What Are Original Equipment Manufacturer Panels?
Original equipment manufacturer panels are electrical control panels built for integration into another company’s machine, system, or packaged equipment. Rather than being standalone products, these panels become part of the OEM’s complete solution and may control motors, pumps, sensors, conveyors, or other automated functions.
The right panel-building partner can improve consistency, simplify production, and support reliable delivery as order volume grows.
How Do Original Equipment Manufacturer Panels Work?
Original equipment manufacturer panels bring a machine’s electrical controls together inside a properly designed enclosure. Depending on the application, a panel may include:
Programmable logic controllers and input/output modules Motor starters, variable frequency drives, and relays Circuit protection and power distribution components Human-machine interfaces, switches, and indicator lights Terminal blocks and communication equipment
The design must account for performance requirements, available space, the operating environment, documentation standards, and applicable certifications.
Why Do OEMs Outsource Panel Manufacturing?
Building panels internally requires specialized labor, production space, component sourcing, testing procedures, and quality-control systems. Outsourcing original equipment manufacturer panels allows an OEM to focus on its core equipment while working with a dedicated panel shop.
A qualified panel partner can help an OEM:
Maintain consistent construction across repeat builds Scale production without expanding an internal panel department Review designs for manufacturability and cost efficiency Coordinate components, wiring, labeling, and documentation Test panels before final equipment assembly
Standardization is especially valuable when an OEM produces the same machine repeatedly. Consistent layouts, components, wire identification, and testing procedures can simplify installation, troubleshooting, training, and replacement.
What Should OEMs Look for in a Panel Builder?
The best partner for original equipment manufacturer panels should offer more than assembly. OEMs should evaluate engineering support, quality systems, certification capabilities, production capacity, testing processes, and responsiveness.
Important services include design review, repeatable manufacturing procedures, factory acceptance testing, private labeling, and volume production support. Palmer DCS provides these capabilities while working as an extension of the OEM’s team.
Certification experience also matters. Qualified panel shops in UL Solution's Industrial Control Panel Shop Program may apply UL Marks to compliant custom-built or mass-produced industrial control panels at their facilities. The program supports design flexibility while requiring trained staff and established quality-control measures.
Benefits of Standardized OEM Panel Production
A well-managed original equipment manufacturer panels program can provide several advantages:
- Improved consistency: Repeatable layouts and manufacturing methods help each machine use the same control solution.
- Simplified scaling: OEMs can increase panel quantities without rebuilding the production process for every order.
- Reduced production risk: Design review and factory acceptance testing can identify issues before equipment reaches the field.
- Stronger brand presentation: Private labeling allows the panel to reflect the OEM’s specifications and identity.
- Responsive support: An experienced partner can assist with changes, troubleshooting, and future production needs.

Frequently Asked Questions
Are OEM panels always produced in high volumes?
No. Original equipment manufacturer panels may begin as prototypes or low-volume builds and later move into repeat production as demand increases.
Can an Existing Panel Design Be Improved?
Yes. A panel-building partner can review component selection, layout, wiring, documentation, testing, and manufacturability to improve consistency or efficiency.
Can OEM Panels Carry the Manufacturer’s Branding?
Yes. Private labeling can keep the OEM’s name, specifications, and product identity at the center of the finished panel.
