Description
SMA Bulkhead Connector | Screw-Lock | Brass Body
The ROSNOL SMA2FA50-1955A/91 is a straight bulkhead receptacle jack with solder termination and stub terminal. Featuring a screw-lock coupling mechanism and 50 Ω impedance, it supports frequencies up to 18 GHz with low insertion loss and excellent return loss. Its bulkhead mounting and soldered center contact ensure secure and reliable RF connectivity.This connector is constructed with a brass body and beryllium copper center contact, both gold-plated over nickel for optimal conductivity and corrosion resistance. The PTFE insulator provides stable dielectric performance across a wide temperature range.
ROSNOL’s precision-engineered RF connectors offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All Rosnol RF components are precision-manufactured in ISO 9001-certified facilities, and are fully RoHS and REACH compliant, ensuring environmental safety and global regulatory alignment. Customization services for plating, materials, and mechanical design are available upon request.
