I was contracted to build a breakout box for thermocouples used in monitoring the temperature of blood storage.
See images below.

The thermocouple probes.


I had to terminate them with Switchcraft® brand 4 pin mini XLR male connectors


Size reference for the connector body.


Soldering the thermocouple cable to the male connector.


Thermocouple wire is typically a bi-metal, this one was particularly hard to solder. I used rosin based flux and set my iron to 800° F.


Lots more to do. In all I had to terminate 20 thermocouples, make 20 16' male to female extensions, install and wire 20 female panel mount connectors and terminate the back ends to a data card.


The breakout box complete with cable gland.

So is this (to dumb it way down) basically a snake for thermometers?

Sure, as you well know we've called small snakes breakout boxes.

Yeah I know but when I think breakout box, computer interfaces is always what I comes to mind.

That's pretty much exactly what it was!
