Shielded 8P8C Jack for Legacy Ethernet and Voice
The TE Connectivity 3-1734577-1 is a vertical through-hole modular jack with 8 positions and 8 contacts (8P8C), the standard RJ45 form factor for Ethernet and telecom interfaces. The shielded shell provides a low-impedance path to chassis ground, containing radiated emissions from the unshielded twisted-pair cable in industrial or office equipment enclosures. Rated Category 3, this jack is designed for 10BASE-T Ethernet and voice-grade applications up to 16 MHz. The Cat3 rating limits the bandwidth relative to modern Cat5e or Cat6 jacks — a critical fit check if the BOM specifies a higher performance category for 100BASE-TX or Gigabit Ethernet. The single-row, single-port vertical orientation suits board-edge or panel-mount layouts where the cable enters from above.
Board Lock and Solder Termination
Two board-lock features on the through-hole solder tails anchor the jack to the PCB, resisting shear forces from repeated cable insertion and extraction. The user-selectable tab direction lets the integrator orient the latch tab for top-entry or side-entry cable routing before soldering. The PA46 glass-filled housing withstands lead-free reflow profiles without deformation.
