As wireless communication devices become increasingly miniaturized and modular, choosing the right RF connector grows ever more critical. A connector with a well-thought-out structure, stable performance, and ease of use can greatly enhance the entire system’s efficiency. Kinghelm’s KH-SMA-N-8496 is such a practical and reliable right-angle SMA female PCB connector, ideally suited for antenna connections, wireless modules, IoT devices, vehicle terminals, and other applications demanding compact size and signal stability.

Right-Angle Design Tailored for Compact Devices
The Kinghelm KH-SMA-N-8496 SMA female PCB connector features a standard 11-thread SMA female interface with a right-angle design that allows for a 90° cable exit when mounted on a PCB. This makes it especially suitable for space-constrained layouts. Compared to straight connectors, the right-angle form factor fits better in corner positions or densely packed multi-interface projects.

The overall design prioritizes practicality—not only saving space but also ensuring a secure and smooth connection. This makes it a great choice for engineers during early-stage structural layout and module integration.

Robust Construction, Stable Signal
The connector’s housing is made from copper alloy with a gold-plated surface, offering excellent oxidation resistance and electrical conductivity. The internal contact pin uses phosphor bronze, providing reliable conduction and high durability even under frequent plug-and-play conditions typical of development and testing environments. Weighing only 3.247 grams, this compact yet sturdy connector places no burden on the device structure, perfectly fitting tight spaces.

Typical Applications: Automotive, IoT, Wireless Modules
In vehicle positioning terminals, GPS and cellular modules often require external antennas, with SMA interfaces being a mainstream solution. The KH-SMA-N-8496 right-angle female connector enables antenna cables to extend naturally from the PCB edge to the device enclosure’s cable outlet, avoiding installation issues caused by excessive height.

In IoT wireless terminals such as LoRa, Zigbee, and Wi-Fi modules, using an SMA PCB connector to route antennas is key to improving signal quality. Thanks to its small size, firm solder joints, and stable connections, this product is ideal for low-power, cost-sensitive mass deployments.

Easy Installation, Suitable for Mass Production
As a PCB-mounted connector, the KH-SMA-N-8496 requires no through-hole chassis or extra locking nuts, significantly simplifying assembly. Its pin layout matches common PCB pad designs, making it compatible with automated pick-and-place and manual soldering processes.

Compared to traditional nut-fixed SMA connectors, it offers superior flexibility for board-mounted applications and large-scale manufacturing, especially within space-restricted enclosures.

Designed to Solve Common Engineering Challenges
Many engineers face frequent issues selecting RF connectors, such as:

1. Loose connectors affecting signal quality

2. Insufficient installation space

3. Structural interference complicating wiring

4. Excessive insertion loss or poor contact

Kinghelm’s KH-SMA-N-8496 SMA female PCB connector addresses these pain points through its right-angle structure, standardized interface, and solid build. It offers broad compatibility, secure connections, and reasonable cost—making it a highly trustworthy solution.
