The 031-71014-RFX is a 75 Ohm BNC jack connector designed for crimp termination. It is specifically engineered for compatibility with RG-179 and RG-187 coaxial cables. This connector requires a crimp tool using a .068 inch hex cavity for the contact and a .178 inch hex cavity for the outer ferrule. Proper assembly is achieved with the recommended 227-1221-9 die set and CTL-2 series tool. This Type 2 BNC jack provides a reliable solution for high-frequency 75 Ohm interconnections in applications such as video systems and digital signal routing.
