Description
SMA Jack | Open | With Chain | RF Accessory | Stainless Steel Body
The ROSNOL SMA2AO50-1270A-88.9/9Q is an SMA jack open-type RF accessory designed with an open termination structure at the connector interface. This model provides a nominal impedance of 50 Ω and is specified for operation over a frequency range from DC to 18 GHz. The screw-lock coupling design allows secure mechanical attachment to an SMA plug connector, supporting stable positioning during handling or storage. A stainless steel chain with a length of 88.9 mm is integrated to retain the accessory when removed, helping prevent loss while maintaining controlled positioning.The center contact is manufactured from beryllium copper with gold plating over a nickel underplate. The connector body is made from stainless steel with gold plating over a nickel underplate, offering enhanced corrosion resistance and mechanical robustness. A silicone rubber gasket and passivated stainless steel chain are included to support sealing performance and long-term mechanical durability.
ROSNOL’s RF accessories are designed to complement and protect RF connectors and related components. Manufactured under ISO 9001-certified processes, ROSNOL accessories offer consistent mechanical quality and reliable construction as cost-effective alternatives to products from established European and American brands. All ROSNOL products comply with RoHS and REACH regulations, with customization options available for materials and mechanical design.
