The CRG 200 with 200 Newton gripping force can be used in applications for which previous collaborative grippers had too little endurance. The 85-millimeter stroke enables flexible use for various tasks. The CRG 200 is parameterized, controlled and diagnosed via the industry standard IO-Link. This allows the user to permanently monitor the current status of the gripping process and readjust it if necessary. The integrated gripping part detection makes external sensors superfluous and can be flexibly parameterized via IO-Link. For reliable handling throughout the entire process, the CRG 200 has workpiece monitoring as standard; it alerts the system controller if, contrary to expectations, a workpiece is lost.

The CRG 200 also scores points when it comes to gripping force: instead of limiting the motor current to set the gripping force, the Weiss gripper has a model-based sensorless gripping force control that regulates the gripping force precisely and independently of external influences. This means that even workpieces that are otherwise difficult to grip, such as brittle or flexible parts, can be handled reliably. In the event of a power failure, the CRG 200 has a gripping force safety device that permanently maintains the last set gripping force and enables the process to be continued immediately after switching back on.

The CRG 200 was specially developed for collaborative applications and meets the DGUV recommendations for collaborative robot systems as well as the requirements of the ISO/TS 15066 standard as standard and has a safe gripping force limitation. This simplifies the mandatory risk assessment of the system in collaborative robot applications, speeds up engineering and contributes to cost savings. Rounded edges prevent injuries. The integrated anti-glare illuminated ring clearly informs the worker of the current system status.

Permagrip is an HRC-capable gripping force maintenance device that does not snap shut during manual workpiece removal and can therefore also be used safely in direct interaction with humans. To ensure seamless continuation of production after loss of power supply, the CRG 200 has a precise absolute sensor system that determines the finger position without a reference run when switching on.
