Festo
4788875
Rotary gripper module EHMD-40-RE-GE
The Festo part number 4788875 is an electric rotary actuator and electric gripper featuring size 40 and an infinite rotation angle. This electric parallel gripper utilizes a hybrid stepper motor for rotation and a stepper motor for gripping, delivering a stroke of 5 mm per gripper jaw across a controllable range of 0 mm to 5 mm with two gripper jaws. Position sensing for both turning and gripping is handled by motor encoder systems, with homing executed via an encoder index for turning and a fixed-stop block for gripping.

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
