1. Innovative Design — Half-Thread Right-Angle for Enhanced Application Flexibility

The Kinghelm KH-SMA-K513-G48 features a half-thread right-angle design, offering greater flexibility and spatial adaptability compared to traditional straight SMA connectors. This shape facilitates PCB layout by reducing space occupancy and effectively avoiding interference with nearby components, improving installation convenience and safety. It is especially suitable for dense board-end connection applications.

Additionally, the female pin is manufactured with high precision, ensuring stable signal transmission with low loss. Precise pin dimension control guarantees perfect mating with the male pin, enhancing both mechanical and electrical connection performance.

2. Outstanding Corrosion Resistance — 48-Hour Salt Spray Test Ensures Durability

Kinghelm invests heavily in materials selection and surface treatment R&D. The KH-SMA-K513-G48 passes a rigorous 48-hour salt spray test, meeting industry-leading corrosion resistance standards. Whether in marine environments, humid and salty industrial sites, or extreme weather conditions, it guarantees long-term stable operation, minimizing signal degradation and contact failure caused by environmental factors.

This durability is especially critical for outdoor wireless equipment, communication base stations, and various high-end industrial devices, significantly improving reliability and reducing maintenance costs.

3. Premium Materials and Manufacturing Process for Exceptional Performance

The KH-SMA-K513-G48 SMA connector uses high-strength brass and high-purity gold plating, ensuring excellent mechanical strength and superior electrical conductivity. The gold plating reduces contact resistance and prevents oxidation, securing stable and high-quality signal transmission.

Its precision right-angle plug-in design withstands insertion forces effectively, maintaining a firm interface and preventing loosening or poor contact caused by vibration or repeated mating cycles. Weighing approximately 3.4846 grams, it balances robustness with lightweight construction to meet modern electronic device design requirements.
