BNC Plug (Male) Protective Cap with 150mm Chain

BNC Protective Cap Plug with Chain | Bayonet‑Lock | ROSNOL RF Connector Accessory

The ROSNOL BNC1A00‑1800A‑150/‑‑4 is a BNC straight protective cap plug with chain, designed to protect unmated BNC RF connectors from mechanical damage and environmental exposure. This protective cap utilizes a bayonet‑lock coupling mechanism to ensure secure attachment during handling and storage. The coupling nut is made from brass with copper‑tin‑zinc alloy construction, offering enhanced durability and corrosion resistance, while the silicone rubber gasket improves sealing performance. A metal retaining chain with an approximate length of 150 mm is provided to prevent loss of the cap during installation or maintenance. The protective cap operates over a temperature range from −65°C to +165°C and is RoHS compliant.

This BNC protective cap with chain is intended for RF and microwave systems where reliable connector protection and retention are required. By shielding the connector interface from dust and moisture and keeping the cap attached via the chain, it helps maintain long‑term connector reliability and electrical stability. Common applications include communication infrastructure, laboratory equipment, and RF installations using BNC interfaces.
