SK series
SK series HMI – Linux panels from 3.5 to 15.6 inches
Every diagonal from 3.5 to 15.6 inches on one Linux platform, with the cut-out, the interface set and the feature level chosen by the part number.
The SK series is the mainstream range, and its naming is systematic: three digits give the diagonal (035, 043, 050, 057, 070, 102, 121, 150, 156), the next letter the cut-out family, and the trailing letter the feature level — E without Ethernet, S with Ethernet, G with 4G, W with Wi-Fi, D with CAN bus, T with an external RS485 terminal, F waterproof, H high definition, I isolated. A final G marks an IoT panel.
All of it shares one platform — Linux on a Cortex-A7 at up to 1 GHz dual-core, 128 MB flash, 128 MB DDR3, USB download and a USB host port — with three exceptions worth knowing: the compact SK-035FE, SK-035UE and SK-043UE keep a Cortex-A8 at 600 MHz, the 15-inch SK-H150AS moves to a quad-core A17 at 1.5 GHz, and the V3 revisions of the 7- and 10.2-inch models carry a Cortex-A8.
A panel can drive a micro printer, mount a USB stick, scanner, mouse or keyboard, and mirror its screen to a PC or phone over VNC. Two details decide most orders: the cut-out must match the door, and the protocol list must include whatever controller is already on the machine.
Cut-out families, not one aperture
A, B, F, G, H, M, Q and X cut-outs are shared across sizes, so a 7-inch model can replace an older panel without re-punching the door.
16.77 million colours
LED backlight, 350–500 cd/m² depending on model, 1024×600 on current 7- and 10.2-inch units and 1920×1080 on the 15.6-inch flagship.
Serial, Ethernet, CAN, 4G, Wi-Fi
Two COM ports on most models, three on the 10.2- and 15.6-inch units, with RS422 available alongside RS485.
Project protection
Configuration-file encryption plus dynamic and static HMI protection, so a machine builder can ship a panel without exposing the project.

Cut-out is the aperture in the enclosure, W × H. Panels are supplied with mounting clips; the waterproof models use blind-hole clips instead.

Build an SK part number
Pick the diagonal, the cut-out family and the feature level. The code assembles from the documented naming rule — confirm the final part number on the quotation.
Selection notes
How to choose within the range
- Screen diagonal comes from the code: 035, 043, 050, 057, 070, 102, 121, 150 and 156 for 3.5 to 15.6 inches.
- Resolution is per model: 320×240 at 3.5 inches, 480×272 at 4.3, 800×480 on the classic 7-inch units, 1024×600 on current 7- and 10.2-inch models, 1920×1080 on SK-156QS-G and 1024×768 on SK-H150AS.
- Aspect ratio is 16:9 except at 3.5, 5.7, 12.1 and 15 inches, which are 4:3 — plan the drawing before choosing a size if the door already exists.
- The enclosure is ABS+PC. Panel-mount units are IP65 on the front face; the waterproof models are IP67 over the whole unit.
- Confirm the PLC protocol required and plan the cut-out; dimensions are W×H×D with the cut-out stated separately in the table.
