Description
SSMA Panel Connector | Brass Body | Stub Terminal | Mechanical Captivation
The ROSNOL SSMA2GTA50-1550A/H1 is a high-frequency SSMA jack designed for DC to 18 GHz applications. It incorporates a stub terminal and a 2-hole flange mount with 8.3 mm (.327 inch) spacing, enabling secure soldering and mechanical stability. Mechanical captivation ensures reliable contact retention under axial and radial stress, with torque ratings up to 1.7 Nm and ≥500 mating cycles.The connector features a brass body and phosphor bronze center contact, both plated with 3 µinch gold over 80 µinch non-magnetic nickel-phosphorus underplating. A 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.
