I am trying to recycle some sensors I had with an old Lego RCX.· I have a "Short Range Dual Infra Red Obstacle Detector" from a 3rd party vendor and they were nice enough to provide some pin-outs for me, however, I am unfamiliar with some of the terms.

Pin 1 is labeled NC
Pin 2 is labeled VCC
Pin 3 is labeled Ground
Pin 4 is labeled Right Signal
Pin 5 is labeled Left signal

Pins 3, 4, and 5 are pretty straight forward, and I was able to deduce that pin 2 is probably supposed t go to Vdd, but I have no idea what NC (pin 1)·means..?· I've included an image of the pin-out diagram that the vendor gave me (not sure if this is helpful or not).· I realize there are probably going to be many differences running this· with my BS2, but any help would be appreciated.· Thanks!!

    NC = Not Connected.

    As PJ says, "NC = Not Connected" except in a case where you might have a relay providing some sort of switched output.
    In that case NC would mean Normally Closed.· The complement of that would be NO meaning Normally Open.
