Product details

The TE Connectivity 2178126-2 is a CLOUDSPLITTER-series modular jack, wired 8p8c (RJ45) with a right-angle orientation for board-edge mounting. It is a shielded jack with EMI fingers, rated Cat5e, making it a fit for Ethernet ports where conducted emissions need to be contained at the panel or NIC interface.

The tab faces down, which means the cable plug latches from the underside of the jack — a detail to check against your enclosure cutout and PCB keep-out zone. The single-port, single-row body keeps the footprint compact, but the EMI fingers add a few millimetres of width compared to an unshielded jack.

Frequently asked questions

Is 2178126-2 compatible with Cat6 cables?

The jack is rated Cat5e, not Cat6. While an 8p8c mechanical interface will accept a Cat6 plug, the signal integrity at frequencies above the Cat5e ceiling is not guaranteed. For a Cat6-rated jack, look at the CLOUDSPLITTER variants with a Cat6 or Cat6a rating.

What is the difference between 2178126-2 and other CLOUDSPLITTER connectors?

The 2178126-2 is a right-angle, shielded jack with EMI fingers, Cat5e rated, with gold 50.0µin contacts. Other CLOUDSPLITTER jacks may be unshielded, have different tab directions, or carry Cat3/Cat5e/Cat6 ratings. The specific combination of shielding, EMI fingers, and Cat5e rating on this order code is what distinguishes it.
