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.
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.
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.

Threaded vacuum pad connections apply to vacuum pad versions. Additional pads, adapters, and mounting accessories change the installed mass.
CONVUM specifies a maximum continuous suction period of 10 minutes, followed by a non-suction period at least as long as the suction period, corresponding to a duty cycle of 50% or less.
