Device Description
The ATS665 true zero speed gear tooth sensor IC is a Hall IC/
rare earth pellet configuration that is fully optimized to provide
digital detection of gear tooth edges. This device is integrally
molded into a plastic body that has been optimized for size, ease
of assembly, and manufacturability. High operating temperature
materials are used in all aspects of construction.
ATS665LSG
True Zero Speed, High Accuracy, Gear Tooth Sensor IC
Functional Description
Hall Technology
The device contains a single-chip differential Hall effect sensor
IC, a samarium cobalt pellet, and a flat ferrous pole piece. The
Hall IC consists of two Hall elements spaced 2.2 mm apart which
measure the magnetic gradient created by the passing of a ferrous
object. The gradient is converted to an analog voltage that is then
processed to provide a digital output signal.
