General notes about the series

Gripping force
is the arithmetic sum of the individual force applied to each jaw at distance P (see illustration).

Finger length
is measured from the reference surface as the distance P in direction to the main axis.

Repeat accuracy
is defined as a distribution of the end Position for 100 consecutive strokes.

Workpiece weight
is calculated for force-fit gripping with a coefficient of static friction of 0.1 and a safety factor of 2 against workpiece slippage at acceleration due to gravity g. For form-fit or capture gripping, there are significantly higher permissible workpiece weights.

Closing and opening times
Minimum closing and opening times are merely the movement times of the base jaws or fingers at max. speed, max. acceleration, without current limitation (maximum current), and observance of the maximum permissible mass per finger.

Nominal currents
can be permanently actuated. With regard to all the currents which are ranging above the nominal current up to the maximum current, the notes of the individual product documentation has to be respected.

Electrical brake
The built-in, electric holding break is used for fixing and holding the position of the gripper jaws in the event of a power failure. It cannot cover all of the security or gripping force maintenance functions.
