Here is a look back on Allegro’s true zero-speed, high accuracy gear tooth sensor released since 2009. The ATS667 has an optimized robustness against magnetic offset variation and has a small signal ...

The ATS685LSH is an optimized Hall-effect sensing integrated circuit and rare-earth pellet combination that provides a user-friendly solution for true zero-speed digital gear-tooth sensing in two-wire ...

Claimed as suitable for sensing speed and position in fine-pitch targets found in demanding transmission and gear-box applications, the ATS660 is a true zero-speed differential Hall-effect sensor.

A single-chip solution that integrates three highly sensitive Hall elements—a samarium cobalt magnet, a pole piece and a Hall-effect IC—the ATS65OLSH is intended for digital gear-tooth sensing and ...

Designed to operate with True Power-On State (TPOS) recognition, the ATS673/4LSE sensors have a self-calibrating feature in running mode to improve accuracy performance over a wide temperature and air ...

Gear tooth geometry is determined primarily by pitch, depth, and pressure angle. Pitch: Standard pitches are usually whole numbers when measured as diametral pitch P, the ratio of the number of teeth ...
