Selection Notes

The HMISTM6400 is the modular version of the 7-inch ST6 panel, mounted through a single Ø22 mm pushbutton-style hole instead of a 4-screw panel cut-out, and it adds 2 Ethernet ports rather than the single Ethernet port on some ST6 siblings. It is the only panel in this ST6 selection carrying marine approvals (DNV, ABS, RINA, BV) and a cULus Class I Div 2 hazardous-location rating, so specify it for shipboard HMI or explosive-atmosphere panel builds rather than the standard HMIST6400.
