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. The maximum permissible finger length applies until the nominal operating pressure is achieved. With higher pressures, the finger length must be reduced proportionally to the nominal operating pressure.

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
are movement times of the base jaws only, without application-specific gripper fingers. Valve switching times, hose fill times, or PLC reaction times are not included, and are to be considered when cycle times are calculated.

Operating principle
Wedge-hook kinematics

Housing material
Aluminum alloy, anodized

Base jaw material
Steel
