BNC Jack (Female) Protective Cap with 150mm Chain

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

The ROSNOL BNC2A00‑1700A‑150/‑4 is a BNC straight protective cap jack with chain, designed to protect unmated BNC female RF connectors from mechanical damage and environmental exposure. This protective cap uses a bayonet‑lock coupling mechanism to ensure secure attachment during handling, storage, and maintenance. The body is manufactured from brass with copper‑tin‑zinc alloy construction, providing enhanced durability and corrosion resistance. A metal retaining chain with an approximate length of 150 mm is included to prevent loss of the cap during field operation. The protective cap supports an operating temperature range from −65°C to +165°C and is fully RoHS compliant.

This BNC protective cap jack with chain is suitable for RF and microwave systems where female BNC connectors are frequently accessed and must remain protected when unmated. The attached chain keeps the cap readily available, reducing the risk of dust or moisture contamination and helping maintain connector interface integrity. Typical applications include RF test equipment, broadcast systems, laboratory instruments, and general‑purpose RF installations.
