When specifying an industrial computer, one of the first decisions is form factor. Embedded box PCs (compact, headless computers) and panel PCs (computers with integrated displays) each serve different application needs.
What Is an Embedded Box PC?
A compact, self-contained computer without a built-in display. Designed for headless operation, flexible display pairing, space-constrained installations, and distributed computing.
What Is a Panel PC?
A computer and display integrated into a single unit, typically with a touchscreen. A complete HMI solution designed for panel mounting with a sealed front bezel.
Comparison
| Criterion | Embedded Box PC | Panel PC |
|---|---|---|
| Display | External (optional) | Integrated |
| Typical Use | Headless / gateway / edge | Operator HMI / workstation |
| Size | Very compact | Larger (display-dependent) |
| Environmental | IP40-IP67 | IP65-IP67 (front) |
| Cost | Lower (no display) | Higher (display included) |
| Flexibility | Pair any display | Fixed display size |
| Component Replacement | Independent | Entire unit |
When to Choose a Box PC
- No human operator at the machine (headless/automated)
- Different installations need different screen sizes
- Maximum deployment density in control cabinets
- Independent component lifecycle — replace display or computer separately
When to Choose a Panel PC
- Operator workstations with regular human interaction
- Harsh environment HMI needing sealed front bezels (IP65+)
- Space-constrained panels where integrated design eliminates cables
- Regulatory compliance requiring pre-certified complete systems
Hybrid Approaches
Many facilities benefit from deploying both: panel PCs at operator stations and box PCs for distributed edge computing at individual machines.
Acnodes Corporation manufactures both embedded box PCs and panel PCs across a wide range of sizes and environmental ratings. Contact us to discuss which form factor best fits your application.
