It is specified for Cat3-rated applications, meaning it supports voice and 10BASE-T Ethernet signaling over the full 8-position, 8-contact layout. This is an unshielded jack (no metal shell or EMI gasket), so it relies on the cable-side shield termination or the system-level chassis ground for noise control — typical for office LAN drops, low-noise industrial control networks, and consumer equipment where the cable plant handles the shield path.
Board Fit and Mechanical Retention
Three mechanical features lock this jack into the board and the panel. Board lock — the through-hole solder posts anchor the connector against the shear force of repeated plug insertions and cable strain. Keyed — the housing has a polarising key that prevents inserting a non-keyed RJ45 plug or an upside-down plug; this is a common requirement on equipment where a mis-mated plug could short adjacent pins on the PCB. Panel stops — the flange face sets the z-height against the enclosure cutout so the jack sits flush with the panel face. The tab direction is down, meaning the latch release for the mated plug is on the underside of the jack. Termination is solder — through-hole only, not press-fit. The single-row, single-port layout keeps the footprint compact for dense port arrays.
