ATS645LSH Datasheet (Allegro MicroSystems) - True Zero Speed Miniature Gear Tooth Sensor

ATS645LSH, True Zero Speed Miniature Gear Tooth Sensor

The components in speed sensing applications continue to diminish in size to meet spatial constraints and weight reduction requirements.

As the geometries of gears become smaller, this can compromise the capabilities of a gear speed sensor.

The ATS645 Hall-element-to-Hall-element spacing of only 1.5
