The SCHUNK EGU 70 is an electric gripper for handling various workpieces. With 60mm stroke per jaw and a maximum gripping force of 1950N, the gripper is versatile and, thanks to its robust design, also ideally suited for rough conditions. The large and freely programmable jaw stroke and the stepless gripping force adjustment ensure flexible workpiece handling.

Function

The highest level of functionality is available to you, thanks to the components embedded in the gripper. For example, the gripper fingers can be pre-positioned at high speed or for dipping in a workpiece carrier. The gripping force can be infinitely adjusted to the workpiece handling requirements. Workpiece recognition provides full process transparency for the user. In an emergency stop situation, workpiece loss can be avoided by the integrated gripping force retention.

BasicGrip and StrongGrip gripping modes are available. With BasicGrip, continuous operation of the motor and thus permanent re-gripping of the workpiece is possible. The gripping speed is automatically optimized to the gripping force setting. With StrongGrip, the maximum gripping force is generated and then stored by the gripping force retention. Permanent re-gripping is possible within an adjustable time window.

Connectivity

A wide range of available communication interfaces simplifies dealing with the variety of control and robot manufacturers and ensures time savings during integration. Industrial Ethernet (PROFINET, EtherCAT, EtherNet/IP) enables direct integration without additional gateways into the control environment of leading PLC manufacturers on the market. With the Modbus RTU serial interface, the gripper can be connected to the tool flange of leading robot manufacturers without external cable routing. IO-Link is independent and offers flexibility in connecting to further networks.

• Load-bearing and resistant T-slot sliding guide for large finger lengths, external forces and torques. Optionally available as dust-tight version.
• Fully integrated and sealed control and power electronics with status LEDs and M12 connectors for connecting power supply and communication.
• High-resolution, output-side absolute encoder for precise positioning of the gripper jaws with permanent absolute position feedback.
• Sealed drive train with spur gear and pinion-rack principle for an almost constant gripping force over the entire finger length, with no minimum approach distance.
• Brushless flat motor for limited space and high torques thanks to externally mounted rotor.
• Electromagnetic brake with additional mechanism for maintaining gripping force and position during standstill or power failure.
