In today’s rapid development of wireless communication and smart hardware, RF connectors—though small—are crucial components in many devices. Whether in automotive systems, industrial automation, or IoT terminals, the stability of RF connections directly impacts data transmission continuity and device reliability. The Kinghelm KH-SMA-KWE17-GP SMA female connector with external thread, waterproof 17-thread 90° right-angle PCB mount is a practical SMA connector designed for these demanding application scenarios.

This connector uses a standard SMA interface supporting common frequency bands such as 2.4GHz and 5.8GHz, offering strong compatibility with various wireless modules. Its PCB mounting style combined with a 90° right-angle design makes it ideal for devices with limited space, such as automotive OBD terminals and embedded communication modules. Compared to typical straight connectors, this right-angle design saves space, optimizes cable routing, reduces interference, and improves overall wiring efficiency.
Notably, the KH-SMA-KWE17-GP SMA female connector features a 17-thread external waterproof structure. When connecting antennas, the threads tightly mesh, providing excellent protection. Even in outdoor environments with high humidity or dust, it prevents moisture ingress to keep internal circuits safe and stable. This design performs excellently in smart city, smart agriculture, and outdoor monitoring projects, making it a key focus for many device manufacturers.
Its advantages are particularly evident in the automotive industry. For example, OBD (On-Board Diagnostics) terminals are typically installed in concealed, harsh environments such as dashboards or undercarriages, where they must withstand continuous high temperatures, dust, moisture, and strong vibrations during vehicle operation. Traditional SMA connectors often face issues like signal instability or loose interfaces under these conditions. The KH-SMA-KWE17-GP SMA female connector , made from fully copper with gold plating, featuring a robust structure and PCB soldering support, demonstrates higher reliability in practical applications.
Its solder foot design is solid, allowing it to withstand frequent vibration and temperature changes on the PCB without loosening or de-soldering. After antenna connection, the metal threaded part forms a firm engagement that not only ensures waterproof protection but also maintains good signal integrity in high-frequency transmission. The all-copper material combined with gold-plated contact surfaces reduces signal loss and resists oxidation, guaranteeing stable output even in long-term automotive use.
As a result, many automotive communication device manufacturers prefer this type of waterproof, angle-optimized RF connector to enhance overall device stability and product lifespan. According to end-user feedback, stable connections mean less after-sales maintenance and improved positioning and communication continuity and accuracy—benefiting fleet management, remote monitoring, and related applications directly.
This connector is also widely used in IoT terminals, smart meters, and remote sensors. Many such devices are deployed outdoors in scattered locations with little maintenance, demanding even higher standards for RF connectors than typical industrial products. The KH-SMA-KWE17-GP’s waterproof, corrosion-resistant, and wide temperature tolerance design allows it to operate reliably over long periods, reducing overall device failure rates.
The product also balances bulk procurement and assembly convenience. Each unit weighs about 5 grams and is bagged for easy storage and management, making it suitable for automated production lines and large-scale OEM use.

In summary, the Kinghelm KH-SMA-KWE17-GP SMA female connector may be compact but features thoughtful design balancing protection, structure, performance, and assembly efficiency. Whether for automotive equipment, IoT communication, or outdoor industrial terminals, this connector provides stable, secure RF connections, making it a trustworthy component in many engineering projects.
