Rosenberger MCX 50 Ω coaxial connectors feature a snap-on locking mechanism. They are mainly applied in RF cable connections up to 6 GHz such as those found in fixed and wireless communication systems. MCX connectors offer high reliability, long service life, as well as easy and fast mounting. The PCB connectors are supplied in tape and reel packaging for automatic assembly to boards and in blisters. 

MCX connectors with 75 Ω characteristic impedance are available on request.
