Epc 771 Model 771 NEMA Motor Mount Accu-Coder

Product Description

The EPC 771 C-Face encoder is a rugged, high-resolution device designed for direct mounting on NEMA C-Face motors, compatible with NEMA Size 182TC to 256TC. Featuring precision bearings and an internal flex mount, it minimizes inaccuracies from motor shaft runout. Its Opto-ASIC design ensures superior noise immunity, making it suitable for industrial applications, including induction motors and flux vector control. The thru-bore design allows simple mounting, and the all-metal housing resists vibration.

• Precision bearings and internal flex mount minimize encoder failures and inaccuracies.
• Designed for direct mounting on NEMA C-Face motors, compatible with NEMA Size 182TC thru 256TC.
