Selection Notes
The round-pipe support-arm mount is expandable, so this extension unit is the pick when the arm run needs to grow after the initial install, unlike the fixed flange-top mount on the -0AX0 operator panel variant. Both share the same 12.1-inch display, IP65/NEMA rating, and PROFINET interface, so the mounting geometry is the only variable that decides between them. IP65 front and rear holds up in washdown-adjacent cells without the stainless housing of the hygienic MTP1200.
