Incremental Thru-Bore & Motor Mount Encoders
The Model 770 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 mounted to this encoder. Unlike many C-Face kit type
encoders, the Model 770 contains precision bearings and an internal flex mount,
virtually eliminating encoder failures and inaccuracies induced by motor shaft runout or
axial endplay. The advanced Opto-ASIC design provides the advanced noise immunity
necessary for many industrial applications. This encoder is ideal for applications using
induction motors and flux vector control. The Model 770 provides speed and position
information for drive feedback in a slim profile—only 1.00" thick. The Thru-Bore 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 - 184C). The
tough, all metal housing resists the vibration and hazards of an industrial environment.
NOTES:
1 Thru-Bore version may be IP65 sealed if mounted between two C-Face devices with optional gasket kit.
Select 'Yes' under C-Face Gasket Kit Option.
2 Contact Customer Service for index gating options.
3 5 to 24 VDC max for high temperature option.
4 Not available with 5-pin M12 connector. Available with 7-pin MS connector only without Index Z.
5 For mating connectors, cables, and cordsets see Encoder Accessories on page 102 or visit
www.encoder.com. For Pin Configuration Diagrams, see page 107 or visit www.encoder.com.
6 For non-standard cable lengths, add a forward slash (/) plus cable length expressed in feet.
Example: P/6 = 6 feet of cable.
