General Description

The ATS617 gear-tooth sensor is a peak-detecting device that uses automatic gain control and an integrated capacitor to provide extremely accurate gear edge detection down to low operating speeds.

Each sensor module consists of a high-temperature plastic shell that holds together a samarium-cobalt magnet, a pole piece, and a differential opencollector Hall 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.

Key Features

  • Self-calibrating for tight timing accuracy.
  • First-tooth detection.
  • Immunity to air gap variation and system offsets.
  • Immunity to signature tooth offsets.
  • Integrated capacitor provides analog peak and valley information.
  • Low timing-accuracy drift with temperature changes.
  • Low radiated emissions.
  • Integrated, series resistor on VCC pin for improved transient immunity.
  • Large air gap capability.
  • Small, integrated package.
  • Optimized magnetic circ.
