Key Specifications
Description
SMA Jack (Female) Bulkhead Cable Connector for RG 402, DC - 18 GHz, VSWR ≤ 1.25, 50 Ω, with Soldered Cable Entry.
The ROSNOL SMA2EA50-0141C/9Q is a high-performance SMA straight bulkhead cable jack optimized for 50Ω impedance and frequencies up to 18 GHz. It features a screw-lock coupling mechanism and a soldered cable entry, with a centre contact that supports both soldered and crimped configurations. The connector delivers consistent RF performance with VSWR ≤ 1.25 (≥ 19.1 dB) and insertion loss ≤ 0.04 × √F (GHz) dB. Supported cable types include RSR 141, RSF 141, RSF141-FEP, RSF141-PVC, RG 402, EF 402 , Belden-1673A and Belden-1673J.
Constructed with a stainless steel body, fastening nut, and washer—all gold-plated over nickel—the connector ensures mechanical strength and long-term reliability. The centre contact is made of beryllium copper with gold plating, while the insulator is PTFE and the gasket is silicone rubber. It is designed to perform reliably in environments ranging from -65°C to +165°C.
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.
