Applications

The D38999/26ME35PB is a cable-mounted straight plug on the E-35 insert — 55 contacts at size #22D in shell size 17, the highest-density arrangement for that shell. The M finish is electroless nickel, which is cadmium-free and gives a conductive, corrosion-resistant surface for industrial and commercial builds where olive drab cadmium is not wanted. The trailing B is the key position: a B-key plug will only mate with a B-key receptacle on the same panel, so an identical shell and insert can still be polarised against mis-mating.
