Gigabit Ethernet Jack with Board Lock and EMI Shielding
The TE Connectivity 6-2301994-1 is a single-port RJ45 jack rated for 10/100/1000 Base-T and AutoMDIX, meaning it handles standard Fast Ethernet and Gigabit Ethernet traffic with automatic crossover detection. The shielded body with EMI fingers keeps radiated noise inside the enclosure, which matters when the jack sits near a switching supply or a wireless radio.
Board Lock and Through-Hole Retention
This is the difference between a jack that stays put after a few hundred plug cycles and one that lifts its pads. The through-hole mounting gives a stronger mechanical bond than an SMT version would, especially important when the cable is routed through a panel and the connector takes side loads. Height above board is 0.445" (11.30mm) — check your enclosure lid clearance before layout.
Status LEDs and Construction
The jack carries green and orange-yellow LEDs for link and activity indication. The shield is brass, and the contacts are copper alloy with gold flash. Eight cores per jack is standard for RJ45.
