12″ Compact Panel PC
for CNC Machine Control
Fanless · IP65 · LEGO MODE™ Modular I/O · 10th/12th Gen Intel® Core™ i3/i5/i7 · Space-Efficient OEM Design
Right-Sized for Compact CNC Enclosures
At 299×237.5×74.6mm, the EPC-S12X2A fits control cabinet panels where a 15″ unit would require costly enclosure redesign. It’s the preferred choice for entry- and mid-range CNC machine builds — laser engravers, woodworking routers, and small-format plasma cutters — where panel real estate is limited but computing performance cannot be compromised.

Application
Why CNC Machine Builders Choose the EPC-S12X2A
Compact Form Factor — Fits Tight Panels
299mm wide body fits standard 300mm-wide electrical panel doors. No enclosure modification needed for most CNC cabinet designs, reducing OEM integration time and tooling cost.
IP65 Front Seal — Shop Floor Ready
Metal dust, coolant mist, and cutting debris are present in every CNC environment. The IP65-rated front panel keeps contaminants out while maintaining full touch responsiveness through gloved-hand operation.
3×COM for Motion Control Integration
Three serial COM ports cover the most common CNC configurations: one for the motion control card, one for the spindle drive, one for auxiliary I/O or barcode scanner — all without USB adapters.
Fanless — Zero Maintenance Cooling
No fans, no filters, no scheduled cleaning. Passive thermal design keeps the unit running 24/7 in dusty cutting environments without the fan-failure risk that plagues standard industrial PCs.
9~36V Wide Voltage Input
Directly compatible with 12V and 24V DC power rails standard in CNC electrical cabinets. Eliminates the DC-DC converter stage, simplifying BOM and reducing points of failure in the power chain.
Same Platform as 15″ — One Vendor, Two Sizes
EPC-S12X2A and EPC-S15X2A share the same LEGO MODE™ architecture, OS image, and driver stack. OEMs maintaining both compact and standard machines manage one software platform, not two.
