Closeup on the encoder mechanics

NewFocus piezoelectric motor
connectors for HV
magnetic proximity switch (contrinex)
2nd switch
Quadrature encoder setup. There's a phase angle between the 2 signals of about 90°.
stainless steel rod
teflon cap
The bracket just clamps to the body of the picomotor.

It works with magnetic proximity switches in a quadrature encoder setup. The mechanical parts were built by our machine shop. Great people !
