BZ

The BZ connector is a high-power blindmate connector with slide-on mating. This originally designated PMA blindmate by Automatic has PTFE dielectric interface, telescoping insulators and wiping outer contacts. BZ blindmate connector applications include GPS navigation systems and antenna connections.

 

The BZ blindmate connector is a mechanically ruggedized blindmate and can handle 6.7 KW to 2 GHz. The BZ's most common use has been in high power EW systems. BZ connectors have an external spring to provide mechanical device for extensive mechanical misalignment of ± .020 radial and .060 axial minimum.
