    Purchase a touchscreen monitor on ebay and recieved it with two three pin female plugs on back of monitor. One marked 5v the other 12v. Looks like there is a male match to this this three pin plug but not common. looks like what you typically find inside a computer. Any clues to what this is? See attachment...

    Most likely these two connectors are the dc power to the touchcscreen. It is difficult to tell whether you need to apply power to both or possibly one or the other. The 9-pin d-sub connector pictured in the left of the shot is probably the serial output of the touchscreen data.

    The two three pin connectors appear to be of the type made by "phoenix contacts". Their website is www.phoenixcon.com. I think you can purchase the mating connectors from Digikey at www.digikey.com. Beware, these connectors come in several different pin to pin spacings so select the mating connector with care.

    If in doubt you can always contact the ebay seller and ask for information on the correct usage of the connectors.

    Good Luck,
