Explore our top-tier waterproof circular connectors equipped with precision-machined contact pins, optimized for Spain's demanding industrial and maritime environments.
Spain's industrial sectors are undergoing a massive transition driven by digitalization, automation, and green energy initiatives. As a key hub for automotive manufacturing, wind and solar power generation, and high-speed rail networks in Southern Europe, the demand for precision-engineered connector pins and heavy-duty electrical components has reached unprecedented heights.
From the automotive factories in Catalonia and Galicia to the vast solar farms in Andalusia, reliable electrical contacts are essential. A connector pin is not just a piece of metal; it is the critical point of transmission for power, signals, and data. In harsh Spanish climates—characterized by saline maritime conditions along the coasts and extreme heat in the dry interior—IP67 and IP68 waterproof ratings are non-negotiable for system longevity.
In Spain's sunny regions like Extremadura, solar plants utilize our high-current connector pins inside heavy-duty inverters and solar tracking systems. They resist UV radiation and high temperatures while maintaining stable electrical conductivity.
Along the Mediterranean coast, from Barcelona to Malaga, our IP67/IP68 metal waterproof connectors are installed in marine navigation, lighting, and power systems, protecting contacts from salt-water corrosion.
Spain's extensive high-speed rail network depends on reliable connection solutions for onboard sensors, communication lines, and coupling systems, where vibration resistance is critical.

With this sealed air insulated system, there is no risk of gas leakage as the pressure inside and outside the cabinet remains the same.
Throughout its lifecycle, there’s no need for pressure monitoring or gas refilling, significantly reducing maintenance requirements.
Since the establishment of Shenzhen Jnicon Technology Co., Ltd. in late 2013, the Group has experienced rapid and consistent growth. Since 2018, annual revenue growth has exceeded 200%, making Jnicon one of the fastest-growing companies in the domestic connector industry. By 2023, the Group had nearly 500 employees, with annual revenue reaching approximately RMB 300 million and total output value exceeding RMB 400 million.
In late 2021, the Group's board of directors approved a strategic investment of RMB 400-500 million in Shaoyang, Hunan Province, to expand the industrial chain and establish a new headquarters economy. The project covers a self-owned construction area of around 30,000 square meters and is expected to generate annual output exceeding RMB 1 billion. Upon full completion, it will become the largest high-current connector manufacturing base in China, supporting the Group's goal of listing on the ChiNext Board by 2029.
