Description
SMA Bulkhead Connector | Screw-Lock | Brass Body
The ROSNOL SMA1FB59-2190A/111 is a straight bulkhead plug connector designed for high-frequency RF applications up to 18 GHz. Featuring a screw-lock coupling mechanism and solder cup terminal, this 50-ohm connector ensures secure mating and low insertion loss. Its solder attachment and bulkhead mounting style make it ideal for panel integration in precision RF systems.The connector is constructed with a brass body, coupling nut, fastening nut, and washer, all plated with 3 µinch gold over 80 µinch non-magnetic nickel-phosphorus underplating. The center contact is brass with identical plating, and the insulator is PTFE. A silicone rubber gasket provides environmental sealing, ensuring performance across a temperature range of -65°C to +165°C.
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.
