The TE Connectivity 5406299-1 is a shielded RJ45 modular jack with 8 positions and 8 contacts (8p8c), terminated through-hole at a right angle. It carries a Cat5 rating, meaning the signal path is characterized to 100 MHz — enough for 10/100/1000BASE-T Ethernet in industrial controllers, IP cameras, and building-automation panels.
Right-Angle, Through-Hole, Shielded — The Mechanical Fit
The 90° orientation and through-hole mounting are a deliberate choice for a cable connector that sees insertion and withdrawal forces. Through-hole solder joints anchor the shield tabs and the port body to the board better than SMT pads alone, especially when the cable is routed near a panel cutout. The board guide aligns the jack during wave-solder assembly, preventing tombstoning or shifted grounds. The tab direction is down — the latch that retains the RJ45 plug faces the bottom edge of the board. This matters when the jack is mounted on a vertical mezzanine card or near a board edge: the plug release is accessible from below, not from the top.
