The norm is dedicated to connectors with rated voltage above 50V and up to 1000V and rated currents up to 125A per contact. But
depending of your application connectors should be compliant with another standard. This has to be double checked with the customer.
There are lot of constructional requirements and performances specifi ed in that standard. Most of them are illustrated in greater details
hereafter.
Provisions for earthing:
The UTS connector is intended to be used on Class II systems. Even if the purpose of our connector is not to interrupt current, we often
see a need to add a protective earth contact. Then this one shall be a “First mate, last break” style. Critically, among all of the normal
assumptions we make in designing a connector, this contact has to be considered as a live part and must be protected against electric shock
by double or reinforced insulation.
IP Code:
IP is a coding system defi ned by the IEC 60529 to indicate the
degrees of protection provided by an enclosure. The aim of this is to
give information regarding the accessibility of live parts against ingress
of water and other foreign bodies.

UTS offers high sealing
performance IP68 / 69K…
Even in dynamic situations.
In addition to the IEC 60529 we conjointly use the DIN 40050 part 9
which are dedicated to road vehicles. The main differences are:
• First digit: 5 replaced by 5K, 6 by 6K. In the DIN the tested
equipment is not depressurized as it is in the IEC.
• Second digit: 5K and 6K has been added and are equivalent
respectively to 5 and 6 but with higher pressure.
9K which represents the High pressure cleaning.
