True Zero Speed
Miniature Gear Tooth Sensor
The ATS645LSH is an optimized Hall effect sensing integrated
circuit and magnet combination that provides a user-friendly
solution for true zero-speed digital gear-tooth sensing in two-wire
applications. The sensor consists of a single-shot molded plastic
package that includes a samarium cobalt magnet, a pole piece, and
a Hall effect 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.
The integrated circuit incorporates a dual element Hall effect
sensor and signal processing that switches in response to
differential magnetic signals created by ferrous gear teeth. The
circuitry contains a sophisticated digital circuit to eliminate magnet
and system offsets and to achieve true zero speed operation (ref
U.S. Patent 5,917,320). A-D and D-A converters are used to adjust
the device gain at power up and to allow air gap independent
switching.
The regulated current output is configured for two wire
applications and the sensor is ideally suited for obtaining speed and
duty cycle in ABS and transmission application gear-tooth-based
configurations.
