Description
SMA Field Replaceable | Screw-Lock | Stainless Steel Body
The ROSNOL SMA1BT50-0018B/9XX is a high-performance SMA Plug (male) connector for field-replaceable use. It supports 50 Ω impedance and operates from DC to 18 GHz with a VSWR ≤ 1.25. Featuring a screw-lock coupling mechanism and 8.98 mm (.354 inch) flange hole spacing, it accepts pin diameters of ∅0.46 [.018]. The connector ensures axial center contact captivation ≥ 27 N and supports ≥ 500 mating cycles for long-term reliability.This connector is built with a passivated stainless steel body and coupling nut. The center contact is made of beryllium copper with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating. PTFE is used for the insulator, and the gasket is silicone rubber. No accessories are specified.
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.
