What this MMCX plug is and what it carries
The Hirose MMCX-LP-066(40) is a 50 Ohm MMCX plug with a male pin contact, designed for snap-on mating to any standard MMCX jack. Rated to 6 GHz, it covers the common ISM bands, GPS /L2, and most cellular sub-6 GHz links — the PTFE dielectric keeps the impedance stable across that range.
Termination and assembly — what comes in the kit
This is a solder-contact, crimp-shield termination. The centre pin gets soldered to the coax centre conductor; the shield braid is captured by the crimp ferrule. The package includes two pieces: the connector body and a heat shrink tube. That heat shrink goes over the crimp area to strain-relieve the cable-to-connector junction and seal it against moisture ingress — a detail that saves you sourcing a separate tube for a field-assembled cable.
Mating cycle life and field reliability
Rated for 500 mating cycles, which is typical for an MMCX snap-on interface. The gold-on-gold contact interface (gold centre contact plating, gold body finish) prevents fretting corrosion over those cycles.
