Vacuum Feedthrough Solution - VFT
Connecting Premium Line positioners mounted in a vacuum chamber to the piezo
controller requires an additional feedthrough solution. attocube’s VFT packages
comprise flanges, electrical feedthroughs, and suitable cabling.

Naming Scheme
In order to better describe the variety of vacuum feedthroughs, attocube uses the following naming scheme, explained here for e.g. the VFT3/NUM/CF63 feedthrough solution:
VFT short for “Vacuum Feed-Through”
/NUM describes the type of output on the electronics and type of positioner con-
nector inside the chamber - in this case positioners with integrated optoelectronic
3 describes the number of cables on the outside and of connectors inside - in this
encoder can be connected (or /RES for resistive encoders)
case one can connect three ANP positioners.
/CF63 is the type and size of flange used (this determines
also the type of connectors and cabling inside).
