Modular Jacks with Magnetics

GCT’s Magnetic Modular Jacks integrate RJ45 connectivity and Ethernet magnetics into a single, compact solution—reducing PCB footprint, simplifying layout, and lowering overall BOM complexity. By eliminating the need for external transformer components, these connectors help engineers streamline designs while maintaining consistent Ethernet performance.

Designed for industrial, networking, embedded, and computing applications, the range supports 10/100/1000 Base-T to 2.5G speeds and is available in single or dual-port configurations, including combined RJ45 + USB-A (3.0) options. Multiple orientations, latch styles, and height profiles provide flexibility for dense layouts and enclosure constraints, while shielded housings and optional LEDs support reliable operation in electrically noisy environments.

Key Features

1. Integrated Ethernet Magnetics
Factory-matched magnetics support 10/100/1000 Base-T to 2.5G speeds, maintaining signal integrity while reducing PCB footprint and external components.

2. Flexible Port and Interface Options
Available in single or dual-port formats, including RJ45-only and RJ45 + USB-A (3.0) combinations, to support a wide range of system architectures.

3. Mechanical and Layout Versatility
Right-angle and vertical PCB mount options, tab-up or tab-down latch styles, and low height profiles from 11.31 mm accommodate varied enclosure and board designs.

4. Shielded, Standards-Compliant Construction
Metal housings with EMI grounding fingers. Designs conform to IEC60603, FCC PART68 and fully RoHS and REACH compliant for production readiness.
