The EGP from SCHUNK (Morrisville, NC) is an electric small part gripper that weighs 110 g, and has a stroke of 3 mm per finger. The gripping force can be adjusted on two stages, and its maximum gripping force amounts to 40 N. The gripper can handle workpieces of up to 200 g. Its closing time amounts to 0.09 s. The maintenance-free servomotors are brushless, and are equipped with cross roller guidance, enabling the gripper to be used for pick and place applications.

The mechatronic gripper is based on the platform of the pneumatic MPG-plus small part gripper. Users can transfer the sensor system of the MPG-plus onto the EGP, and existing systems can be changed from pneumatics to electronics. Actuation is done analogous to the MPG-plus digitally directly, or via a sensor distributor. The MPG-plus and the EGP can be screwed on and through laterally and bottom-sided.
