Tiny mechatronic wonder accomplishes 3 mm stroke in a record time of 0.03 s

Offering optimal prerequisites for minimal cycle times

10-09-2013 - The mechatronic SCHUNK EGP 25-speed gripper for small components is the smallest electric gripper with integrated electronics on the market, and even more convincing it also has the best stroke to closing time ratio. With a maximum stroke of 3 mm, it only takes 0.03 s for its fingers to close, thus offering optimal prerequisites for minimal cycle times. The tiny, power dense gripper weighs just 100 g and has a gripping force of 7 N. It is suitable for rapid handling of workpieces up to 35 g in friction-fit clamping.


Brushless and thus wear- and maintenance-free servomotors as well as a powerful junction roller guide guarantee a high level of efficiency and make the gripper into a dynamic and high-performance expert for demanding pick & place applications. Since it is based on the platform of the tried and tested pneumatic SCHUNK MPG-plus gripper for small components, it comes with a bundle of additional advantages. In many cases, users can transfer the sensor systems used in the SCHUNK MPG-plus to the SCHUNK EGP-Speed, and easily convert existing systems from pneumatic to electrical operation. Control of the SCHUNK MPG-plus can be analog, digital direct, or via a sensor distributor. Just like the SCHUNK MPG-plus, the SCHUNK EGP-Speed takes screws on the side or at the base, which increases its flexibility within a system design. In order to increase the dynamics and the energy efficiency of higher-level systems, the gripper housing consists of a special high-performance aluminum. In addition, the design is rigorous in eliminating superfluous materials. The electronics are built in the interior to save space. The pick & place expert fulfills protection class IP30 and fits seamlessly in the program for modular high performance assembly from SCHUNK.

SCHUNK's New Safety Gripping System EGN

With the SLS, SOS, and STO functionalities, the SCHUNK EGN gripping system certified in accordance with DIN EN ISO 13849 enables safe human/machine collaboration. If the production process is interrupted by an emergency shut-off, the SCHUNK EGN goes into either a safely limited speed mode or a safe stop mode depending on the activated protection zone. In contrast to other solutions available on the market, the SCHUNK safety gripping system is continuously powered even in the safe operating stop so that the gripped parts are reliably held even without mechanical maintenance of gripping force. As soon as the protection zone is released, the gripper immediately switches back to the regular operating mode without the system having to be restarted.
