Frequently Asked Questions
Are these connectors compatible with 50-ohm BNC systems?
Yes. The 31-315-RFX is a 50-ohm connector suitable for most RF and test applications using RG-174, RG-188, or RG-316 cable.
What type of crimp tool should I use?
Use a standard BNC crimp tool compatible with RG-174/188/316 ferrule sizes (typically 0.128 in hex die).
Do the connectors come individually packaged?
No. These are kept in original Amphenol bulk packaging, six per lot.
Can these be used for video signals?
Yes, they can handle composite or analog video when matched to 50-ohm systems, though 75-ohm connectors are preferred for long video runs.
What is the plating on the center pin?
The center contact is gold-plated for low contact resistance and long-term conductivity stability.
Amphenol built the RFX line for precision and endurance in the RF world — this six-piece lot carries that legacy forward to your next project, where its next story belongs to you.
