75 Ohm MMCX Plug for RG-179 — Right-Angle Field-Assembly Kit
The Samtec TRUE75™ MMCX7-P-C-GF-RA-CA3 is a 75 Ohm MMCX plug, male pin, for RG-179 coaxial cable. It ships as a 4-piece kit: the connector body, an end cap, a ferrule, and an insulator. The snap-on fastening is standard MMCX — push to mate, pull to disengage — no threads, no torque spec. Gold plating on both the body and the centre contact keeps corrosion off the signal path over repeated connect-disconnect cycles in field service. The beryllium copper body gives the snap ring its spring memory; brass centre contact handles the solder termination.
RG-179 Cable Fit and Termination
This plug is built for RG-179 — a 75 Ohm miniature coax. The kit includes the ferrule and insulator.
Straight vs Right-Angle — Same Series, Different Cable Exit
The closest functional sibling in the TRUE75 MMCX7 line is the MMCX7-P-C-HF-ST-CA3 — same 75 Ohm impedance, same RG-179 cable group, same gold body and snap-on mating. The difference is the cable exit: the -GF-RA-CA3 is right-angle (perpendicular to the mating axis), while the -HF-ST-CA3 is straight (in-line with the mating axis). Choose the right-angle version when the cable needs to run parallel to the panel face; choose the straight version when the cable exits directly away from the mating interface. Both are active, both terminate the same cable, and neither is a direct swap — the orientation is fixed by the body geometry.
