8P8C Shielded RJ45 Jack for Cat5 Ethernet
The TE Connectivity 2-406541-3 is an 8-position 8-contact (8P8C) modular jack — the standard RJ45 footprint for Ethernet. It sits in the 406541 series as a right-angle, through-hole, shielded variant with an integrated EMI finger that grounds the shell to the panel face, keeping common-mode noise off the signal pairs. Rated Cat5, it handles 100 MHz signaling — enough for 100BASE-TX and 1000BASE-T runs in office LANs, industrial control panels, and telecom cabinets. The housing is a single-port, single-row design with a board guide that aligns the jack during wave-solder assembly. No LED indicators — this is a straight signal-pass jack for applications that handle link status elsewhere.
Shielding and EMI Finger — Why It Matters
The EMI finger on the shielded shell creates a low-impedance ground path from the jack body to the panel cutout.
