The SCHUNK EGK 40 is an electric gripper for handling small workpieces. With 41.5mm stroke per jaw and a maximum gripping force of 150N, the gripper is versatile. With its weight of 0.97 kg, it can be perfectly used with collaborative robots.

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 SoftGrip gripping modes are available. With BasicGrip and SoftGrip, continuous operation of the motor and thus permanent re-gripping of the workpiece is possible. With BasicGrip, the gripping speed is automatically optimized to the gripping force setting. With SoftGrip, fracture-sensitive workpieces can be gripped particularly gently by reducing the impulse forces to a minimum when they hit the workpiece.

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.

• Smooth-running profile rail guide with stainless steel face seal, food-grade lubrication and cover made of durable polycarbonate.
• Fully integrated and sealed control and power electronics with status LEDs and M8 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 a constantly acting gripping force over the entire finger length, without minimum approach distance.
• Brushless 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.
