IP65 compliance for plastic enclosure (Design rules required for Cutouts for USB, SD card port etc)
I am interested to know any specifications or any text which gives me design rules to prevent water and dust entry into enclosure through cutouts given for USB poart and SD/MMC connectors.
The easiest way to achieve this is to purchase panel mount connectorss that meet or exceed IP65 and example of a usb one is Amphenol MUSB-A511-00. The SD card may be harder to find. You could also try to design a cover for the SD card slot... something with an o-ring and proper fasteners comes to mind. There's no writtn out way on how to design to meet IP standards. You just have to come up with create solutions and then follow the testing standards described by the IP standard to see if they work. http://en.wikipedia.org/wiki/IP_Code
