Omron NB Series and Samkoon EA/SK: economy-HMI selection guide
Compare Omron NB3Q/NB5Q/NB7W/NB10W with Samkoon EA/SK candidates by display, Ethernet suffix, serial ports, software and cut-out.
Short answer
What does this page recommend?
A technical alternative, not a drop-in substitute
Samkoon EA and SK models are technical candidates for the Omron NB Series economy machine-HMI use case based on display size and port layout. The NB-Designer project does not transfer directly; TW00/TW01 Ethernet differences, panel cut-out and the Omron device driver are revalidated for the exact model.

ProControl products to evaluate first
The exact configuration is selected after engineering review.
EA-070B V4
Basic 7-inch 800×480 serial-HMI candidate; it is not an automatic candidate for a network-dependent NB7W-TW01 project.
Open technical page
SK-102CS
10.2-inch 1024×600 candidate with Ethernet and two serial channels, close to an NB10W selection intent.

Similar requirement, different architecture
The table explains product architectures; it is not an exact order-code selection.
| Validation area | Omron NB Series (-V1) | Samkoon / ProControl candidate |
|---|---|---|
| Display and resolution | The Omron NB family includes NB3Q 3.5-inch/320×240, NB5Q 5.7-inch/320×240, NB7W 7-inch/800×480 and NB10W 10.1-inch/1024×600 classes. | EA-043A V4 provides 4.3-inch/480×272, EA-070B V4 7-inch/800×480 and SK-102CS 10.2-inch/1024×600; the legacy screen's pixel layout is redesigned. |
| Ethernet variant | In Omron's official NB table, TW01B-V1 variants include Ethernet/USB Host while TW00 variants do not have the same connection set. | Samkoon selection is not based on screen size alone; actual Ethernet status for EA models and SK-102CS is taken from the exact model page. |
| Serial ports and Omron protocol | The number and RS-232C/422A/485 role of NB serial ports vary by model; the Omron PLC connection uses a supported driver. | Samkoon serial electrical mode, pinout and Omron PLC driver are verified on the exact model/SKTOOL version; FINS support is not assumed. |
| Project environment | NB screens are built with NB-Designer; model objects, addressing and project-file structure belong to the Omron environment. | The SKTOOL project is rebuilt. Pages, images, fonts, addresses, alarms, recipes, trends and user permissions are not assumed to convert automatically. |
| Mechanical fit and lifecycle | NB3Q/5Q/7W/10W enclosures and cut-outs differ; product lifecycle and regional availability are checked from a current Omron source. | Samkoon cut-out, mounting depth, connector clearance, IP class, temperature and supply are verified from the exact drawing. |
| Migration acceptance | Ethernet/serial connections, PLC commands and operator functions in the NB project form the existing performance reference. | The new panel passes comparative FAT for all PLC data types, write locks, alarm history, recipes, restart and connection loss. |
Suitable scenario
When is it worth evaluating?
- Machines needing an economical local HMI and standard Omron PLC communications
- Modernisations where the NB-Designer project and panel cut-out can be rebuilt
- Projects where Ethernet needs can be reselected from a function list rather than a model suffix
Migration gate
Before making a decision
- Record the full NB model code, TW00/TW01 suffix, display and ports.
- Extract the Omron PLC driver, addresses, alarms, recipes and trends from the NB-Designer project.
- Verify Ethernet, serial-port, USB and PLC-driver scope for the Samkoon model.
- Compare cut-out, enclosure depth, IP, temperature, supply and product lifecycle.
- Approve PLC reads/writes, connection loss, restart and all operator functions during FAT.
Frequently asked
Clear answers about alternatives and migration
Is this a drop-in replacement?
No. It is not a direct substitute until exact model, electrical, protocol-role, mechanical, software and certification checks pass.
What should I provide for selection?
The exact existing code, diagram or I/O list, PLC/network data, supply, environment and special functions in use.
Is selecting any 7-inch Samkoon panel sufficient for an NB7W-TW01B-V1?
No. TW01 includes Ethernet and USB Host; alongside the display, the Samkoon candidate must be checked for networking, USB, serial ports, PLC driver and mechanical dimensions.
