Re: Looking for a connector

Mr. V,
You are correct in that it is not a 65 degree rise specification. What the 65 degrees refers to is the UL standard of maximum current based on 65 degrees measured at the contact. This temperature is chosen as the reference point based on the failure temperature of the plastic body less some derating for safety. The connector can withstand continuous 45 amps forever under this test. I believe that the pulsed data is relevant for this connector based on general use in FRC robots and the addition of the circuit breakers that are in place. I cannot comment on the reported failure earlier in this thread. There are a number of factors that could have contributed to the failure beyond simply current.
