Enclosure Waterproof Test - Blog 2

charlieo21

For the initial test, I did put all the connector in the enclosure.

This test is to check how good is the waterproofness on the Hammond enclosure.

I wasn't able to get the threaded inserts for the RJ45 hood, so I decided to use J-B Weld for keeping the hood attached to the enclosure.

I put a humidity sensor inside the enclosure to check the humidity inside and be able to identify  water ingress.

The sensor was connected using the 4 pin connector to my laptop, I log a measurement every second.

I put the enclosure in a plastic container and I added water until the Hammond enclosure was all submerged in water.

After running the test for more than 2 hours, I checked the graph and I saw a humidity increase around 40 minutes.

I found that the water ingress was happening in the 4 pin connector.

Because I was using that connector for the humidity sensor with a cable that wasn't meeting the diameter specification on the connector the waterproofness wasn't achieved.

It was my fault and I'll use a proper cable for the following experiments.

All the other connectors achieved the waterproofness needed to pass this test.
