The TE Connectivity 5569381-1 is a shielded RJ45 modular jack carrying 8P8C contact arrangement — the standard 8-position, 8-conductor layout used for Ethernet. Two ports share the same metal shell, which carries an EMI finger to ground the shield to the chassis before noise reaches the signal pins. Rated for Cat5 performance, the channel is specified for 100 MHz baseband — a match for 10/100BASE-T Ethernet in industrial controllers, IP cameras, and building-management gateways.
Cat5 — What the Rating Covers
The Cat5 rating means the jack is tested to support 100 MHz signal bandwidth — sufficient for 10BASE-T and 100BASE-TX Ethernet. For a Gigabit Ethernet (1000BASE-T) link that requires Cat5e at a minimum, this part is not a fit. The screened metal shell and EMI finger do help contain radiated emissions from the 100 MHz switching edges, which is why Cat5 jacks with this shielding are still specified in EMC-sensitive designs that never exceed Fast Ethernet data rates.
Shielding and Board Fit
The EMI finger on the shell is a spring contact that mates with the panel cutout or chassis ground — it bleeds common-mode noise from the cable shield before the signal reaches the transformer. The tab direction is listed as up and down, meaning the jack accepts both orientations of the standard RJ45 latch. The board guide (a plastic alignment post) helps locate the part during wave-solder assembly and takes shear load off the through-hole tails when the cable is plugged and unplugged.
