Product details

BNC Dust Cap for Jack Protection

The Amphenol RF 202100-10 is a BNC cap (cover) designed to protect unused BNC jacks from dust, debris, and physical damage when the interface is not mated. The brass body carries a nickel finish that resists corrosion and maintains RF shielding continuity across the connector face. It is the plain-cap variant of the series — no chain or tether — so it stays on the jack by friction fit alone.

Material and Finish

Machined from brass with a nickel body finish, the 202100-10 cap matches the plating on standard BNC jacks. The nickel layer provides a hard, oxidation-resistant surface that survives repeated install-and-remove cycles on a test panel or field rack without galling.

Frequently asked questions

What is the 202100-10 BNC cap used for?

The 202100-10 is a protective cover (cap) for BNC jacks. It shields the female center contact and dielectric from dust, moisture, and mechanical impact when the jack is not mated, preserving signal integrity for the next connection.

Is 202100-10 compatible with all BNC jacks?

Yes, the 202100-10 fits standard BNC jacks per the BNC interface specification (IEC 60169-8 / MIL-STD-348). The friction-fit design works with both 50-ohm and 75-ohm BNC jacks, though it is electrically passive — no impedance rating applies.

Where can I buy 202100-10?

The 202100-10 is sourced to order through independent interconnect distribution.
