Description
SMA PCB Connector | Through Hole | Brass Body | Bulkhead
The ROSNOL SMA2IA50-1580A/91 is a high-performance SMA plug (male) connector designed for bulkhead coaxial PCB applications. Featuring a screw-lock coupling mechanism and through-hole mounting, it supports frequencies from 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 and fastening nut for secure panel integration.Constructed with a beryllium copper center contact and brass body, both gold-plated over non-magnetic nickel-phosphorus underlayers, the SMA2IA50-1580A/91 ensures excellent conductivity and durability. The PTFE insulator provides thermal stability from -65°C to +165°C. Rated for ≥ 500 mating cycles and RoHS compliant, it offers reliable performance in demanding RF environments.
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.
