SMCs LEHS, 3-finger electric gripper series, has been designed with a drop prevention function to maintain gripping force on workpieces during an emergency stop or restart. When a teaching box is used, the LEHS is easy to operate with just two parameters, position and thrust, to set *. The LEHS grips cylindrical and spherical, or easily deformed components easily.3-finger type, Possible
The LEHS series electric grippers are equipped with three fingers, offering the ability to hold round work pieces. Four sizes are available. Benefits include adjustable gripping forces, a drop prevention function, and gauging capability for recognizing different dimensions and outputting length measurements.
