Description
SSMA Panel Connector | Brass Body | Stub Terminal | Mechanical Captivation
The ROSNOL SSMA2GFA50-1470A/91 is a high-frequency SSMA jack designed for DC to 18 GHz applications. It features a stub terminal and 4-hole flange mount with 6.46 mm (.254 inch) spacing, enabling secure solder attachment and compact integration. Mechanical captivation ensures stable contact retention under vibration and torque stress, with ≥500 mating cycles and torque ratings up to 1.7 Nm.Constructed with a brass body and beryllium copper center contact, both plated with 3 µinch gold over 80 µinch non-magnetic nickel-phosphorus, this connector offers excellent conductivity and corrosion resistance. The PTFE insulator supports a wide 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.
