The AS5045 is a 12-bit rotary position sensor (previously known as encoder) for absolute angular measurement and with a PWM (=pulse width modulation) output over a full turn of 360° based on contactless magnetic sensor technology. This device fits perfectly for on-axis applications where a simple 2-pole magnet rotates above or below the sensor IC and the zero position can be programmed into the device.

Features

  • Contactless abs. angle position measurement
  • User programmable zero position
  • Diagnostic: Magnet detection and power loss
  • Immune to external magnetic stray fields

Benefits

  • Highest reliability and durability in harsh environments
  • Great flexibility during assembly
  • Operation safety
  • Lower material cost (no magnetic shielding needed)
