The snap-on fastening provides quick, secure mating, and the gold-plated beryllium copper body and brass center contact with gold plating ensure low and stable contact resistance over 500 mating cycles. This plug is factory-matched to the cable group listed: RG-179, 179A, 179B, 187, 187A, Belden 9221, and M17/94-RG179. The crimp termination for the shield and the center conductor requires a standard hex crimp tool with the correct die for RG-179-size cable.","metaTitle":"Amphenol RF 252103-75 MCX Plug, 75 Ohm, 6 GHz, Crimp","metaDescription":"Amphenol RF 252103-75 MCX plug, male pin, 75 Ohm impedance, 6 GHz max frequency.
