MU27S 25-32N is a magnetic target suitable for the iC-MU. The disc comprises of a two track nonius code with 31 polepairs on the nonius track and 32 polepairs on the master track.
The outer diameter is 24.5 mm. The target is mounted on an aluminum hub. The magnetization is on the outside of the cylinder.
iC-MU is used for magnetic off-axis position detection with integrated Hall sensors. By scanning two separate channels i.e. the master and nonius track, the device can provide an absolute position within one mechanical revolution.
Position data can be transmitted serially (SSI, BiSS, SPI), incrementally, or analog through two ports in various modes of operation. Commutation signals (U/V/W) for brushless DC (BLDC) motors with up to 16 pole pairs are derived from the absolute position.
