Product details

MCX 75 Ohm Plug for RG-179 — 252103-75

It is a 75 Ohm impedance variant, designed for use with RG-179, 179A, 179B, 187, 187A, Belden 9221, and M17/94-RG179 cables. 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.

Frequently asked questions

What cable is compatible with 252103-75?
