The snap-on fastening gives a quick mate and disconnect for field-service or test points where you need to break the line without tools. ## What the 500-cycle rating means on the bench That cycle count puts it in the moderate-duty range — fine for a piece of test equipment or a panel jack that gets reconnected a few times a week over a few years, but not a daily-remate production fixture. ## Termination and shield termination Contact termination is solder; the shield is crimped.","metaTitle":"Amphenol 142221-75 SMB Mini Plug, 75 Ohm, 500 Cycles","metaDescription":"Amphenol 142221-75 SMB mini plug, 75 Ohm, rated 500 mating cycles, -65°C to 165°C.
