Product details

BNC Cap for Standard Jacks

The Amphenol 031-6 is a BNC cap (cover) designed to protect unmated BNC jacks from dust, debris, and incidental contact. It fits standard BNC jack interfaces — the same bayonet-lock geometry that defines the BNC connector style. The zinc die cast body carries a nickel finish, giving it the familiar silver appearance and corrosion resistance expected on test equipment panels, RF patch bays, and instrumentation racks. A permanently attached chain keeps the cap tethered to the cable or panel so it is not misplaced when the jack is in use.

Frequently asked questions

Does the 031-6 cap fit standard BNC jacks?

Yes. The 031-6 is a BNC cap designed for use with standard BNC jacks. It mates using the same bayonet-lock interface as any BNC plug, so it fits the vast majority of BNC receptacles on test equipment, RF panels, and patch bays.

What is the difference between the 031-6 and the 031-17?

The 031-6 is a plain dust cover. The 031-17 is a shorting cap that grounds the centre contact when installed on a BNC jack. Both are BNC caps with nickel finish and a chain; the 031-6 uses a zinc die cast body, while the 031-17 uses brass.
