The bayonet lock mates fast and the nickel-plated brass body resists corrosion in lab, test, and comms-rack environments. The gold-over-brass centre contact keeps contact resistance stable over those cycles — the nickel body finish handles the wear. ## Crimp vs. Solder: 31-335-RFX vs. 31-320-RFX The sibling 31-320-RFX is the same BNC plug for the same cable group, with the same electrical ratings (4 GHz, 50 Ohm, 500 V). The difference is in the contact termination: the 31-335-RFX is all-crimp (shield and centre), while the 31-320-RFX allows either crimp or solder on the centre contact. If your harness shop prefers soldering the centre pin for a visual inspection point, the 31-320-RFX is the one. For a pure crimp production line, the 31-335-RFX is the correct pick.","metaTitle":"Amphenol 31-335-RFX BNC Plug, RG-58, 4 GHz, 50 Ohm","metaDescription":"Amphenol 31-335-RFX BNC plug, male pin for RG-58 cable. 50 Ohm, 4 GHz, 500 mating cycles.
