Explore our top-rated waterproof connectors and cable gland solutions — trusted by Czech industrial manufacturers, energy operators, and infrastructure engineers.
Czechia stands as one of Central Europe's most advanced industrial economies. The demand for high-quality cable glands and waterproof connectors continues to grow rapidly across its key sectors.
As Czechia accelerates its transition to smart manufacturing, renewable energy, and electromobility, the need for reliable, IP-rated cable entry and sealing systems has never been greater. From Škoda Auto's EV production lines in Mladá Boleslav to solar farms across Moravia and 5G rollouts in Prague, cable glands form the invisible backbone of every major infrastructure project.
Jnicon cable gland and waterproof connector solutions are deployed across a wide range of Czech industrial and commercial environments.
Czechia is home to Škoda Auto, Toyota Peugeot Citroën Automobile (TPCA), and Hyundai. Waterproof connectors and cable glands are essential for EV battery management systems, charging infrastructure, and automated production lines throughout Bohemia and Moravia.
South Moravia and the Ústí nad Labem region are expanding solar capacity rapidly. IP67/IP68-rated cable glands ensure durable, weatherproof connections in photovoltaic installations, wind turbines, and energy storage systems across Czech landscapes.
Prague's smart city initiatives and industrial park developments in Brno and Ostrava demand high-performance cable entry solutions for HVAC systems, intelligent lighting, security networks, and building automation platforms.
With Czech carriers deploying 5G infrastructure nationwide, outdoor-rated cable glands protect base station connections and fibre optic enclosures from the region's variable climate — from Prague's urban core to rural Vysočina.
Prague Metro expansions and Czech Railways (ČD) modernisation programmes require vibration-resistant, flame-retardant cable glands for signalling systems, traction power, and onboard electronics in rolling stock.
Czech machine tool manufacturers and automation integrators in Plzeň, Brno, and Ostrava rely on precision M12 and M19 circular connectors to link sensors, actuators, and PLCs in demanding factory environments.
The Czech cable glands and industrial connector market is evolving rapidly, driven by EU Green Deal targets, Industry 4.0 adoption, and the country's growing role as a Central European technology hub.
Czechia's National Energy and Climate Plan commits to significantly reducing coal dependency by 2033. This drives massive investment in wind, solar, and biomass infrastructure — all requiring IP-rated, corrosion-resistant cable management solutions that meet CE and ATEX standards mandated across the EU.
Czech manufacturers are rapidly integrating IoT sensors, collaborative robots, and AI-driven quality control. This creates surging demand for miniaturised, high-cycle-life circular connectors like the M12 series — capable of handling data, signal, and power in unified, space-saving form factors.
The Czech government's EV incentive programme and EU-funded charging network expansion are accelerating deployment of public and fleet charging stations. High-current waterproof connectors rated for DC fast charging are now a critical procurement category for Czech energy operators and municipalities.
Post-pandemic supply chain disruptions have prompted Czech OEMs and EPC contractors to diversify sourcing. Reliable Asian manufacturers with CE-certified products, fast lead times, and strong technical support — like Jnicon Group — are gaining significant market share as preferred alternative suppliers.
Jnicon Group is a high-tech enterprise specializing in advanced connection solutions. Our core product lines include industrial connectors, high-current connectors, controllers, 5G base station connectors, LED connectors, marine and yacht connectors, glass sintered connectors, and communication cables.

Innovation and intellectual property are central to our development strategy. To date, we have filed nearly 300 patents, with an average of over 80 new patent applications annually since 2019. Our annual R&D investment reaches approximately RMB 10 million, underscoring our position as a key national technology enterprise — delivering cutting-edge cable gland and connector solutions to markets including Czechia.
With our sealed air insulated system, there is no risk of gas leakage as the pressure inside and outside the cabinet remains the same — ensuring compliance with Czech and EU electrical safety regulations.
Throughout its lifecycle, there's no need for pressure monitoring or gas refilling, significantly reducing maintenance requirements — a key advantage for Czech industrial operators seeking low total cost of ownership.
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 — and strengthening its capacity to serve Czech and European customers with faster delivery and expanded product lines.
From technical certification to after-sales support, we are built to meet the expectations of demanding Czech and Central European industrial customers.
All Jnicon cable glands and waterproof connectors are manufactured to meet CE marking requirements and IEC/EN IP protection standards — essential for legal compliance in the Czech Republic and across the EU single market.
