The 6116151-1 is a stacked modular jack assembly featuring a 2 x 1 port configuration with 8 positions and 8 contacts per port, delivering Category 5 performance suitable for high-speed data transmission. This shielded jack is designed without LEDs and provides PCB-only grounding, with insert-molded contacts ensuring positive connection throughout the equipment's operational life. The device meets or exceeds FCC Part 68 regulations and EIA/TIA 568A standards, achieving Near End Crosstalk (NEXT) performance exceeding -40 dB on all pair combinations at 100 MHz. Electrical specifications include a 1.5 A maximum current rating at 25 °C, 150 VAC maximum voltage rating, 1000 VAC dielectric withstanding voltage, and 500 MO minimum insulation resistance, with shielding effectiveness of 20 dB minimum across 10 to 200 MHz. The jack operates from -40 °C to 70 °C, supports 750 mating cycles, and features low profile and narrow width design to maximize port density in compact installations. Common applications include network switching equipment, telecommunications infrastructure, and data center interconnects where reliable Category 5 performance and space efficiency are critical.
