Industry Applications

Proven Performance Across Industries

Industrial PCs (IPC)

Ideal for compact fanless embedded systems where front-panel IO space is extremely limited.

Single Board Computers

Popular on SBCs (like Raspberry Pi alternatives) to maximize feature density on small PCBs.

Set-Top Boxes (STB)

Combines Ethernet for streaming and USB for media playback/updates in a single rear-panel connector.

Laptops & Notebooks

Consolidates network and peripheral connections (scanners, printers) for retail terminals.

Network Switches

The primary use case. 2x4 and 2x6 stacked jacks allow for 24-port and 48-port switch configurations in 1U racks.

Medical Carts

Ruggedized combo jacks provide reliable data and peripheral connections for mobile medical workstations.

Why Choose Our RJ45 Combo Connectors?

Taiwan-Made Precision Engineering

Unlike generic commodity connectors, our jacks are engineered in Taiwan with high-precision stamping and molding to ensure consistent mechanical stability.

Comprehensive Type-A to Type-C Support

We don't just offer legacy Type-A. Our product line includes modern USB Type-C combo jacks, enabling reversible connectivity and future-proofing your designs for new peripherals.

Ultimate Space Efficiency

By stacking the Ethernet port above the USB port, you reduce the connector footprint on the PCB edge by nearly 50%, freeing up room for other components or allowing for smaller device enclosures.

Advanced Signal Isolation

Our combo jacks are engineered with strict internal shielding partitions that isolate sensitive LAN signals from high-speed USB 3.0/3.1 data lines, ensuring error-free transmission for both interfaces.

Why Choose Our RJ45 Combo Connectors?

Technical FAQs

Common questions from procurement and engineering teams.

What is a Modular Jack with USB Combo Connector?

A Modular Jack with USB Combo is a hybrid connector that stacks a standard RJ45 Ethernet port on top of one or more USB ports (Type-A or Type-C) in a single housing. This 'stacked' architecture saves approximately 50% of the PCB edge space compared to placing the connectors side-by-side.

Do you offer RJ45 combos with USB Type-C?

Yes. We manufacture stacked combo jacks featuring the modern USB Type-C interface below the RJ45 port. These support high-speed data transfer and reversible mating, perfect for next-generation industrial controllers and laptops.

Does the USB signal interfere with the Ethernet signal?

No. Our combo connectors use advanced internal metal shielding partitions to electrically isolate the high-frequency USB data lines (especially USB 3.0/3.1) from the Ethernet magnetic signals. This minimizes crosstalk and ensures EMI compliance.

Are Integrated Magnetics available for the RJ45 section?

Yes. The RJ45 portion can be configured as a 'MagJack' with built-in 10/100 or Gigabit transformers, further reducing the component count on your motherboard. Discrete (passive) versions are also available.

What USB speeds are supported?

We support the full range of USB standards: USB 2.0 (480 Mbps), USB 3.0 / 3.1 Gen 1 (5 Gbps), and USB Type-C configurations. We verify impedance matching to ensure reliable high-speed data transmission.
