Description
SMA Male Connector with Solder Cup Terminal | Stainless Steel Body | Epoxy Captivation
The ROSNOL SMA1GTB50-1750A-EC/1XX is a high-performance SMA male connector designed for RF applications requiring secure soldering and mechanical retention. It supports DC to 18 GHz with a 50 Ω impedance and VSWR ≤ 1.30. The connector features a 2-hole flange mount and solder cup terminal with 12.22 mm (0.481 inch) hole spacing. It utilizes a screw-lock coupling mechanism, a soldered center contact, and epoxy captivation. Axial retention is ≥ 27 N and radial retention is ≥ 3 N·cm.The body and coupling nut are stainless steel with passivated finish, while the center contact is brass with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating. PTFE insulator and silicone rubber gasket ensure reliable 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.
