Product catalog summary

Overview: The 42BH68EC04IE is a 42 mm EtherCAT integrated stepper servo that combines a motor, drive, and encoder feedback into a single compact unit. It supports EtherCAT CoE/CiA 402 motion control, making it suitable for coordinated compact automation axes.

Key Highlights:

42 mm (NEMA 17) frame size with integrated stepper servo.
Operates on a 9–48 VDC input with a maximum output torque of 0.4 N·m.
Features EtherCAT CoE / CiA 402 series capability.
Includes a 4096-line / 16,384-count encoder feedback.
Integration of motor, drive, and encoder in one unit.
