Cordless Soft Palm

Plug-in Soft Palm with a dedicated controller


● No problems about stress on objects that is common in conventional vacuum clamping methods because the clamping force is distributed equally.
● Clamp an object that has an uneven surface.
● Dust never sticks to an object, since the voltage of the back of it is very low,.
● Cordless, small and portable
