Selecting the correct Berg Connector (commonly known as 2.54mm pitch pin headers or housing connectors) requires a focus on pitch precision, contact material, and current rating. For industrial use, prioritize Phosphor Bronze contacts over brass for better elasticity and conductivity. Ensure the insulator material is UL 94V-0 flame retardant (typically PBT or Nylon-6T) to meet safety standards. Additionally, verify the plating thickness, usually measured in Gold Flash or 3u" to 30u" Gold plating, to prevent oxidation in high-humidity environments.
