The TE Connectivity 5555154-4 is a shielded modular jack with 6P6C contact arrangement, covering RJ11, RJ12, RJ14, and RJ25 wiring schemes. Board lock and panel stops provide mechanical retention against vibration and cable strain, making this jack a fit for industrial control panels, telecom equipment, or any enclosure where the connector sees field service.
Shielding and Environmental Rating
The shielded construction means the jack has a metal shell that bleeds EMI to the PCB ground plane — important for data lines in electrically noisy environments like factory floors or server rooms. The Cat3 rating indicates the jack is specified for voice and low-speed data (up to 16 MHz), not for Gigabit Ethernet — confirm the application bandwidth before committing.
This is a single-row, single-port jack with the tab facing down — the latch on the plug will click toward the PCB. Panel stops set the jack depth relative to the panel cutout, so the face sits flush. The connector ships in a tube, which is typical for hand-placement on a line — not tape-and-reel for automated pick-and-place.
