Product Features
Wide Size Selection & Reliable Hardware
The SK Series covers all standard industrial display requirements with screen sizes ranging from 3.5″ to 15.6″. Powered by a fast dual-core ARM Cortex-A7 processor, it ensures smooth page switching, fast response times, and clear data display even under continuous heavy workloads.
Broad PLC Compatibility & Multi-Port Interfaces
Equipped with built-in RS232, RS485, and RS422 serial ports (and Ethernet on select models), the SK Series connects directly to your existing hardware grid. It comes pre-loaded with communication drivers for over 300 major PLC brands—including Siemens, Mitsubishi, Omron, Rockwell, and Delta—supporting standard Modbus RTU/TCP without extra adapters.
Unified Software Platform: SKTOOL
All configuration models are programmed via the license-free SKTOOL software platform. Built as a visual, drag-and-drop design environment, the software enables engineers to compile operational screens, real-time trend charts, and deterministic alarm logs without manual code editing. The SKTOOL system interface natively operates across 4 core localized languages: English, Russian, Turkish, and Chinese. For global machine deployment, the underlying software architecture features a multi-language compilation engine supporting the concurrent storage and runtime rendering of up to 50 distinct global languages for all project texts, diagnostic parameters, and operational screens.
Tough IP65 Sealing & Electrical Surge Isolation
Designed for harsh factory environments, the front screen features an IP65 waterproof and dust-proof rating to block moisture and industrial oil mist. To protect your data links, the serial communication circuits are equipped with built-in electrical isolation to completely prevent high-voltage surge disruptions.

Technical FAQ
Q1: What is the Samkoon SK Series HMI, and where should I use it?
A: The SK Series is our economic standard touch screen lineup, offering sizes from 3.5″ to 15.6″. Developed by our team of 200+ R&D engineers, it is a highly stable option for standard automation setups. It is widely used for factory control panels in packaging machines, CNC machine tools, textile equipment, conveyor lines, and food processing systems.
Q2: What makes the SK Series a better choice compared to other brands?
A: It gives you industrial-grade reliability at a highly competitive price point. With a solid hardware base (128MB DDR3 + 256MB Flash) and a clear 16.7-million color screen, it matches the display quality of international brands while significantly reducing your overall cabinet cost. Its full export readiness—featuring native software support for English, Russian, Turkish, and Chinese—makes it perfect for global machine exports.
Q3: How do I choose between models like the SK-043QE and SK-070QT?
A: Your choice depends on your installation space, networking needs, and budget. For small or tight control panels, choose the 4.3-inch SK-043 models. For standard industrial setups, the 7.0-inch SK-070 models are our most popular and versatile choice. If you are managing complex machinery with large data displays, go with the 10.2″ to 15.6″ models. Always check the model suffix if your setup requires a built-in Ethernet port.
Q4: Will it connect to my existing PLC system?
A: Yes. The SK Series natively supports all mainstream PLC brands, including Siemens, Mitsubishi, Omron, Rockwell, and Delta. It uses standard Modbus RTU/TCP protocols over its built-in RS232/RS422/RS485 and Ethernet connections, so you do not have to worry about device-matching issues or buying extra communication converters.
Q5: Is the SKTOOL software difficult for beginners to learn?
A: Not at all. SKTOOL is completely free and built around an intuitive drag-and-drop interface. You can place buttons, draw trend charts, and set up alarm logs without any advanced programming skills. If your project demands more complex logic loops, the software also supports secure macro scripts to handle advanced tasks while keeping your intellectual property encrypted and safe.
