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
