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
measured from the screw surface of the base jaw in the direction of the main axis. Failure to comply with the max. permissible finger length will result in increased wear.

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
When gripping, the speed must be adapted as described in the operating manual so that the closing and opening times can increase. The times specified are only the movement times of the base jaws at max. speed, max. acceleration without electrical restrictions, and observance of the maximum permissible masses per finger.

Motor torque
Required motor torque may be permanently applied to achieve the maximum gripping force.

Operating principle
Spindle drive

Housing material
Aluminum alloy, coated

Base jaw material
hard-anodized, high strength aluminum

Actuation
electrically via an adaptable servo drive

Warranty
24 months

Scope of delivery
Enclosed pack with centering sleeve and centering pins, assembly and operating manual with declaration of incorporation.
Depending on the variant, operation of the gripper requires a motor add-on kit, a servomotor, and a suitable controller. They are not included in the scope of delivery and must be ordered separately.
