Hi Chip,<br>
<br>
Watertight bulkhead fitting (such as the ethernet gland) and rather
than a connector inside the box, use a terminal strip. You can crimp
on ferrules to keep the strands from straying (or just tin them). <br>
<br>
The $7.95 each is a bit high;

shows pretty much the same item for a LOT less. Looks like a 3/4"
hole (NTP pipe thread) ... if this is too big, look at the plastic
plumbing compression fittings in the hardware store. As long as your
cable has the same relative outside diameter as the tubing for the
compression fitting (copper or plastic) you should be ok. <br>
<br>
Here's a better solution, 3/8" NTP thread, for smaller cables, less
than $1.00 each.<br>

Hope this helps.<br>

To all,
<div><br>
</div>
<div>I have been using Pelican boxes for my outdoor projects as
they provide IP67 protection (dust and immersion up to 1m for
some period at least). The problem is that I need to connect my
board inside the box to the sensor outside. So, I have been
drilling a hole in the side and passing the wire through, then
terminating both ends (6 pins) and sealing with either hot glue
or silicon calk. There are two problems with this approach: </div>
<div>1) I can’t take the cabe out if I want to use a different
sensor or a different length of cable</div>
<div>2) Over time, the movement of the wire opens gaps that let in
water.</div>
<div><br>
</div>
<div>So, I have been looking for a solution. Here is what I have
tried so far:</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>-
Better and more glue and caulk - not much luck and still have
issue #1</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>-
The <a moz-do-not-send="true"
href="https://www.hirose.co.jp/cataloge_hp/e13000041.pdf">Hirose
HR-30 waterproof connectors</a> - very cool but expensive ($14
a pop - more than the Pelican case) and a real pain in the ass
to solder</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>-
Adafruit has a cool waterproof <a moz-do-not-send="true"
href="https://www.adafruit.com/products/827">Ethernet gland</a> but
it is too big and bulky for the case (will bring on Monday in
case you need one).</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>-
Adafruit also sells some <a moz-do-not-send="true"
href="https://www.adafruit.com/products/762">smaller glands</a> which
are my lead candidates though they don’t solve issue #1.</div>
<div><br>
</div>
<div><br>
</div>
<div>So, if you know of a 6 connector solution that is small,
cheap and waterproof - I would love to hear your thoughts.</div>
<div><br>
</div>
<div>Thanks,</div>
<div><br>
