4mm Micro Magnetic Pogo Pin Connector (Circular Charging Port)

Advanced Plating & Material Features

• Ultra-Miniature 4mm Design:
  Specifically developed for next-generation micro-electronics, offering a minimal footprint for the most space-constrained designs.
• High-Performance Pogo Pin Technology:
  Features precision-engineered, gold-plated spring pins that ensure reliable electrical conductivity and consistent contact force.
• Strong Magnetic Self-Alignment:
  Despite its tiny 4mm size, the integrated high-grade magnets provide a powerful self-centering force for easy and secure "blind mating."
• Dust & Water Resistance:
  The low-profile circular design is easy to clean and can be integrated into enclosures to provide basic dust and moisture protection for internal components.
• Exceptional Durability:
  Built to withstand over 10,000 mating cycles, ensuring long-term reliability for consumer and industrial port applications.
