ATS612JSB TRUE ZERO-SPEED/ HALL-EFFECT ADAPTIVE GEAR-TOOTH SENSOR

The ATS612JSB dynamically coupled gear-tooth sensor system is a Hall IC/magnet configuration that is fully optimized to provide digital detection of gear-tooth edges in a small package size. This device contains selfcalibrating circuitry that nulls out the effect of air gap variations on the switchi.

ATS612JSB DYNAMIC, SELF-CALIBRATING, PEAK-DETECTING, DIFFERENTIAL HALL-EFFECT GEAR-TOOTH SENSOR PRELIMINARY INFORMATION (subject to change without notice) ATS612JSB The ATS612JSB dynamically-coupled gear tooth sensor is a peak detecting device that uses gain control to provide extremely accurate gear edge detection down to low operating speeds. Each sensor subassembly consists of a high-temperature plastic shell that holds together a samarium-cobalt magnet, a pole piece, and a dynamicallycoupl.
