The panel-mount connectors consist of a contact insert for the PCB mounting and the connector housing. The assembly of both components happens by mounting the PCB into the housing furnished by the customer. Between the connector housing and the insert there had so far been no possibility of applying a sealing which could have been lead to problems in the case of an improper use of the devices in a non-connected position in a wet area.

Now the parts have constructively been modified in a manner that an O-ring may optionally be mounted which should avoid the entry of moisture in the case of a fault. The O-rings weren`t included with the previous versions. In case of any demand we have now the possibility to furnish the new version with O-ring. At the male version an O-ring has been integrated into the plastic part and at the female version the housing has been modified in a manner, that the O-ring may ensure a sealing to the plastic body.

These modifications do not influence the functionality. Till now the connectors are IP67 tight both in a connected and locked condition - the new solution ensures this as well. The modification is effected step by step. During this period mixed deliveries may occur. The prices are not affected by this modification.
