SUBASSEMBLY
ATS632LSC
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 ex-
tremely 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.

PRELIMINARY INFORMATION

April 8, 1998
ABSOLUTE MAXIMUM RATINGS
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.
The sensor system is ideal for use in gathering speed, position and
profile information of ferrous objects. The device is 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 ATS611LSB is recommended.
