RJHSE538A is a shielded, single-port modular jack connector with integrated LEDs and tab-up mounting orientation designed for data communications and telecommunications applications. The connector features top and side ground tabs for enhanced EMI shielding, with dimensions of 0.650 inches (16.51 mm) width and 0.530 inches (13.46 mm) height, and includes two LED indicators for status monitoring. Contact tails measure 0.100 inches (2.54 mm) and LED tails measure 0.125 inches (3.18 mm), with a tin-dipped zone for reliable soldering. The device accommodates 12 mounting holes (0.035 inches ± 0.002 diameter based on 2 LEDs) and 2 larger positioning holes (0.128 inches ± 0.015 diameter), making it suitable for PCB integration in networking equipment, telecommunications infrastructure, and industrial data communication systems.
