Type «AZ» is the standard version of the WDE. The flange side mates with an «A» type plug, and the threaded side mates with
a «Z» type plug.
In the inverted type «ZA» of the WDE the contact block is mounted in the opposite direction. Therefore it mates with a type «Z»
plug at the flange side and with a type «A» plug at the threaded end (see also page L4).
While both sides of the WDE are equipped for self-latching, only the flange side contains a sealing O-ring in the mating area.
Whether sealed plugs must be used depends on the application. Sealed plug are not required when the connectors are not
exposed to environmental conditions requiring protection.
Fixed connectors
The fixed connector types DEE, DBEE, DBPE, SFE and WDE meet all requirements for sealing at points a, b and c listed on
page M1. They are hermetically sealed even in unmated position, whether mounted or not. However, proper mounting in a
bulkhead with a smooth and flat surface is a prerequisite for proper sealing to an enclosure.
Free connectors
The plugs S and WSO are sealed at points c and d, page M1, but the sealing is only effective when connected to a connector
with interface o-ring c.
To seal properly at d, the cable diameter must match the cable collet and sealing ring. The cable jacket must also be cylindrical
and smooth.
Protective covers for sealing of unmated, free connectors are available and come complete with an O-ring seal.
However, if the contacts must also remain accessible for steam or chemical sterilization, the connector must be potted with an
elastomer such as silicone elastomer in order to avoid liquid or steam penetration.
For the sealed cable receptacles KE, DKE and DKBE, the same conditions apply as described above for S and WSO.
Pressure Differentials
Our standard hermetically sealed, fixed connectors will
withstand a pressure differential of at least 8 bars, or 0.8
MPa according to SI-System. However, a greater differential
can be obtained if the higher pressure is on the solder side
of the receptacle.
In order to determine the highest possible pressure for a
particular type of connector, please contact us.
