HMI

Industrial HMI (Human-Machine Interface) modules serve as the critical interface between operators and automated systems, including touchscreens, keypads and display panels that relay real-time status and control commands. In harsh factory environments with frequent operator contact, load switching and electromagnetic noise from motors and drives, HMIs are susceptible to electrostatic discharge (ESD), transient overvoltages and conducted electromagnetic interference (EMI). YINT Electronics’ protection solution integrates ultra-low capacitance ESD protection arrays to safeguard sensitive signal lines, high-power TVS transient suppressors to clamp voltage spikes, and EMI filtering components such as common-mode chokes and ferrite beads to reduce conducted noise, ensuring stable operation and clear display interfaces in industrial automation systems.
