• Heat Dissipation: Pitch impacts heat dissipation. Smaller pitches can concentrate heat, particularly in high-power applications, leading to overheating. Select the right pitch to optimize heat management and prevent failures.
• Environmental Adaptability: Different environments have varying pitch requirements. Larger pitches in harsh conditions (e.g., high humidity or pollution) help reduce contamination and short-circuit risks, enhancing environmental adaptability.
• Cost Efficiency: Consider the cost-effectiveness of the pitch. Smaller pitches save space and increase integration but may incur higher manufacturing and maintenance costs. Balance space utilization with economic considerations to choose the most cost-effective pitch.

Selecting the ideal pitch for Pogo Pin connector involves evaluating mechanical, electrical, manufacturing, heat dissipation, environmental, and cost factors to ensure high performance and reliability.

6. Pitch and Other Connector Parameters, What Is Pitch?

In Pogo Pin connector design and selection, Pitch is crucial. This refers to how much room there is between pog pins that are close together, usually measured in millimeters. The right Pitch affects the connector’s performance and suitability and must be balanced with other key parameters:

• Contact Force and Pitch: A smaller Pitch means closer pins, which can reduce contact force. Weak contact force may affect connection stability. Therefore, in smaller Pitch designs, optimizing pin materials and spring design is essential to ensure sufficient contact force.
• Current Capacity and Pitch: The current capacity relates to pin cross-sectional area and Pitch. Smaller Pitch may limit pin size, affecting current capacity. For high-current applications, larger Pitch connectors are often needed to avoid overheating or damage.
• Durability and Pitch: Pitch size affects mechanical durability. Smaller Pitch increases mechanical stress between pins, reducing lifespan. For frequent insertions and removals, choose an appropriate Pitch to balance durability and size.
• Manufacturing Process and Pitch: Smaller Pitch requires higher manufacturing precision. As Pitch decreases, the difficulty and cost of production increase. Consider the feasibility and cost of production when selecting Pitch.

Choosing the right Pitch involves balancing contact force, current capacity, durability, and manufacturing process. Accurate calculations and testing can help find the optimal Pitch for your application, enhancing overall performance and reliability.
