Unshielded construction keeps the part cost low but means it is not intended for environments where conducted or radiated EMI must be shunted to chassis ground. A board guide aids alignment during through-hole soldering, and the shorting feature on selected positions can be used for loopback or presence detection in the circuit design. The tab faces down when mounted, matching the standard RJ45 plug latch orientation.","metaTitle":"TE 5557788-1 RJ45 Jack, 8p8c, Cat3, Right-Angle, Unshielded","metaDescription":"TE 5557788-1 RJ45 jack, 8p8c Cat3, right-angle through-hole, unshielded, 50 µ\" gold contacts.
