Description

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.

Features
  • Extremely simple, reliable, and low-cost
  • Greater design flexibility and ESD immunity, over mechanical encoder modules
  • 66-pole magnet provides 132 detections per 360° of rotation (1 per 2.7°)
  • >20kHz Hall Effect sensor bandwidth provides low 15µs latency
  • Digital sensing and digital signaling offer noise immunity
  • Automotive qualified to AEC-Q100
