Why Choose PkZ Products?

The PkZ Microwave contact maintains constant impedance over the industry’s widest axial mating tolerance, allowing the design to overcome typical system tolerance stack-up that disrupts standard contact performance.


Continuous High Performance Whether Fully or Partially Mated!

Impedance changes in a standard SMPM coaxial connector interface as a gap is introduced due to expected mating tolerances.

The unique PkZ design provides constant impedance even as gaps are introduced in the mating interface.
