What Is a Panel PC?
A panel PC is an all-in-one industrial computer that integrates a display, touchscreen, and a full PC system into a single unit designed for mounting directly into machines, cabinets, control panels, or swing arms on the factory floor. The B&R Panel PC 2100 is one well-known example of this product category — an ultracompact panel-mount and swing-arm PC family used with B&R's Automation Panel 900/1000 and Automation Panel 5000 series. B&R describes the Panel PC 2100 as combining a powerful, full-featured PC system in a housing whose dimensions correspond to those of a Smart Display Link receiver, with variants based on Intel Bay Trail architecture and single-, dual- and quad-core processor options.
Key Characteristics of Panel-Mount Industrial PCs
Panel PCs differ from ordinary desktop computers in several important ways:
-
Mounting options — Panel-mount (installed into a cutout in a control cabinet door or enclosure) and swing-arm/arm-mount (mounted on a articulated arm for operator access) are the two dominant form factors.
-
Touch input — Single-touch resistive or capacitive touchscreens are typical, with multi-touch increasingly common. Glove-friendly resistive touch remains popular in dirty or wet environments.
-
Front-panel protection — Industrial panel PCs are usually rated IP65 or similar at the front face so they survive washdown, dust, and coolant splash.
-
Wide input power — 24 V DC industrial power input is standard, often with galvanic isolation and reverse-polarity protection.
-
Long-term availability — Panel PCs are specified into machines with 10+ year service lives, so vendors commit to long product lifecycles and spare-part availability.
-
Fieldbus and I/O — Ethernet, serial (RS-232/RS-485), USB, and sometimes CAN or PROFINET connectivity are built in for direct connection to PLCs and drives.
Panel PC vs. Box PC vs. All-in-One
| Feature | Panel PC | Box / Industrial PC | All-in-One PC |
|---|---|---|---|
| Display | Integrated touchscreen | None (external monitor) | Integrated screen, usually non-touch |
| Mounting | Panel cutout, swing arm, VESA | DIN rail, wall, VESA | Desk stand, VESA |
| Typical ingress protection | IP65 front | IP20–IP54 enclosure | Office-grade |
| Power input | 24 V DC | 12–24 V DC | AC adapter |
| Best for | Machine HMI + control | Control cabinet compute | Office, kiosk, reception |
Typical Applications
Panel PCs are used wherever an operator needs to see and touch a machine interface: CNC and metalworking machines, packaging and filling lines, plastics injection molding, textile machinery, printing presses, and process control in food and beverage or life sciences. They also appear in building automation, access control, and kiosk-style installations where a rugged, always-on computer with a built-in screen is simpler to deploy than a separate box PC and monitor.
Choosing a Replacement or Alternative
When specifying a panel PC — whether as a new design or as an alternative to an existing panel-mount unit — focus on: screen size and resolution, touch technology, mounting style, processor performance class, RAM and storage, operating system (Windows 11 Pro, Windows 11 IoT, Linux, or no OS), and the exact I/O mix your machine needs. Matching the mounting dimensions and connector layout of the unit you are replacing minimizes mechanical rework.
Thinvent Products for Panel and Machine-Mount Applications
Thinvent builds industrial computers, mini PCs, thin clients, and all-in-one PCs engineered for continuous operation in demanding environments. Our Industrial PC line, including the IPC3 series with Intel® Core™ i3-1215U processors, 16 GB DDR4 RAM, and 1 TB SSD, delivers the compute, serial connectivity (including quad DB9 serial variants), and OS flexibility (Windows 11 Pro, Windows 11 IoT Value, DOS, or Thinux™ Embedded Linux) that machine builders need. For installations that require an integrated display, Thinvent's all-in-one PCs in 21.5" and 23.8" screen sizes provide a clean, single-unit operator interface. If you are evaluating an alternative to a panel-mount industrial PC, our team can help you match form factor, I/O, and operating system to your application.
