The Amphenol RF 31-219-RFX is a straight BNC-to-BNC adapter, joining two female BNC jacks back-to-back. It is a same-series barrel coupler — use it to extend a cable run, join two cables, or convert a male connector on a panel to a female bulkhead interface. The body is nickel-plated brass, the center contacts are gold-plated phosphor bronze, and the dielectric is PTFE.
The 31-219-RFX is a female-to-female adapter — both ends are BNC jacks with female center sockets. It joins two male BNC connectors or extends a cable run.
The 31-219-RFX is a 50 Ohm adapter, standard for BNC video, telecom, and instrumentation signal paths.
