Molex’s Cat 3 jacks are designed for equipment using standard Ethernet cable.  5 and 5e support hardware using fast Ethernet technology.  Some examples include network routers, patch panels, printers, gaming consoles, and medical monitors.  Sealed RJ45 jacks and plugs are ideal for use in industrial lighting and test equipment. 

Our cutting edge Cat 6A and Magnetic Jacks meet the latest high speed performance requirements for 1 and 10 gigabit data rates.  For applications specifying power over Ethernet, such as network switches and digital televisions, customers can select our PoE Magnetic jacks that support the transmission of both data and power.  New technology helps lower costs and achieves PCB space savings while simplifying the system design.  Now customers can control power to connect at Ethernet devices such as color screens, voiceover IP phones, and security cameras. 

All jacks are available in Right Angle to fit a variety of design needs.  With either SMT or Through Hole mounting in single, ganged, or stacked multi ports.  Optional LED’s and light pipes are used to indicate signal activities at each port.  Plus our vertical jacks feature lower profiles for application that are space constrained.  As an option bot right angle and vertical styles come with internal or external shielding for proven EMI protection.  Modular plugs attach to cables and feature latches for easy mating and unmating.   Plug booths are available for increased durability and resistance to harsh environments.
