MCX Snap-On Plug for Non-Magnetic Environments
The 919-NM104P-51A: The snap-on fastening gives quick connect-disconnect without tools, and the right-angle cable exit keeps the assembly low-profile against the panel or chassis. Rated for 500 mating cycles, it holds up to repeated field service without degrading signal quality.
Cable Compatibility and Termination Sequence
This plug accepts RG-174, RG-188A, RG-316, LMR-100, and M17/119-RG174 cables. The shield is crimped; the center conductor is soldered.
RF Performance and Impedance Control
The dielectric is a combination of polyoxymethylene (POM) acetal and PTFE — PTFE keeps the loss low at higher frequencies, while POM provides mechanical stability in the crimp zone. The gold-plated center contact on beryllium copper gives low and stable contact resistance across the 500-cycle life. For a 6 GHz link, the right-angle exit introduces a small impedance discontinuity at the bend, but within the MCX interface the mismatch is negligible for most digital and analog signals.
