An Es-Key multiplexed network can be made up of numerous types of modules (nodes) and sensors each with their own specific functions communicating via SAE J1939 protocol. Multiplexing is a method that enables the electronic components of a vehicle to communicate, or “talk” to each other in a more efficient manner than ever before. Rather than using a multitude of copper wires between each switch, relay, and component, individual solid-state modules, or “nodes” use microprocessors to communicate between each other to activate the selected circuit.

Class 1 offer a range of pre-configured electronic components that can be used in stand-alone application or integrated into an Es-Key system.
In keeping with the same rugged design philosophy as the Es-Key range, these components can be utilised in a variety of fixed plant and mobile applications.
