Product overview
5.1
Function
The gripper has an integrated servo motor. The gripper mechanism converts the
rotary motion of the servo motor into a linear motion of the gripper jaws.
The gripper jaws move towards one another (closing) or apart (opening). Gripper
fingers are fastened to the gripper jaws.
The payload can be gripped in 2 ways:
–
on the external contour (external gripping) when closing
–
on the internal contour (internal gripping) when opening
The parallel gripper is controlled via an IO-Link interface.
