Right-Angle Unshielded RJ45 Jack for Through-Hole Assembly
The TE Connectivity 5557804-1 is an 8p8c RJ45 jack — a standard Ethernet receptacle for Cat3-rated twisted-pair cabling. It carries 8 contacts in a single row, arranged per the T568A/B pinout common to 10BASE-T and 100BASE-TX installations.
Unshielded — No EMI/RFI Protection
This jack is unshielded (no metal shell or grounding tabs), so it does not provide electromagnetic or radio-frequency interference containment. It is suited for environments where conducted or radiated noise is not a concern — office LAN drops, internal equipment wiring, or control networks inside a grounded metal cabinet. For industrial floors, motor drives, or wireless base stations, a shielded RJ45 jack (with a metal shroud and drain wire connection) would be the correct choice.
Gold Contacts for Repeated Mating Cycles
The phosphor bronze spring temper maintains normal force on the RJ45 plug's tines over the connector's lifetime.
Board Guide and Keying for Alignment
The housing includes a board guide and keying features. The board guide aligns the jack to the PCB during through-hole insertion, which prevents bent pins when the part is loaded into a wave-solder fixture. The keying ensures the RJ45 plug mates in the correct orientation — the tab on the plug latch engages the housing slot, so it cannot be inserted upside down.
