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...
