When sourcing Pogo Pins, you must prioritize Current Rating (Amperage) and Contact Resistance. For high-performance applications, ensure the pins can handle the required current without overheating, typically ranging from 1A to 10A. Contact resistance should be kept low (usually <30mΩ) to ensure signal integrity. Additionally, evaluate the Spring Force (measured in grams) to ensure reliable contact without damaging the mating surface, and verify the Mechanical Life Cycle, which should ideally exceed 10,000 to 1,000,000 compressions depending on the application.
