Description
SSMA Panel Connector | Brass Body | Stub Terminal | Mechanical Captivation
The ROSNOL SSMA2GFA50-1550A/H1 is a high-frequency SSMA jack designed for DC to 18 GHz applications. It features a stub terminal and 4-hole flange mount with 6.5 mm (.254 inch) spacing, allowing secure solder attachment and compact integration. Mechanical captivation of the center contact ensures enhanced stability under vibration and mechanical stress, with ≥500 mating cycles and torque ratings up to 1.7 Nm.Built with a brass body and phosphor bronze center contact, both plated with 3 µinch gold over 80 µinch non-magnetic nickel-phosphorus, this connector delivers excellent conductivity and corrosion resistance. The PTFE insulator supports a broad operating temperature range from −65°C to +165°C. Electrical performance includes ≤1.30 VSWR, ≤0.03√F(GHz) dB insertion loss, ≥5 GΩ insulation resistance, and ≤200 W power handling at 2 GHz.
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.
