6P6C Shielded Modular Jack — Right-Angle, Board Lock
It accepts RJ11, RJ12, RJ14, and RJ25 plugs — the 6p6c scheme covers single- and dual-pair telephone wiring plus some low-speed data links where the centre pair carries the signal and the outer contacts are unused or grounded. The shielded shell bleeds EMI before it couples into the signal path, so this jack belongs on a board that lives inside a metal enclosure or near a motor drive.
Shielding and Temperature Range
The metal shell is listed as shielded — that means the ground plane on the PCB ties through the shell tabs to the chassis or circuit ground, giving conducted and radiated noise a low-impedance drain before it reaches the 6p6c contacts.
