In today’s interconnected world of modern electronics, reliable and efficient connectors play a crucial “bridging” role. The KH-3.0AF90WJ-16.5 Type-A right-angle receptacle, launched by Kinghelm, is a meticulously engineered industrial-grade solution designed to meet demanding space and performance requirements. This compact yet powerful connector demonstrates exceptional adaptability and stability across a wide range of applications.

At its core, this connector is a standard USB 3.0 Type-A receptacle. USB 3.0—also known as USB 3.2 Gen 1—offers a theoretical data rate of up to 5Gbps, nearly ten times faster than USB 2.0. For data-intensive applications such as industrial camera image acquisition, real-time sensor data uploads, automated test equipment firmware updates, or high-speed external storage expansion, the KH-3.0AF90WJ-16.5 provides a solid physical foundation. Its 9-pin internal contact layout supports the USB 3.0 SuperSpeed differential pairs while maintaining backward compatibility with USB 2.0, ensuring data integrity and optimal speed.

The right-angle (90-degree) mount design is a key advantage of the KH-3.0AF90WJ-16.5. Unlike vertically mounted connectors, its pins bend at a right angle, allowing parallel mounting on the PCB (printed circuit board). This configuration is transformative in space-constrained environments such as industrial control enclosures, embedded system modules, portable diagnostic instruments, or robotic arm control units. By reducing the connector’s vertical height, the right-angle layout enables better component stacking, optimized thermal paths, and slimmer enclosure designs. It also simplifies internal cable routing, reduces bending stress, and enhances assembly convenience and long-term reliability.

As a receptacle, the KH-3.0AF90WJ-16.5 is fixed to the host or hub device and mates with a standard USB Type-A plug. Its structural design ensures firm, stable, and repeatable mating with the plug. Kinghelm incorporates high-quality gold plating in key contact areas of its industrial-grade connectors. Gold plating not only ensures excellent conductivity but also resists oxidation and corrosion, significantly reducing contact resistance over time and usage. This is vital for maintaining signal integrity (especially for high-speed USB 3.0 transmissions) and consistent power delivery, directly impacting long-term reliability and data integrity.

Another testament to its industrial-grade reliability is the wide operating temperature range of -30°C to +80°C. This enables the connector to function reliably under harsh environmental conditions—be it freezing temperatures in outdoor installations, heat exposure near industrial machinery, or elevated internal temperatures due to prolonged device operation. Its environmental resilience makes it ideal for industrial automation, outdoor communication equipment, in-vehicle electronics, energy monitoring, and special-purpose equipment, where stable operation is critical for safety, data accuracy, and system continuity.

In terms of physical specifications, the connector weighs just 2.65 grams and is supplied in tray packaging, reflecting a compact and lightweight design ideal for bulk production, automated surface mount processes (SMT reflow with pin wave soldering), or manual soldering. It’s optimized for efficient warehousing, transportation, and smooth integration into manufacturing lines.
