M20 Pin Headers: Reliable Internal PCB Connectivity for Industrial Power & Control Equipment

Stable connections where reliability matters most

Air circuit breakers and motor protection relays rely on stable internal PCB connectivity to support reliable operation and long-term system performance. Component selection must support consistent electrical contact, withstand industrial operating conditions, and remain cost-effective for volume production.

This application highlights how Indess M20 pin headers (2.54 mm pitch) are used for internal PCB interconnections inside industrial power and control equipment, followed by an overview of the key features that support consistent and cost-effective PCB design.

Ideal for Internal PCB Applications

In air circuit breakers and motor protection relays, M20 pin headers are commonly used to create reliable board-to-board or board-to-wire connections inside enclosed systems. While not exposed to external environments, these components must still perform reliably under normal operating temperatures, vibration, and long service life expectations within enclosed systems.

Typical applications include:

• Air circuit breakers (ACB)
• Motor protection relays
• Industrial control units
• Power control and protection assemblies

By providing consistent contact and mechanical stability, M20 pin headers help ensure uninterrupted operation of critical industrial equipment.
