The ATS632LSA gear-tooth sensor is an optimized Hall-effect IC/magnet combination that provides 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 and a single-element self-calibrating Hall-effect IC that has been optimized to the magnetic circuit. This small package, with its non-oriented operation, can be easily as sembled on a PC board for complete protection and used in conjunction with a number of gear configurations.
