ATS651LSH
Two-Wire Self-Calibrating Differential
Speed and Direction Sensor with Vibration Immunity
The ATS651LSH is a mechatronics component with an integrated Hall-effect sen-
sor and magnet, providing an easy-to-use solution for speed and direction sensing
applications. The solid thermoset molded plastic package contains a samarium
cobalt magnet and a Hall-effect IC optimized to the magnetic circuit. This sensor
module has been designed specifically for high reliability in the harsh automotive
environment.
The IC employs patented algorithms for the special operational requirements of
transmission applications. This two-wire device communicates the speed and
direction of a ferrous target via a pulse width modulation (PWM) output protocol.
The ATS651LSH is particularly adept at handling vibration without sacrificing
maximum air gap capability or creating an erroneous 鈥渄irection鈥?pulse. Even the
higher angular vibration caused by engine cranking is completely rejected by
the device. The advanced vibration detection algorithm systematically calibrates
the sensor on the true rotation signals from the first three and a half teeth, not on
vibration, thus always guaranteeing an accurate signal in running mode.
Patented running mode algorithms also protect against air gap changes, whether
or not the target is in motion. Direction information is always available on the first
magnetic edge after a direction change. Advanced signal processing and innova-
tive algorithms make the ATS651LSH an ideal solution for a wide range of speed
and direction sensing needs.
