SMB Female Crimp Connector Right Angle Adapter

SMB Crimp Male and Female RF Connectors – High-Performance, Reliable, and Durable for Global Applications

Engineered for precision and reliability in demanding environments, the SMB crimp connector series offers a robust solution for high-frequency signal transmission across telecommunications, industrial electronics, and test & measurement systems. These connectors are designed to meet international standards while delivering consistent performance under extreme conditions—from harsh outdoor installations to sensitive laboratory setups. With options for both male and female configurations, including straight and right-angle variants, this product supports versatile integration into existing PCB layouts or cable assemblies.

Key specifications include an operating temperature range from -55°C to +155°C (with PE cables rated up to +105°C), impedance options of 50Ω or 75Ω, and frequency capabilities reaching up to 4 GHz for 50Ω models and 2 GHz for 75Ω versions. The connectors maintain excellent electrical integrity with low insertion loss—just 0.1 x √f(GHz) dB at 1 GHz—and a voltage standing wave ratio as low as 1.35 at 3 GHz for straight types and 1.45 at 1 GHz for right-angle models. Their durability exceeds 500 mating cycles, ensuring long-term stability in repetitive connection scenarios.

Constructed with precision-machined brass contacts and corrosion-resistant plating, these connectors ensure minimal contact resistance—≤6 mΩ for center pins and ≤1 mΩ for outer shells—while maintaining insulation resistance above 1,000 MΩ. The coupling nut retention force exceeds 180 N, providing secure connections even in high-vibration applications such as automotive systems or aerospace equipment. Additionally, the center conductor retention force is ≥0.28 N, preventing accidental disconnection during handling or operation.

These SMB connectors are ideal for use in wireless communication modules, satellite receivers, medical imaging devices, industrial automation controls, and military-grade instrumentation where signal fidelity and mechanical resilience are critical. Whether deployed in fixed installations or portable field gear, they support seamless data transfer across a wide bandwidth spectrum without compromising on form factor or ease of installation.

Users worldwide have praised the consistency and quality of these connectors, noting their compatibility with standard RG-174 and similar coaxial cables, as well as their ability to reduce signal degradation over time compared to lower-grade alternatives. Many engineers appreciate the straightforward crimping process, which minimizes assembly errors and reduces production downtime in high-volume manufacturing settings.
