Hockey Puck rotary encoder is non-contact to the measuring surface and compensates for mechanical misalignment. It has no shaft or bearings so drag, endplay, corrosion, side loading, and push-out problems are eliminated. Magnet mounted on the rotating object locates the encoder close by. Precise mounting is not required, as it tolerates changes in distance, centering, and planer tilt. Non-contact means vibration and shock from mechanics are not transmitted directly to the electronics in the encoder.
