  • Spring: SUS304
  • Plastic: Polyamide (PA) or Liquid Crystal Polymer (LCP)

Magnetic pogo pins connectors , also known as spring needle contacts, spring charging contacts, charging conductive pins, or top pins, are primarily used in the connection of electronic products. The following details explain the specifications and material choices further:

  • Rated Current and Voltage: These are the maximum current and voltage that the Pogo pin connectors are designed to handle safely. Customization is possible based on the specific requirements of the application or the client.
  • Contact Resistance: This refers to the resistance encountered when current passes through the contact point of the connector. A lower value indicates better conductivity. The distinction between through-hole and blind-hole contact resistance is important for design considerations.
  • Life Test: This measures the durability of the Pogo pin connectors by simulating the number of connection and disconnection cycles they can endure before failing. The standard is 10,000 cycles, but this can be adjusted according to the demands of the application.
  • Spring Force Requirements: The spring force determines the stability and reliability of the connection. Signal pins require a minimum spring force of 60 grams at their maximum working height, while power pins require at least 90 grams.
  • Salt Spray Test: This test measures the resistance of the Pogo pin connectors to corrosion. The duration of the test (48H, 72H, or 96H) indicates how long the connectors can withstand a corrosive salt spray environment.
  • Solderability: The reference document EIA-364-52 provides standards for the solderability of electronic connectors, ensuring that they can be effectively soldered into a circuit without compromising their performance or reliability.
  • Vibration Test: The random vibration test, following EIA-364-28 and tested under condition II, assesses the Pogo pin connectors’ ability to withstand vibrations that may occur during transportation or operation.

Material Selection:

  • Pin Tube and Tip (Brass): Brass is chosen for its excellent electrical conductivity and corrosion resistance, making it ideal for the conductive parts of the connector.
  • Spring (SUS304): Stainless steel is used for the spring due to its strength and resistance to corrosion, ensuring the spring maintains its elasticity and performance over time.
  • Plastic (PA or LCP): Polyamide and Liquid Crystal Polymer are chosen for their high strength, dimensional stability, and resistance to high temperatures, which are crucial for the structural integrity and durability of the connector’s plastic components.
