It sits in the 5406275 base series as a 4-port, single-row, right-angle through-hole part — the kind you see on a network switch or industrial controller card where four jacks line up along the board edge. The Cat5 rating means it handles 100 MHz signals, good for 100BASE-TX and similar office-automation or light-industrial Ethernet links.
Shielding and EMI — Why the Finger Matters
This jack is shielded and carries an EMI finger — a spring contact that grounds the shell to the panel or chassis cutout. The board guide (a molded alignment post) helps the jack self-center during insertion into the panel cutout, so the finger lands where it should. No LED on this variant — the two indicator positions are populated with blank plastic.
Right-angle orientation, through-hole solder termination. The tab faces down — the latch on the mating RJ45 plug clicks toward the PCB.
That span covers unheated equipment rooms, outdoor enclosures with passive cooling, and industrial cabinets near machinery. The PA housing holds up to wave-solder temperatures; the gold contacts don't oxidize in humid storage.
Active lifecycle — no end-of-life notice.
