General Description

The ATS617 gear-tooth sensor is a peak-detecting device that uses automatic gain control and an integrated capacitor to provide extremely accurate gear edge detection down to low operating speeds.

Each sensor module consists of a high-temperature plastic shell that holds together a samarium-cobalt magnet, a pole piece, and a differential opencollector Hall IC that has been optimized to the magnetic circuit.

This small package can be easily assembled and used in conjunction with a wide variety of gear shapes and sizes.
