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.  
Package SH  
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 “direction” 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.
