Frequently Asked Questions
Which cable types fit the Amphenol 31-321-10RFX plug?
This connector is sized specifically for Belden 8281 and Belden 88281 coaxial cable. Cable jacket and dielectric dimensions differ across coaxial lines, so use with other cable types is not recommended.
What crimp die sizes are required for assembly?
Assembly requires a 0.068-inch (1.7 mm) hex crimp for the center contact pin and a 0.324-inch (8.2 mm) hex crimp for the outer ferrule, matching the Amphenol CTL-2 crimp tool.
Why buy an individual Amphenol BNC plug here instead of chasing a surplus lot?
You get the exact, genuine Amphenol RFX connector needed for your Belden 8281 cable without buying an oversized bulk pack or taking chances on mystery bins. Shipping is $8 flat rate, free once the order passes $28, and orders leave our Idaho warehouse the same or next business day.
A clean crimp on Belden 8281 is one of those satisfying bench jobs where the right connector makes all the difference. Strip your cable, seat the pin, and put that line back in service.
