FAQ

Are these headers suitable for high-vibration environments, such as automotive or industrial machinery?

Yes, the headers feature mechanical retention and spring-force pins that maintain stable connections under vibration. However, in extremely high-vibration environments, using additional locking mechanisms or reinforcement on the PCB may enhance connection reliability and prevent accidental disconnections.

How does pin plating affect performance, and which plating is recommended?

Plating materials, such as gold or tin, significantly impact electrical conductivity, contact resistance, and corrosion resistance. Gold plating offers superior long-term conductivity and is ideal for sensitive or low-current applications, while tin plating provides cost-effective corrosion protection for general-purpose use. The choice depends on the application environment and required durability.

Can multiple rows of pins be used in high-current applications?

Yes, using multiple pins in parallel can distribute current load efficiently, reducing the risk of overheating individual pins. Careful design of pin spacing and layout is crucial to maintain proper heat dissipation and ensure safe operation under high-current conditions.

How should I clean or maintain the pin headers to ensure long-term performance?

Clean headers using a soft, lint-free cloth and isopropyl alcohol to remove dust or debris. Avoid abrasive materials or harsh chemicals that can damage plating. Regular inspection for corrosion, bent pins, or loose connections is recommended in industrial or high-use environments to maintain optimal electrical performance.
