6.6
Speed and position sensor (MiniCoder)
Sample illustration: Toothed wheel
The MiniCoder scans a target wheel (toothed wheel) made from ferromag-
netic material. The magnetic field of the built-in encoder is modulated by the
moving target wheel.
q
The sensor detects the change in magnetic field and converts this into a
square-wave output signal (TTL).
q
The sensor multiplies the output signal by 8.
