Isolation insert Thermal and electrical isolation of the encoders.
Isolation inserts prevent currents from passing
through the encoder bearings. These currents can
occur when using inverter controlled threephase
or AC vector motors and considerably shorten the
service life of the encoder bearings. In addition the
encoder is thermally isolated as the plastic does not
transfer the heat to the encoder.
