Designed for the automotive industry, AMP SUPERSEAL connectors meet the sealing requirements outlined in IEC 529 and DIN 40050 I.P 6.7 specifications. The cap and plug connector housings incorporate preassembled secondary locks to help insure correct and complete contact insertion into the housing and helps prevent the contacts from backing out during mating. The secondary lock cannot be closed if the contacts are not correctly inserted into the connector housing. Cavity plugs are available for sealing unused connector cavities. The double spring contact design (main spring and auxiliary anti-overstress spring) insure low insertion and high contact forces.
