iC-MHL100
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.
