Understanding SMA Connectors: A Quick Overview   Kinghelm RF Coaxial Connector, Model KH-SMA-K513-G SMA connectors are compact, threaded RF connectors commonly used in radio frequency applications. They were first developed in the 1960s to provide a reliable connection for coaxial cables. The name "SMA" stands for SubMiniature version A. These connectors are popular due to their small size and excellent performance up to 18 GHz, though some variants can go even higher. Their threaded coupling mechanism ensures a secure and stable connection, reducing signal loss and interference. SMA connectors come in male and female types, with the male having a center pin and external threads. They are widely used in devices like antennas, Wi-Fi equipment, test instruments, and GPS systems. With gold-plated contacts, SMA connectors offer good conductivity and resistance to corrosion. Their versatility and durability make them a standard choice for both professional and consumer RF applicat...

  For procurement managers and design engineers in consumer electronics, the choice between the   XH connector   and the   VH connector   has direct consequences on product reliability, cost, and production efficiency. This article provides an in-depth comparison of construction, performance, use cases, and environmental considerations. Since the terms   XH connector   and   VH connector   are often used interchangeably in informal discussions, we explain the actual technical distinctions and selection criteria. By understanding these factors, teams can reduce risk, improve sourcing efficiency, and ensure better alignment between engineering and supply chain priorities. Overview of XH connector and VH connector In electronic devices, wire-to-board connectors differ mainly by pitch, current capacity, and retention features. The  XH connector  is optimized for compact designs with limited space, while the  VH connector  targ...
