Description
SMA Plug | Open | With Chain | RF Accessory | Stainless Steel Body
The ROSNOL SMA1AO50-1270A-88.9/9QQ is an SMA plug open-type RF accessory featuring an open termination structure at the connector interface. This component is designed with a nominal impedance of 50 Ω and supports operation over a frequency range from DC to 18 GHz, as specified in the technical data. The screw-lock coupling mechanism enables secure attachment to an SMA jack connector, maintaining stable mechanical positioning during handling or storage. An integrated stainless steel chain with a length of 88.9 mm is included to retain the accessory when not engaged, reducing the risk of loss while keeping it positioned near the connector.The center contact is manufactured from beryllium copper with gold plating over a nickel underplate to provide stable contact geometry and corrosion resistance. The connector body and coupling nut are produced from stainless steel with gold plating over a nickel underplate, supporting mechanical durability and surface stability. A silicone rubber gasket is incorporated to assist sealing and maintain mechanical integrity.
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.
