Feedthrough cable product brief

Cable batch polarity test

This test was inspired by the incorrect polarity cable that we received in multiple batches. It was type B, while in the second purchase it was a mix of type A and type B. The specs on the order do not say anything. in the next order, we need to explicitly state that we want TYPE A (Straight - Not cross) as we are adopting is a standard for couple configuration in the detector.

...

Results of testing all cables are as follows

If a type B cable is used, you need a straight coupler (both keys are on one side). 

If a type A cable is used, you need a cross coupler (one key on one side, and the other on the other side).
