As device designs continue to get smaller, thinner, and more complex, hardware engineers face increasing pressure to optimize internal layouts without compromising performance. One essential component that enables this level of design flexibility is the Vertical RJ45 Jack—a compact, top-entry Ethernet port ideal for space-sensitive applications.
At LINK-PP, we specialize in manufacturing high-performance magnetic RJ45 connectors, including a full line of vertical-mount RJ45 jacks that combine signal integrity, EMI shielding, and compact footprint.

What Is a Vertical RJ45 Connector?
A Vertical RJ45 Connector, also known as a top-entry RJ45 jack, is mounted perpendicular to the PCB. Unlike right-angle (side-entry) jacks, the cable plugs in from the top, allowing for vertical cable management and more efficient board layout.
These connectors follow standard Ethernet protocols (10/100/1000Base-T) and are available with or without integrated magnetics and LED indicators.
Key Advantages
PCB Space Optimization
Vertical orientation frees up horizontal board space, making them ideal for dense or stacked designs.EMI & Signal Integrity
Many models feature integrated magnetics and full shielding to reduce electromagnetic interference.Strong Mechanical Retention
Most vertical RJ45 jacks use through-hole technology (THT), which ensures a secure connection even in high-vibration environments.Optional LED Indicators
Integrated green/yellow LEDs allow quick diagnostics for link/activity status.
