HMI Parts

HMI touch panels, mainboards, display screens and protective overlays — in stock, tested, shipped worldwide.

Overview

HMI parts — touch panels, mainboards, display screens and overlays — are the wear parts of human-machine interfaces. Cracked glass, dead backlights and failing mainboards are the classic failures we replace every day.

We supply HMI parts for Siemens SIMATIC MP/TP/OP series, Pro-face, Weintek, Mitsubishi GOT and Delta DOP panels, in new and tested refurbished condition.
