ZNC
SMC's Bernoulli type grippers, series ZNC moves work pieces without leaving flaws or adsorption marks. The ZNC can be used for the transfer of thin cloths, films, printed circuit boards, bubble wrap, etc.
XT
Non-contact suction cups (XT661) utilize the Bernoulli principle for picking up parts where direct contact is not feasible. The design makes it possible for picking up porous, uneven and serrated surfaced objects.
XT661's design averts deforming or distorting the shape of fragile and non-rigid workpieces such as: foil, thin sheets, paper, and printed circuit boards.
