Schurter has some power entry modules with a .01 suffix. What does this callout?
Part numbers 5707.0603.313 Digi-Key part number (486-1273-ND) and 5707.0603.313.01 Digi-Key part number (486-6256-ND).
The .01 will callout that the part comes with a Gasket to make the part IP54 rated. That is the only difference.
