Intelligent Monitoring

By continuously monitoring finger movement and gripping force, the WSG series detects contact with the workpiece and monitors it throughout the entire handling cycle. This relieves the system controller of grip-specific functions and eliminates the need for external position switches.

Your benefits at a glance

High process reliability through integrated workpiece detection and continuous grip monitoring
Precise, synchronized finger movement through a high-performance servo drive and belt kinematics
Flexible adaptation to individual applications through integrated Lua scripting
Precise gripping force control for sensitive workpieces with optional force-measuring fingers

Performance meets precision

The grippers of the WSG series combine lightweight construction with long service life and precision. The heart of the gripping modules is a brushless precision drive with an enormous power density. This drives the fingers via belt kinematics, which guarantees the synchronism of the fingers even under difficult conditions.

Adapt the gripper to your application

Do you want to adapt your gripper specifically to your application? No problem, because the WSG series has a powerful script extension with which you can access a variety of internal functions via the Lua programming language. With the script editor integrated in the configuration interface, you can easily write additional programs and save them directly on the gripping module. Special movement profiles can thus be implemented as well as extensions to the command set or the integration of additional sensors in the gripping process. This makes the WSG series a versatile gripping module with an unprecedented level of flexibility.

Precise force control for sensitive grips

For the WSG series, we offer different types of fingers with or without integrated sensors. For example, the WSG-FMF force measuring finger can be used to measure the actual gripping force directly on the gripping part. The measured values are read directly into the control loop of the gripper control via the sensor port and processed there. This enables the gripper to precisely regulate the effective gripping force and enables you to handle even highly sensitive gripping parts safely.
