Designing a reliable industrial control panel requires more than individual components — it requires the right technologies working. Whether you’re building new panels or upgrading existing systems, these essentials provide a solid foundation for power, protection, connectivity, and control together. From safe power distribution and protection to secure connectivity, noise suppression, and long‑term reliability, every element plays a critical role in system performance. Below highlights eight essential technologies from TE Connectivity that form the backbone of modern industrial control panels. These solutions help engineers simplify design, protect critical systems, maintain signal integrity, and ensure dependable operation in demanding industrial environments. Whether you’re building new panels or upgrading existing systems, these essentials provide a solid foundation for power, protection, connectivity, and control.
- Terminal Blocks – Power distribution and grounding within the control cabinet
- Internal Interconnects (Unsealed) – Compact, cost-effective connectivity for protected cabinet environments (wire-to-board / I/O connections)
- Relays – Isolation, switching, and protection between control and power
- Industrial Ethernet / Data Connectors – Reliable network connectivity for cabinet-level communication (industrial RJ45 for panel networking)
- Circular Connectors – Sealed panel interfaces for power and signal (M12 bulkhead; CPC for control panel and light I/O applications)
- EMI Filters – Power entry filtering to reduce electrical noise and protect control system performance (Schaffner)
- Passives / Switches – Operator control and critical protection (E-stop, toggles, reset)
- Sensors (Basic Position, Temperature, Proximity) – System feedback for monitoring and control
