The 50.0µin (1.27µm) gold plating on the phosphor bronze contacts supports repeated mating cycles typical of field-service Ethernet ports, while the Cat3 rating limits the signal path to 10/100BASE-T applications — not rated for Cat5e or Cat6 gigabit data rates. ## Board Lock and Keyed Housing — Retention and Mis-Mate Protection The keyed housing ensures the plug cannot be inserted upside down, which saves a rework step on the assembly line. The user-selectable tab direction gives flexibility in cable exit orientation relative to the board edge. ## Cat3 Rating — Know the Data-Rate Limit The Cat3 rating on this jack means it is specified for voice and 10BASE-T / 100BASE-T4 Ethernet signaling — not for 1000BASE-T or higher. For legacy 10/100 equipment or industrial fieldbus networks running at those speeds, the Cat3 rating is adequate and the 50 µ\" gold contacts maintain signal integrity across the rated temperature range.","metaTitle":"TE Connectivity 5555799-1 Modular Jack, 8P8C RJ45, Vertical","metaDescription":"TE 5555799-1 Cat3 RJ45 jack, 8P8C, vertical through-hole, 50µ\" gold contacts, board lock, -40°C to 85°C.
