ZERO-SPEED, SELF-CALIBRATING, NON-ORIENTED, HALL-EFFECT GEAR-TOOTH SENSOR

The ATS632LSC gear-tooth sensor is an optimized Hall-effect IC/magnet combination that provides tooth/valley recognition and extremely accurate tooth edge detection when used with large-pitch targets. The sensor subassembly consists of a high-temperature plastic shell that holds together a compound samarium-cobalt magnet, a single-element self-calibrating Hall-effect IC that has been optimized to the magnetic circuit, and a voltage regulator. This small package, with its non-oriented operation, can be easily assembled and used in conjunction with a number of gear configurations.
