Ethernet Modules

 Ethernet Modules
Industrial Ethernet Modules are rugged communication devices that enable industrial equipment—such as PLCs, drives, robots, sensors, and HMIs—to exchange data over Ethernet networks using specialized real time automation protocols like PROFINET, EtherNet/IP, Modbus TCP, and EtherCAT. Unlike standard Ethernet modules, they are designed for deterministic or time critical communication, operate reliably in harsh environments with high temperature, vibration, and electrical noise, support advanced network redundancy for continuous operation, and provide diagnostics and certifications tailored for industrial automation systems.

Mouser is an authorized distributor for many industrial Ethernet module manufacturers including Brainboxes, DIGI International, Innodisk, Intel, NetBurner, Phoenix Contact, Weidmuller & more. Please see our selection of Ethernet modules below.
