The Model 771 C-Face encoder is a rugged, high resolution encoder designed
to mount directly on NEMA C-Face motors. Both sides of the encoder are
C-Face mounts, allowing additional C-Face devices to be easily mounted. Many
competitive C-Face units are kit type encoders, but the Model 771 contains
precision bearings and an internal flex mount that virtually eliminates encoder
failures and inaccuracies induced by motor shaft runout or axial endplay. The
advanced Opto-ASIC design provides superior noise immunity necessary for many
industrial applications. This encoder is ideal for applications using induction motors
and flux vector control. A Thru-Bore design allows fast and simple mounting of
the encoder directly to the accessory shaft or drive shaft of a motor using a NEMA
standard motor face (sizes 182TC - 256TC). The tough, all metal housing resists the
vibration and hazards of an industrial environment.
