By applying pressure to the opposing drive pistons, the multi-tooth guided base jaws are directly driven via a drive type fastening. The jaw stroke is synchronized by means of rack-and-pinion kinematics. This ensures powerful and centric opening and closing of the gripper.

Gripping force maintenance version AS/IS
Conventional gripping force maintenance via springs also ensures a minimum gripping force in case of a pressure drop. In the AS variant this acts as a closing force, and in the IS variant as an opening force. The image shows the AS variant. The gripping force maintenance can also be used to increase the gripping force or for single actuated gripping.

Gripping force maintenance by means of a pressure spring
Conventional gripping force maintenance via springs also ensures a minimum gripping force in case of a pressure drop. In the AS variant this acts as a closing force, and in the IS variant as an opening force. The image shows the AS variant. The gripping force maintenance can also be used to increase the gripping force or for single actuated gripping.
GripGuard: secure, certified gripping force maintenance version ASC/ISC
Secure GripGuard gripping force maintenance also ensures a permanent min. gripping force of 80%, even in case of a pressure drop. In the ASC variant this acts as a closing force, in the ISC variant as an opening force. Compared to conventional gripping force maintenance via springs, this GripGuard variant thereby ensures a significantly higher gripping force. In addition, the gripping force maintenance is constant over the entire jaw stroke. There is also no risk of injury with this gripper, as the base jaws do not move uncontrollably in the event of pressure drop. This simplifies the risk assessment, since gripping force maintenance is already certified as a safety function (PLd Cat. 3).

Pinion shaft
The one-piece pinion shaft connects the pinion of the jaw synchronization with the mechanics of safe gripping force maintenance. - 8
-
Clamping element
In the event of a pressure drop where a workpiece is not gripped, the clamping element will prevent the pinion from rotating. This prevents any potentially dangerous movements of the gripper fingers. - 9
-
Elastomer
In the event of a pressure drop while gripping the workpiece, the gripping force accumulated in the elastomer (energy storage) will retain the workpiece securely. The clamping element prevents the gripper fingers from opening in such cases. - 10
-
Spring-loaded pneumatic piston
In normal gripper operation, the pneumatic piston is always actuated with compressed air. This does not require a separate air supply. In the event of a malfunction, i.e. a sudden pressure drop, the piston is pushed back via the spring assembly and the clamping element blocks the pinion shaft so that movement of the gripper fingers is no longer possible - 11
-
Pressure compensating valve
The pressure compensation valve ensures any excess pressure that has accumulated inside can escape to the outside. At the same time, it prevents dirt or liquids from entering the inside from the outside.
Certified gripping force maintenance
The certificate was issued by the German Social Accident Insurance (DGUV). The DGUV test certificate confirms the secure GripGuard gripping force maintenance in case of a power failure for the gripper series PGL-plus-P in the versions ASC and ISC. The gripping systems comply with the relevant provisions of Directive 2006/42/EC (Machinery Directive). The safety function is implemented with category 3 and PLd according to EN ISO 13849-1:2015.
Integrated sensor system IOL
The gripper variant "IOL" with integrated sensor system enables precise and process-reliable monitoring of the complete gripper stroke via IO-Link. There is no longer any need for separate procurement, installation and adjustment of additional, externally mounted sensors. In addition to IO-Link standards such as temperature display and process parameters, this integrated sensor system offers two additional modes as standard that are perfectly tailored to gripping applications: Gripping Point Mode and Gripping Range Mode. Up to eight workpieces (positions or ranges) can be stored directly in the sensor profile. Tolerance and hysteresis values are already stored in the sensor profile, but can be set individually if required. However, due to the default values, this is not necessary in most cases.
External sensor system with magnetic switches
For monitoring with magnetic switches, the gripper is equipped with two sensor slots. There is a choice of different sensors: 1-point switches, 2-point switches or else compact analog sensors for mounting in the C-slot. The image shows the "gripper open" and "gripper closed" position query with two MMS 22 sensors.
Sistema de sensores externo con interruptores de proximidad inductivos
La variante de pinza "IN" se suministra con el juego de montaje premontado para dos interruptores de proximidad inductivos. Las posiciones «pinza abierta» y «pinza cerrada» están configuradas por defecto. Los interruptores de proximidad han de solicitarse por separado y vienen colocados en la carcasa hasta el tope y sujetos. Ambos sensores se pueden ajustar de forma individual para supervisar cualquier otra posición, como la de «pieza agarrada», por ejemplo. De manera opcional, se puede insertar otro juego de montaje para dos interruptores de proximidad inductivos adicionales en la parte posterior de la pinza, de modo que se pueden montar hasta un total de cuatro sensores.
Versión de precisión P
En la versión de precisión P de la pinza, las mordazas base se vuelven a montar en la pinza totalmente montada. Como resultado, se pueden compensar las desviaciones relacionadas con la tolerancia y se pueden conseguir las tolerancias de posición, forma y ubicación más precisas. Esto permite conseguir aplicaciones de agarre muy precisas o cambios de posición adecuados de las pinzas sin necesidad de reajustarlas.
Opciones de montaje para complementos personalizados
En la parte superior de la pinza hay cuatro roscas y ajustes disponibles. Si es necesario, se pueden utilizar para fijar estructuras personalizadas o incluir funciones adicionales. La imagen muestra un ejemplo de una estructura con centrado o soporte adicional de una pieza.
Opciones de centraje y montaje para el montaje de la pinza
La pinza puede montarse en dos laterales y en cuatro direcciones de atornillado. Esto permite una fijación universal y flexible de la pinza en todas las disposiciones imaginables.
Conexiones neumáticas para el suministro de energía
La pinza se puede alimentar de forma flexible con aire comprimido por tres lados.

Application example
Application example
In addition to ordinary handling processes, the robust and dirt-protected universal gripper PGL-plus-P can also be used to hold workpieces during simple machining operations. In the example shown, a workpiece is being held between the gripper fingers. A robot moves the workpiece along a stationary deburring spindle for deburring. The connected air purge prevents dirt from entering the gripper.
