CHECK BEFORE ORDERING
CONSIDER ANOTHER CODE IF
The GT2121E2 is a 12.1-inch 1280 × 800 resistive HMI panel in the Green Series 2 (GT2) generation of the Standard series. Only one code is published at this display size in the Green Series 2 (GT2) generation.
Published data: 12.1-inch display · 1280 × 800 · resistive touch · Quad-core ARM 1.5 GHz · 512 MB RAM · 4 GB flash.
The interface set is 2 Ethernet ports, 3 serial ports and 1 USB host port.
Panels in this size class are used on machine tools, packaging and filling lines, textile and printing machinery, battery and solar production equipment, rubber and plastics machines, and lifting equipment. The deciding factors are the panel opening, the protocol the machine program expects and the port set the cabinet already uses.
A 12.1-inch panel suits operators who work close to the machine. Where the panel is read from a distance or shows dense process graphics, compare the larger sizes in the same generation before ordering.
When a panel is replaced, the model code alone is not enough. Panels that share a display size and resolution still differ in interface options, memory, panel depth and certification, so the variant code has to match the cabinet.
Send the existing panel label, the panel opening measurements and photos of the cabinet wiring with the request. Every value published on this page comes from the reference specification table for the code.
Choose the GT2121E2 when the machine needs a 12.1-inch display at 1280 × 800 and the cabinet already uses 2 Ethernet ports, 3 serial ports and 1 USB host port.
Compare another model when the panel has to be larger, brighter, capacitive, or when the machine program expects an interface this group does not list. This group does not list Wi-Fi, 4G and CANopen.

COMPARE RELATED PANELS
Related model codes help you avoid choosing a neighbouring size by accident. A different series or generation is not a substitute without a cut-out and port check.

The reference table lists a 12.1-inch display at 1280 × 800 with 16.7 million colours and a resistive touch panel. Confirm the variant code if the machine already has a panel cut-out.
The published interface set is 2 Ethernet ports, 3 serial ports and 1 USB host port. Compare the cabinet wiring and the protocol the machine program expects before treating the panel as a replacement.
The panel is powered from DC 18 to 28 V. It fits a 299 × 219 mm panel opening. The panel body measures 309 × 229 × 43 mm. Confirm both against the machine before ordering.
Panel replacement is a compatibility question rather than a model question. Confirm the cut-out, the mounting depth, the port set and the protocol the machine program expects before ordering. CINKR checks these details against the model and photos you send.
