General notes about the series

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

Repeat accuracy (gripping)
defined as the spread of the actual position during 100 consecutive closing or opening movements on a rigid workpiece or a fixed workpiece stop under constant conditions.

Repeat accuracy (positioning, unidirectional)
defined as the spread of the actual position per base jaw during 100 consecutive movements to a target position from the same direction under constant conditions.

Repeat accuracy (positioning, bi-directional)
defined as the distribution of the actual position per base jaw during 100 consecutive movements to a target position from both directions under constant conditions.

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

Positioning accuracy
is defined as the deviation of the actual position per jaw during 100 consecutive, unidirectional positioning movements to a defined position under constant conditions.

Closing and opening times (positioning)
Closing and opening times are only the movement times of the fingers at max. speed, as well as max. acceleration with observance of the max. permissible mass per finger and refer to the traverse path per jaw and 50% of the nominal stroke.

Max. speed (positioning) and max. acceleration
is the arithmetic sum of the velocity and acceleration acting on each jaw.

Housing material
Aluminum alloy, anodized

Base jaw material
hard-anodized, high strength aluminum

Warranty
