Smart factories are raising the bar for machine design

As factories adopt more automated, intelligent machines, manufacturers expect equipment that supports higher availability and protects uptime. Machine builders can meet those expectations by treating switching, motor starting, control power, and safety as deliberate design decisions rather than commodity component selections.
