Finger version
The gripper is available in two finger versions. In addition to the basic variant for short finger lengths, a variant with a long finger length can also be configured for corresponding applications.
- 1
-
Short finger length with two guiding carriages per base jaw
- 2
-
Long finger length with four guiding carriages per base jaw
Synchronization
The gripper can be configured as a synchronous and asynchronous variant. In the synchronous variant, the two base jaws are jointly controlled by a servomotor, with the jaw movement being synchronized by a counter-rotating ball screw. With the asynchronous variant, the two base jaws can be controlled independently and separately from each other. In this variant, one base jaw each is connected to one of the two required servomotors via the ball screw and the toothed belt.

Gripper mounting
The gripper offers different options for mounting on robots or gantries.
- 1
-
One-piece adapter plate (gripper side)
- 2
-
Adapter plate, complete (gripper side + blank)
- 3
-
Adapter plate, complete for screw connection according to EN ISO 9409
Position clamping
The electric holding brake prevents the movement of the ball screw, thereby clamping the position of the base jaws. Two brakes are required for the asynchronous variant. One fast switching module (ROBA®-brake-checker) is required for each holding brake (ROBA-stop®). This is included in the scope of delivery of the gripper.

Lateral mounting options
Optional mounting options on the gripper for customized additional attachments such as cameras, sensor distributors or blow-out nozzles. This option cannot be combined with the "weight-optimized design" option.

-
Connection thread for additional attachment

Fit for centering pins
Weight optimization
Cutouts in the sidewalls reduce the weight of the gripper by up to 15%. This option cannot be combined with the option "side mounting options".

Cutouts for weight reduction
Cover plates
The cover plates close the gripper on the attachment side. This protects the gripper from external influences at this point. The motor connections are cut out accordingly.

Bellow
The bellow closes the gripper on the side of the base jaws. It is only available in combination with the cover plate option and it improves the protection of the gripper against environmental influences.
