Right-Angle Shielded RJ45 for Panel-Mount Ethernet
It is designed for through-hole solder termination to a PCB, with the tab oriented downward. The shield includes an integrated EMI finger for grounding the cable braid directly to the chassis or PCB ground plane, which is the typical approach for keeping common-mode noise off the signal pairs in industrial Ethernet runs. This combination makes the 5555141-1 suited for equipment where the Ethernet port is mounted at the board edge and protrudes through a metal or plastic panel, such as industrial controllers, switches, or gateways. The part is rated Cat3 per the manufacturer's classification, which aligns with standard Ethernet cabling performance for 10BASE-T and 100BASE-TX signalling.
Shielding and Mechanical Retention
The shielded construction with an EMI finger is the main differentiator from an unshielded RJ45 jack. In a typical installation, the cable's shielded jacket contacts the jack's shell, and the EMI finger provides a low-impedance path to the PCB ground — this prevents the cable from acting as an antenna that radiates or picks up interference. The tab-down configuration matches the majority of standard Ethernet patch cables, where the latch is on the underside of the plug.
