The ATS610LSA and ATS611LSB gear-tooth sensors are opti-
mized Hall IC plus magnet subassemblies that provide a user-friendly
solution for digital gear-tooth sensing applications. Each subassembly
combines in a compact high-temperature plastic package, a samarium-cobalt
magnet, a pole piece, and a differential Hall-effect IC that has been
optimized to the magnetic circuit. These sensors can be easily used in
conjunction with a wide variety of gear or target shapes and sizes.
The ATS610LSA is designed to provide increased immunity to
false switching in applications that require the sensing of large-tooth
gears (e.g., crank angle or cam angle). The ATS611LSB is optimized
to sense fine-pitch gears over large working air gaps (e.g., transmis-
sion or ABS). These sensor subassemblies are ideal for use in
gathering speed, position, and timing information using gear-tooth-based
configurations.
The gear-sensing technology used for these sensor plus magnet
subassemblies is Hall-effect based. The sensor incorporates a
dual-element Hall IC that switches in response to differential magnetic
signals created by the ferrous target. The circuitry contains a patented
track-and-hold peak-detecting circuit to eliminate magnet and system
offset effects. This circuit has the ability to detect relatively fast changes,
such as those caused by gear wobble and eccentricities, and provides
stable operation at extremely low rotation speeds.
