The main advantage of the VR series in-line ejectors is that they can be mounted directly on the suction cup, which simplifies wiring.
By integrating the ejector into the suction cup we obtain a localized vacuum and, therefore, the possibility of obtaining multiple independent grips, even in the absence of objects.
It is also possible to supply vacuum to two or more suction cups using a 1/8 Gas or 1/4 Gas T-shaped fitting.
