Electric vacuum gripping instead of pneumatics

The G-VAC generates vacuum electrically directly within the gripper.

Unlike classic vacuum grippers, it requires no compressed air infrastructure.
The gripper is simply electrically controlled using 24 V.

The problem with traditional pneumatic vacuum systems

In most automation systems, vacuum is generated using compressed air. Typical components include compressors, vacuum ejectors, and compressed air lines.

This infrastructure results in:

• High energy costs
• Compressed air network leaks
• High maintenance costs
• High noise levels

A new principle of vacuum generation

The G-VAC utilizes a new method of vacuum generation.

The movement in the gripper is by Shape memory actuators made of nickel-titanium (NiTi) generates.

These so-called Shape Memory Alloy Actuators change their length when electrically activated. This movement is used to generate vacuum within the gripper.

The system requires only:

• a control signal
• a 24-V power supply

The possibilities of this new drive principle

The elimination of pneumatics fundamentally changes the design of a gripping solution.

Elimination of the compressed air system

The gripper only requires an electrical supply. Compressors, Venturi nozzles, and compressed air lines are no longer needed.

Negligible energy consumption

Energy is only required during suction and release. No energy is consumed in the holding state.

High operational reliability

The simple design reduces wear and sources of error.

Compact design

Eliminating pneumatics, gearboxes, and pumps allows for very lightweight and compact grippers.
