SCT-VFVF-UB-B-V is a 1.85 mm female to 1.85 mm female hermetically sealed bulkhead type coaxial adapter that covers the frequency range from DC to 67 GHz. The bulkhead adapter uses a glass bead and O-ring seal to provide a hermetically sealed RF interface between the vacuum and atmospheric environments. It is ideal for use as a coaxial RF feedthrough for testing in vacuum environments, such as a thermal vacuum chamber. It can also be used for other applications where an airtight vacuum seal is required. The bulkhead configuration gives mounting flexibility for a variety of mounting plates and flanges, such as ConFlat (CF) and KF vacuum flanges. Other configurations are available under different model numbers.
