CONVUM SGE Series Electric Vacuum Grippers

CONVUM SGE Series Electric Vacuum Grippers

The CONVUM SGE series e-Hand is an electric vacuum gripper with an integrated pump for robotic pick-and-place operations. It generates vacuum without an external compressed air supply and combines suction control with a built-in pressure display and suction confirmation output. Small and medium versions accommodate different vacuum pad connections, while medium versions also offer balloon hand configurations. The DOBOT+ plug-in provides connection setup, status monitoring, and suction and release control for compatible DOBOT CRA and Nova robots.

Product Highlights

  • Integrated Vacuum Generation
    The built-in electric vacuum pump generates suction without an external compressor or separate vacuum source. One M8 cable carries power and control signals to the gripper.

  • Local Vacuum Monitoring
    An integrated pressure sensor and display show vacuum conditions directly on the gripper. An adjustable suction confirmation threshold provides feedback when the configured vacuum level is reached.

  • Flexible Gripping Configurations
    Compatible suction pads can be selected for the workpiece. Medium versions support balloon hand configurations, while optional pad adapters provide multiple suction points.

  • DOBOT+ Control
    The DOBOT+ plug-in supports connection setup and testing, status monitoring, and suction and release commands, providing the basic functions needed for vacuum handling with supported DOBOT robots.

Application

Pick-and-Place Handling
Vacuum pickup and transfer of workpieces using suitable suction pads, with balloon hand configurations and multi-pad adapters available for different workpiece geometries.
