The kit's end cap and ferrule capture the cable jacket and provide strain relief; the gasket seals the interface against moisture ingress. ## Mating Cycles and Field Service Life The gold-plated center contact (brass) and gold body finish resist fretting corrosion across those cycles. For a field-serviceable connector on test equipment or patch panels, 500 cycles translates to years of daily reconnections before the retention force degrades noticeably. The polyoxymethylene (POM) and PTFE dielectric materials maintain stable impedance across temperature and humidity swings.","metaTitle":"Amphenol 252109-75 MCX Plug, 75 Ohm, 6 GHz, RG-405","metaDescription":"252109-75 MCX plug, male pin, 75 Ohm impedance, 6 GHz max frequency, for RG-405 semi-rigid cable.
