Product description

The iC-MH 12-bit angular encoder is a position sensor with integrated Hall sensors for scanning a permanent magnet.
The resolution can be programmed up to a maximum of 4096 angular increments per rotation.
The integrated BiSS Interface also enables the position data of several networked sensors to be read out.
The incremental interface with the pins A, B and Z supplies quadrature signals with an edge rate of up to 8 MHz.


Features

  • Real-time system for rotation speed of up to 120 000 rpm
  • Integrated Hall sensors with automatic offset compensation
  • 4x sensor arrangement for fault-tolerant adjustment
  • Amplitude control for optimum operating point
  • Interpolator with 4096 angular increments/resolution better than 0.1°
  • Programmable resolution, hysteresis, edge spacing, zero position and rotating direction
  • Incremental output of sensor position of up to 8 MHz edge rate
  • RS422-compatible AB encoder signals with index Z
  • UVW commutation signals for EC motor applications
  • BiSS interface for data output and configuration
  • SSI-compatible output mode
  • Integrated ZAP diodes for module setup and OEM data, programmable via BiSS interface
  • Signal error (e.g. magnet loss) can be read out via BiSS interface
  • Extended temperature range from -40 to +125 °C
