These socket and coupler models allow the device on which they are fitted to reach a protection index of IP68 as per IEC
60529. They are fully compatible with plugs of the same series and are widely used for portable radios, military, laboratory
equipment, aviation, etc.
These models are identified by a letter «P» at the end of the reference.
Most of these models are also available in a vacuumtight version. Such models are identified by an additional letter «V» at
the end of the part number (certificate on request).
Epoxy resin is used to seal these models.
