The Molex 0438600013 is a right-angle RJ45 jack from the Series 43860, designed for through-hole mounting on a PCB. It carries 8p8c (8 position, 8 contact) layout standard to Ethernet, with a Cat3 rating that defines its performance ceiling for 10BASE-T and voice applications. The shielded shell with an integrated EMI finger provides conducted noise rejection at the board edge — useful in industrial or telecom equipment where the jack sits near a panel cutout.
This jack mates with any standard 8p8c (RJ45) plug — no proprietary keying. The tab direction is up, which matters for panel-mount alignment: the plug latch faces the same side as the board-lock posts.
