Thermal Chambers - Cable Notches

Cable notches make it easy to load a  "wired" DUT (Device Under Test) into and out of the chamber. The ability to load and unload fully configured DUTs is not only a convenience, but a health and safety benefit as well, as opertors don't have to spend time bent over with their head in a chamber while attaching cables, pipes, or monitors to the DUT. Cable notches work equally well with flexible wires or rigid fixtures.
If you move loads attached to wiring, hoses, etc. in and out of the chamber often, the best option is often a "notch" at the front door edge of the working cavity where the door closes. Door notches allow loads to be moved into or out of the chamber without detaching having to release connections.
