DESCRIPTION
The Model ZR C-face encoder for motor feedback is a rugged, high
resolution, high temperature (100°C) encoder designed to mount directly on
NEMA C-face motors. The ZR contains a precision bearing and internal
coupling that virtually eliminates inaccuracies induced by motor shaft runout.
This encoder is ideal for applications using high performance AC vector motors.
The thru-shaft design allows fast and simple mounting of the encoder directly
to the accessory shaft or to the drive shaft of the motor, using the standard motor
face (NEMA sizes 56C, 143TC, 145TC, 182C, 184C). The tough anodized
aluminum housing with thru-shaft design resists the vibration and hazards of an
industrial environment.
