Stepper motor 42BH88EC06IE

48 Vwith integrated driver and codercompact

Product overview
The 42BH88EC06IE is the 0.72 N·m maximum-output-torque option in the 42 mm EtherCAT group. Its integrated motor, drive and encoder arrangement supports cleaner wiring and closed-loop motion feedback in compact, demanding axes.

Key Highlights

• 0.72 N·m maximum output torque
• 9–48 VDC input
• EtherCAT and TTL communication
• 4096-line / 16,384-count encoder feedback
• Internal FLASH configuration storage
