Individually configurable stroke
The stroke per jaw can be configured to customer specifications between 100 mm and 400 mm per jaw with millimeter precision. (For size 10, the stroke is limited to 300 mm)

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.

-
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.

Blocage de la position
Le frein de maintien électrique empêche le mouvement de la vis à billes, maintenant ainsi la position des mors de base. Deux freins sont nécessaires pour la version asynchrone. Un module à commutation rapide (ROBA®-brake-checker) est nécessaire pour chaque frein de maintien (ROBA-stop®). Il est inclus dans l'étendue de la livraison de la pince.

Possibilités de fixation latérale
Option de montage sur la pince pour des éléments supplémentaires tels que caméra, répartiteur ou buse de soufflage. Cette option ne peut pas être combinée avec l'option « conception optimisée du poids ».

Optimisation du poids
Les évidements dans les parois latérales réduisent le poids de la pince jusqu'à 15 %. Cette option ne peut être combinée avec l'option « possibilités de fixation latérales ».

Découpes pour réduire le poids
Capots
Les couvercles ferment la pince du côté de l'attache. Elle est ainsi protégée des influences extérieures à ce stade. Les raccordements du moteur sont coupés en conséquence.

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.
