Product description

The iC-MH16 12-bit angular encoder is a position sensor with integrated Hall sensors for scanning a permanent magnet.
The resolution can be programmed up to 4096 angular increments per rotation.
The incremental interface with the pins A, B and Z supplies quadrature signals with an edge rate of up to 16 MHz. Interpolation is performed with maximum resolution at a speed of 200 000 rpm.
The commutation interface provides U, V and W signals for commutation of EC motors with up to 16 pole pairs.
