LED Polarity Testing Procedures and Equipment


Xmultiple's Engineering Department

LED's have a positive side and a negative side, and will only light up when wired correctly. Most LED's have one longer lead to indicate the polarity, however once LEDs are integrated into Xmulitple RJ connectors these leads are the same size. It is important that you determine the LED polarity you require for your product before ordering Xmultiple LED RJ connectors. The diagram below shows the positive (+) and negative (-) information you need to look at in our drawings to make sure the polarity is correct and will meet your requirement.
