SMPM is the miniature snap-on interface used where board density or panel space limits the use of standard SMP connectors — common in compact RF modules, test equipment, and airborne electronics where every millimetre of height matters. This kit terminates the cable in the field: the center contact solders to the signal conductor, the ferrule crimps over the braid for shield termination, and the snap-on coupling provides a quick mate with the matching SMPM jack. ## 100 Mating Cycles — Set-and-Forget Duty For a test-port application needing frequent reconnects, the 925-138J-51P offers 500 cycles with a full-detent retention feature — but that jack uses a solder shield termination and is not a direct cable-plug replacement.","metaTitle":"Amphenol 925-129C-51S SMPM Plug Kit, 6 GHz, RG-178/196","metaDescription":"Amphenol SMPM plug kit 925-129C-51S for RG-178/196 coax. 50 Ohm, 6 GHz, snap-on, gold-plated beryllium copper.
