The Model 770 is an incremental rotary encoder designed for direct mounting on NEMA C-Face motors, featuring a 1.00-inch depth and a thru-bore design compatible with NEMA sizes 56C through 184C. It has an all-metal housing, precision bearings, and an internal flex mount to mitigate shaft runout and axial endplay effects. Supported resolutions range up to 4096 CPR, with quadrature output signals and an index pulse per revolution. Electrical inputs operate from 4.75 to 28 VDC depending on temperature, with output types including open collector, pull-up, push-pull, and line driver. The encoder meets IP65 sealing with the A housing and gasket kit, and IP50 with the B housing. It is rated for 6000 RPM maximum shaft speed, 10 g vibration at 58 to 500 Hz, and operates between 0°C and 100°C. Noise immunity complies with BS EN61000-4-2, IEC801-3, BS EN61000-4-4, DDENV 50141, DDENV 50204, BS EN55022, and BS EN61000-6-2.
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 to 184C). The tough, all metal housing resists the vibration and hazards of an industrial environment.
