  • Sealing glue fills voids and gaps between pogo pins and the housing and form a waterproof barrier.
  • O-ring, its special shape allows it to form a seal under pressure, preventing water penetration.   

Water-resistant Coatings Are Another Important Component of IP68. 

  • Silicone coating is usually applied to the surface of the housing by spraying or dip-coating to form a waterproof film. It is effective in preventing moisture penetration, and has excellent resistance to high temperatures and corrosion. 
  • Liquid Waterproof Coating, It fills the gaps and crevices of pogo pin connector by itself, forming a continuous waterproof film.
  • Nanocoating is a very thin coating material with excellent waterproofing properties. It consists of nanoparticles that fill the tiny pores on the pin connectors to form a continuous waterproof film.
