Description
The ATS667 is a true zero-speed gear tooth sensor IC consisting of an optimized Hall IC-rare earth pellet configuration in a single overmolded package. The unique IC and package design provides a user-friendly solution for digital gear tooth sensing applications. This small package can be easily assembled and used in conjunction with gears of various shapes and sizes.
