Common waterproof ratings are IP65, IP66, IP67, IP68, and so on.
If working in extreme humidity or underwater, IP68 is recommended to ensure the reliability and stability of pin connectors,
At the same time, we need to consider the water pressure and water temperature.

pin connectors_5.2_magnetic waterproof connector

How to realize IP65, IP66, IP67, IP68?

Waterproof sealing is the key to IP68,
Rubber sealing ring is designed between the housing of pin connectors and device shell.

pin connectors_5.7_magnetic waterproof connector

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.

Material selection of pin connectors

Brass is recommended, but phosphor bronze, beryllium copper can also be used, when a very high number of insertions and removals, and a long life-cycle are required.
Brass, containing 25~35% zinc, or containing 35%~45% tin, best suited to room temperature processing, although it is a good conductive material, it is easy to deform and fatigue quickly after repeated bending.
Pin connectors with brass contacts should not preferred where excellent flexibility is required.
