Original label - verify the supplied unit: The original listing label reads NMB-MAT 1604KL-04W-B39, 12V DC, 0.09A, with the B22 marking. Image 1 retains the original angled rear view, visible side-frame marking and three-wire bundle. These are photographic observations, not measurements or confirmation of the unit that will be shipped. Supplied dimensions, mounting, full connector and pinout require verification before ordering; wire colors and visible count do not establish signal functions.

External reference photo - verification required: Image 2 is an external supplier photograph from ElecSpares, showing NMB-MAT 1604KL-04W-B39, 12V DC, 0.09A, with the B22 marking. It is a different photographed unit and does not confirm current shipping stock. Original image 1 retains the original listing nameplate, side-frame marking and visible three-wire bundle. The wire ends are outside the reference frame; neither visible wire count nor color establishes the supplied connector, pinout or signal functions. Confirm the actual offered label, dimensions and connection before ordering.
