Circular Miniature Feedthroughs available from Allectra come in two different versions and enable a high density of contacts over a small space. For a DN16CF Flange, 12- and 19-pin versions are available.
The air side connector is screwed onto thefeedthrough. A comprehensive shielding is provided by an optional metal housing that includes strain relief. On the vacuum side, a PEEK connector with crimp-pins is mounted. It is also possible to solder the pins.

Complete System: Air side connector, feedthrough, vacuum side connector with metal housing and strain relief shown with a shielded in-vacuum cable.
These feedthroughs are provided not only on KF25 and CF16 flanges and their bigger variants but also on custom and ISO-K flanges. Also available are weldable versions with 21.2 mm ø. It is feasible to mount CM feedthroughs in combination with other types (high voltage, coaxial, etc.).
