WATERPROOF POGO CONNECTORS
Updated: Oct 19
Pogo-pin connectors became very popular in the field of charging devices. Lately, you can find them also in an outdoor applications. Outdoor environment requires a special design, mainly to protect the contacts against humidity, water & salt spray.
Protecting the pins & the entire connector against water is the main issue in the connector’s design.
You may protect the internal mechanism of the pin (if necessary) by applying an o-ring between the plunger and the barrel.
The protection between the pogo and the plastic frame is done either with an elastomer material or, an individual o-ring around each pin.
At least one side of the connector should have a sealing gasket around it.
An EMI gasket can be chosen—if needed.
The external body coating and specially the plunger coating is a critical issue. Our advice is to use a minimum of 1.5μm hard gold plating over 1.3μm nickel plate.
