Standard Modular Jacks

Molex Standard Modular Jacks ensure high performance and superior reliability across a wide range of Ethernet data speeds. These modular jacks deliver fleixibility for a variety of design needs and include RJ11 and RJ45 jacks in right-angle or vertical top/bottom-entry styles with through-hole or SMT soldering. The jacks come in single-port or ganged and stacked multi-port versions. Molex Standard Modular Jacks offer Cat 3, Cat 5, and Cat 5e speeds and a variety of options, including shielding for advanced EMI/RFI protection. Applications include a wide range of consumer, home appliance, medical, telecom/networking, and industrial uses.
