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-calibrat-
ing 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 conjunc-
tion with a number of gear configurations.

PRELIMINARY INFORMATION
(subject to change without notice)
December 2, 1998
The gear sensing technology used for this sensor subassembly is
Hall-effect based. The sensor incorporates a single-element Hall IC
that switches in response to absolute magnetic signals created by a
ferrous target. The digital output is LOW over a tooth and HIGH over a
valley. The sophisticated processing circuitry contains self-calibrating
6-bit A/D circuitry that adapts the thresholds to the peak-to-peak
signals to minimize the effects of variation in application air gap on
switch-point timing accuracy. The effects of system and device offsets
are minimized by using active offset cancellation circuitry. The digital
algorithm provides zero-speed detection capabilities without the
associated running jitter inherent in classical digital solutions.

Information.
This sensor system is ideal for use in gathering speed, position
and profile information of ferrous objects. They are particularly suited
to large tooth/valley sensing applications where accurate timing
accuracy is a desired feature. For applications requiring the sensing of
fine-pitch gears, the ATS610LSA and ATS611LSB are recommended.

*Temperature excursions to 225 °C for 2 minutes or less are permitted.
†All industry-accepted soldering techniques are permitted for these subassemblies provided the indicated
maximum temperature for each component (e.g., sensor face, plastic housing) is not exceeded. Reasonable
dwell times, which do not cause melting of the plastic housing, should be used.
