Its three ports in a single row save board space in Ethernet switch, router, and industrial control panel applications where multiple network connections are needed at a board edge. The EMI finger on the shield provides a low-impedance ground path to the panel or chassis, which helps contain radiated emissions in equipment that must pass FCC or EN 55032 limits.
Shielding and Contact Plating
The shield is built in, with an EMI finger that contacts the panel cutout — no separate ground clip needed. Tin-plated contacts at this thickness would wear after a few dozen cycles; the gold here keeps contact resistance stable over hundreds of insertions.
Mounting and Assembly
The tab faces down, so the locking latch on the mating plug engages from the bottom — check your panel cutout orientation against this.
