8p8c RJ45 Jack for Cat5 Ethernet Links
It sits in the 406507 series of right-angle, through-hole Ethernet connectors. The jack carries green and yellow LEDs on the port face for link and activity indication — a standard feature on managed switch and industrial Ethernet port designs. The thermoplastic housing is RoHS3 compliant.
Shielding and EMI Management
This jack is shielded and includes an EMI finger — a spring contact that grounds the shell to the panel or chassis ground plane. The EMI finger provides a low-impedance path for shield currents before they reach the signal contacts, which matters for radiated emissions compliance in industrial controllers, PoE injectors, and telecom aggregation gear. The tab direction is up, matching the standard RJ45 plug latch orientation.
Cat5 Rating and Signal Path Limits
The Cat5 rating means this jack is specified for 100 MHz bandwidth — sufficient for 1000BASE-T (Gigabit Ethernet) over four twisted pairs. It is not rated for Cat6 (250 MHz) or Cat6a (500 MHz) performance. If the application calls for 10GBASE-T or higher-frequency signal integrity, a Cat6a-rated jack from the same series would be needed. The single-row, single-port layout keeps crosstalk between adjacent ports out of the picture.
Procurement and Lifecycle
The part ships in tray packaging.
