedback for motion-control systems. 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.
