ATS632LSA  
ZERO-SPEED, SELF-CALIBRATING,  
NON-ORIENTED, HALL-EFFECT GEAR-TOOTH SENSOR  
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.

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  
Pin 1 = Supply  
Pin 2 = Output  
Pin 3 = Test Point  
Pin 4 = Ground  
Dwg. AH-006-2  
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.  
PRELIMINARY INFORMATION  
(subject to change without notice)  
December 2, 1998  
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.
