This is an incremental rotary encoder that uses contactless magnetic sensing to detect rotational speed and direction. The two Hall Effect sensors measure the 66-pole ring magnet and output two signals in quadrature. This automotive-qualified solution is a low-cost and far more reliable alternative to conventional mechanical contact-based encoders, as it uses solid-state sensing that is immune to physical wear, dirt, corrosion, and RF noise.
