Product description

The iC-MHL100 is a magnetic position sensor with integrated Hall sensors for the scanning of magnetic tapes and pole wheels featuring a pole pitch of 1 mm. Moving speeds of up to 4 m/s can be followed even at highest resolution representing 0.49 µm.
The signal conditioning unit generates constant-amplitude sine and cosine voltages that are used for real-time tracking sine-to-digital angle conversion.
The resolution can be programmed up to a maximum of 4096 increments within one magnetic period of 2 mm.

Features

  • Absolute position within the magnetic period of 2 mm
  • 12-bit interpolation w. 4096 increments, resolution better 0.5 µm
  • Alternative to AMS AS5311
  • Realtime system for linear speed up to 4 m/s at full resolution
  • Automatic signal offset compensation
  • Automatic amplitude control for optimum operating point
  • Programmable features: interpolation factor, hysteresis, minimum phase distance, zero position and code direction
  • Electronic index generation with multi-purpose enable input
  • RS422-compatible A/B/Z outputs for encoder quadrature signals with up to 8 MHz edge rate
  • BiSS/SSI interface for high-speed serial data output (BiSS/SSI) and configuration (BiSS)
  • Zener-Zap ROM for non-volatile setup and OEM data
  • Signal monitoring: loss of signal, excessive frequency
  • Single 5 V supply
  • Extended temperature range of -40 to +125 °C

Applications

  • Motion control
  • Linear position encoders
  • Incremental off-axis rotary encoders
