AEAS-7500 Description

The encoder IC consists of 13 signal photo diode channels and 1 monitor photo diode channel and is used for the optical reading of rotary or linear code carriers (i.e. The photodiodes are acpanied with precision amplifiers plus additional circuitry. The monitor channel is used to drive a constant current source for the highly collimated IR illumination system.

AEAS-7500 Applications

  • Rotary application up to 16 bits / 360° absolute position
  • Cost effective solution for direct integration into OEM systems
