Do you have any files that indicates the shelf life of your connectors ?

We do not give any shelf life for our connectors since it depends on the mating cycles. For instance, for a standard TV connector, the mating cycle is 500. For a composite connector « CTV » fitted with « H » and « J » contact types, it’s 1500 cycles.

What kind of contacts are available for standard MIL-DTL-38999 connectors (or EN3645 connectors)?
  • Crimp contacts:
    These are the most common contacts used with this type of connectors, and described in MIL-DTL-38999 and EN3645 standard for environmental connectors.
    When crimp contacts are delivered with connectors, they are not mounted into connector insert. 
     
  • Crimp contacts:
    We do not give any shelf life for our connectors since it depends on the mating cycles. For instance, for a standard TV connector, the mating cycle is 500. For a composite connector « CTV » fitted with « H » and « J » contact types, it’s 1500 cycles.
    When crimp contacts are delivered with connectors, they are not mounted into connector insert. 
     
  • Solder contacts: hermetic connectors only are equipped with solder contacts (solder cup or eyelet contacts).
    Additionally Amphenol has developed enhanced sealing connectors which can be equipped with solder cup contacts (only available in proprietary Amphenol designation).
    Solder contacts are always supplied already mounted into connector insert.
     
  • PC tail contacts: Amphenol has extended contact type range, proposing also PC tail contacts for PC board applications. PC tail contacts are available in different tail length and tail plating. Connector delivered with this type of contacts are only available in Amphenol proprietary part numbers, and PC tail contacts are already mounted into connector insert. 
     
  • Wire wrap contacts: available in proprietary connector part numbers, please consult us.
     
  • Press-fit contacts: not available in standard.

Can all MIL-DTL-38999 connectors accept backshells?

All types of plugs and receptacles can accept backshells, except box mounting receptacles (LJT02, LJTP02, JT02, JTP02, TVP02, CTVP02), which do not have any thread at the rear of connector. 

Each backshell can be used on both plug and receptacle of the same connector range and size (ex: TV NSA 15 014 can be put at the rear of both TV06RW1535P and TVP00RW1535S or TV07RW1519P)
