The adapter to hold the magnet is nylon. This encoder is really overkill-- its 2000 count resolution per turn, and the motor is geared down 40:1, turning the feed screw with 18:1 lead.
The result is a very crazy 14.4 M counts per inch! The pic 18F4331 interrupt handler very happily keeps up with them all though
