Description
SMA PCB Connector | Through Hole | Brass Body | Bulkhead
The ROSNOL SMA2IA50-2681A/91 is a precision SMA plug (male) connector designed for bulkhead coaxial PCB applications with solder attachment. It features a screw-lock coupling mechanism and through-hole mounting, supporting DC to 18 GHz with 50 Ω impedance. Electrical performance includes VSWR ≤ 1.15 + 0.015F(GHz), insertion loss ≤ 0.04 × √f(GHz) dB, and insulation resistance ≥ 5 GΩ. The connector includes a silicone gasket, fastening nut, and washer for secure and sealed integration.Built with a beryllium copper center contact and brass body, both gold-plated over non-magnetic nickel-phosphorus underlayers, the SMA2IA50-2681A/91 ensures excellent RF performance and durability. The PTFE insulator and IP67 rating provide environmental protection across -65°C to +165°C. RoHS compliant and rated for ≥ 500 mating cycles.
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.
