High-performance integrated magnetic jacks for 100/1000/2.5G/10G Base-T applications.
Optimizing PCB Space and Signal Integrity in the Era of 5G and Industry 4.0
In the evolving landscape of data centers and industrial telecommunications, PCB real estate is at a premium. Stacked port RJ45 connectors allow for doubling the port density within the same horizontal footprint. By utilizing the vertical axis (2x1, 2x4, up to 2x8 configurations), engineers can design more compact switches and routers without sacrificing connectivity.
Modern RJ45 female connectors are no longer just passive components. They integrate magnetics—transformers and common mode chokes—to filter noise, provide electrical isolation, and manage signal integrity. Our stacked connectors are engineered with advanced EMI fingers and shielding to meet the stringent demands of 10G Base-T and PoE++ (Power over Ethernet) standards.
From factory floor automation to outdoor telecom base stations, RJ45 connectors must withstand mechanical stress and environmental factors. Our connectors feature 50μ" gold plating on contacts and robust thermoplastic housings, ensuring 750+ mating cycles and reliable performance in temperatures ranging from -40°C to +85°C.

Where high-density RJ45 connectors drive innovation.
Supporting Top-of-Rack (ToR) and Leaf-Spine architectures. Our 10G stacked connectors ensure high-speed data throughput with minimal latency, critical for AI training clusters and high-frequency trading servers.
Integration into Programmable Logic Controllers (PLCs) and industrial gateways. The PoE capabilities allow for single-cable power and data delivery to sensors and cameras across the factory floor.
Enabling the rollout of 5G small cells and GPON/EPON equipment. The multi-port stacked design is essential for compact outdoor units where space is extremely limited but port count must remain high.
State-of-the-art machinery ensuring sub-micron precision for optical and electronic components.
Expert insights into RJ45 connector procurement and technical specifications.
Integrated magnetics save significant PCB space by housing the transformers and filters inside the RJ45 shell. This also improves EMI performance by shortening the signal paths between the connector and the magnetics, reducing noise pickup.
Yes, our high-speed series is designed to handle increased current loads for PoE, PoE+, and PoE++ applications, supporting up to 90W power delivery while maintaining signal integrity at 10G speeds.
Standard lead times range from 2 to 4 weeks depending on the complexity and volume. Our strategic supply chain of 850 partners ensures we maintain stable production even during peak demand cycles.
