ITT Cannon provides a breadth of robust connector options, including their Trident Neptune Metal (TNM) series. Many of these connectors use dissimilar contacts, with large power contacts and smaller signal contacts. TNM6S14-0304P1L is a good example,with four signal contacts and three power contacts. The Associated Product listing for this connector shows all its associated contacts, but how do you know which ones are the power and which are the signal?
In this specific device’s case, ITT has confirmed that the APK series part 031-8717-020 is the power contact for TNM6S14-0304P1L/2643121. As a rule of thumb, search for the APK-series product in the Associated Contacts listing for this series to find your power contacts. All the other contacts presented will work for the Signal lines, leaving you plenty of options to choose from.
