More About Molex
Molex focuses on the design and manufacture of electronic interconnect products deployed across enterprise, industrial, and automotive environments. Its portfolio spans board-to-board, wire-to-board, I/O, power, RF, and fiber-optic connectors (connectivity), as well as cable assemblies (connectivity) that link subsystems inside servers, networking equipment, industrial controllers, vehicles, and consumer devices. These components are used by OEMs and system integrators to implement electrical and data pathways in architectures that require predictable performance and adherence to global standards.
In data center and cloud infrastructure, Molex provides high-speed copper and fiber interconnects (data center networking connectivity) used between servers, storage, and network switches. These products are typically aligned with Ethernet and PCI Express (PCIe) ecosystems and are designed to support common serial interface standards. High-density backplane and mezzanine connectors (server and networking hardware connectivity) support compact equipment designs and higher port counts in switches and routers. For telecommunications service providers, Molex interconnects are used in wired and wireless network equipment, supporting transmission of power and high-bandwidth data in central offices, radio access networks, and edge platforms.
In automotive and transportation, Molex provides connector families and cable assemblies (automotive connectivity) for power distribution, in-vehicle networking, infotainment, sensors, and driver-assistance systems. These components are integrated into vehicle electronic and electrical architectures, including zonal and domain controller designs, and are used with protocols such as CAN, LIN, Ethernet, and other in-vehicle communication schemes where applicable. Ruggedized connectors and sealed products (harsh-environment connectivity) are used in applications that must withstand vibration, temperature extremes, and exposure to fluids.
Within industrial and factory automation, Molex supports PLCs, robotics, machine control, and industrial networking through connectors, I/O modules, and cordsets (industrial connectivity). Offerings are aligned with fieldbus and industrial Ethernet architectures adopted in manufacturing plants and process automation environments. These products are used to connect sensors, actuators, drives, and control systems, contributing to deterministic communication and power distribution on the factory floor.
Across these markets, Molex works with OEMs and enterprise equipment vendors to provide standard catalog components and custom-engineered interconnect solutions (custom connectivity services). This can include application-specific connectors, overmolded cable assemblies, and integration support tailored to mechanical, electrical, and environmental constraints. In an enterprise IT and Operational technology (OT) context, Molex is generally categorized under electronic components and connectivity, covering signal, power, and data interconnect hardware that underpins servers, storage, networking gear, industrial control systems, and vehicle electronics.
