Planar connectors are typically used as a pair or set which is comprised of two connector subassemblies that have a common mating interface. Generally, a pair contains one floatingblind-mate interface with spring loaded inner/outercontacts and the other is a fixed blind-mate inter-face with fixed inner/outer contacts. The Planar Blind-mate series provides threadless connector mating which is useful when mating a narray of connectors on one RF module to anotherarray within seconds. Each connector pair will tolerate typically 0.02 inches per pair radial and axialoffset misalignment and still meet all of its electrical specifications. Please review our Type N Coupling Nut Change
