Shielded Right-Angle RJ45 with Board Lock
It carries a Cat3 rating, which means it's specced for signal frequencies up to 16 MHz — fine for 10BASE-T and 100BASE-T4 Ethernet, but not for the 100 MHz needed by Cat5e or the 250 MHz of Cat6. The board lock and keyed features, along with panel stops, help locate the connector accurately on the PCB and keep it anchored during the solder wave and through vibration in service.
This is a right-angle through-hole solder termination — the pins come out the bottom of the body and sit perpendicular to the PCB edge. The tab faces down, which is the common orientation for a standard RJ45 jack on a vertical PCB edge. The single-row, single-port layout keeps the footprint compact. No separate ground wire is needed.
