Combined Ethernet and USB I/O in One Panel Cutout
The TE Connectivity A-RJ45 1-1775855-1 is a right-angle modular jack that integrates an 8p8c (RJ45, Ethernet) port with a USB A connector in a single shielded housing. This dual-function design saves board space and simplifies panel cutouts in equipment that needs both wired network and USB device connectivity — common in industrial controllers, point-of-sale terminals, and network appliances. The 8p8c pinout follows the standard T568A/B wiring scheme for Ethernet, and the USB A contacts are positioned alongside for a combined I/O footprint. The connector is shielded, which reduces radiated EMI from the Ethernet and USB lines — important for passing FCC/CE emissions testing in metal-enclosed equipment. The housing is glass-filled PBT, a material that holds up to wave-solder temperatures and provides the dimensional stability needed for the combined jack geometry.
Board Locks and Through-Hole Mounting for Mechanical Retention
The through-hole mounting gives a stronger mechanical bond than an SMT-only jack, especially important for the USB A port which sees higher insertion forces than an RJ45 alone.
