ATS665LSG

TRUE ZERO-SPEED GEAR TOOTH SENSOR

SENSOR DESCRIPTION

Assembly Description:

The ATS665 true zero speed gear tooth sensor is a Hall IC/magnet configuration that is fully optimized to provide digital

detection of gear tooth edges. This sensor 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.

Sensing Technology:

The gear tooth sensor sub-assembly contains a single-chip differential Hall effect sensor IC, a Samarium Cobalt magnet,

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.
