Belden PH163, Volex 17952, Alpha 544

Thank you for looking 

 It was used extensively by Hewlett-Packard and many other manufacturers in the 1960's. The earliest instances of use I have noted are on a HP-3440A DVM from 1965 and a Friden SBT10 mechanical calculator, manufactured in 1964 but introduced in 1959. Connectors of this type were still being installed on new equipment up to at least the late 1970's. Some documentation indicates the cord outlet was designated as PH-163.  Belden manufactured cordsets with these connectors.  Perhaps it was a Belden design that they successfully marketed to many equipment manufacturers, to become a de-facto standard.  Polarisation: Somehow the 163 connectors ended up being used with both possible orientations of the Line and Neutral connections, as indicated in the photo. Earth managed to stay in the middle. All the instances of use in Hewlett-Packard and other equipment I have run across are connected one way, consistent with the Belden 17952 cordset. Of course, UL and CSA had to designate the opposite way, reflected in the Belden 17280 cordset. How much of a crisis this is depends upon how much of a stickler one is for such safety issues. It is primarily a concern when servicing or working inside equipment, it is not likely to be an issue for basic operation.
