The plug shell is designed to be fitted with inserts for size 22 pin contacts and inserts for socket contacts for all other contact sizes. The plug shell has a field replaceable EMI spring and a coupling seal on each shell cavity and 3 polarization posts. The receptacle shell is designed to be fitted with...

How to Order Insterts Inserts are made of the thermosetting resin, high grade thermoplastic or of aluminium alloy. They have metallic retention clips to retain the contacts. Each insert has one polarization slot which has its corresponding pin in each shell cavity. Environmental inserts have: A) a silicon rubber ring that ensures sealing between the insert and the shell. B) a rear grommet which ensures sealing around each wire crimped on a contact. C) an interfacial seal which ensures sealing around each protruding contact once the connector is matted. Non environmental inserts do not include...
