Are there any good online resources for sealing (dustproofing and / or waterproofing) available online? I'm wondering about USB micro connectors, but also just in general, what do people do to seal connectors.
A fair point - I guess what I meant was that I want to seal connectors when space is a factor - so if the connectors are soldered directly to the PCB, how is the space between the connector and the plastic case sealed?
Check out the Molex Part No. 105443. It appears to be a standard PCB mount USB connector, but with a rubber seal (to seal against the enclosure opening) and is IP67 rated.
