Apparatus for electronic component and heating cable mounting
A mounting rail is provided that includes a DIN rail and one or more heating cable channels. A channel defined by the DIN rail may include one of the heating cable channels. Heating cables may be installed in the heating cable channels using adhesive and/or heat transfer material to form an electronics heating module. The heating cables may be self-regulating heating cables. The mounting rail may include multiple heat transfer fins that transfer heat generated by the heating cables to environment surrounding the mounting rail. A terminal block may be mounted on the DIN rail and may supply electric power to the heating cables.
