The TE Connectivity 1-2301994-1 is a single-port RJ45 jack designed for PCB mounting in networking equipment, industrial controllers, and any device requiring a shielded Ethernet interface. It carries 8 cores per jack, matching the standard 8P8C (RJ45) pinout for 10/100/1000BASE-T applications. Through-hole solder termination provides a robust mechanical anchor compared to SMT variants, especially in environments with repeated cable insertion and removal.
This jack is fully shielded with an EMI finger (Shielded, EMI Finger) on a brass shield body. For an engineer laying out a noisy industrial backplane or a PoE switch, the shield continuity reduces radiated emissions and improves immunity without adding a separate ferrite.
Board Retention and Assembly Features
Two features simplify assembly and improve reliability in the field. The board guide (Board Guide) aligns the jack during placement, preventing tombstoning or skew on the pick-and-place line. These are standard on TE's 2301994 base series and make the part a drop-in replacement for existing designs that already use board-lock RJ45 jacks.
