Each port is rated Cat4, which limits the usable frequency to 20 MHz — fine for 10BASE-T and 100BASE-TX, but not for Gigabit Ethernet or PoE+ applications that need Cat5e or better. Board locks on each port anchor the jack through the solder wave, taking the insertion and withdrawal shear off the signal pins — a splice is a fault waiting to happen, and a jack that rocks loose from repeated cable swaps is exactly that kind of failure. ## Why the 50.0µin gold plating matters for field life The tab direction is listed as Down, which means the board-lock posts and the solder tails are on the same side of the body — the jack sits flush against the PCB and the locks engage the plated through-holes before reflow. Four ports ganged in a single body means one pick-and-place event instead of four, and one connector to route traces to instead of four discrete footprints.","metaTitle":"Molex 43223 0432238140 RJ45 Jack, 8p8c, 4-Port, Right-Angle","metaDescription":"Molex 0432238140 RJ45 jack, 8p8c (Cat4), 4-port right-angle through-hole, gold 50.0µin plating, board lock.
