Technical characteristics Type H
Current carrying capacity
The current carrying capacity is limited by maximum temperature of
materials for inserts and contacts including terminals. The current
capacity curve is valid for continuous, non interrupted current loaded
contacts of connectors when simultaneous power on all contacts is
given, without exceeding the maximum temperature.

Low currents and voltages
Type H standard contacts have a silver plated surface. This pre-
cious metal has excellent conductive properties. In the course of a
contact’s lifetime, the silver surface generates a black oxide layer
due to its affinity to sulphur. This layer is smooth and very thin and
is partly interrupted when the contacts are mated and unmated,
thus guaranteeing very low contact resistances. In the case of very
low currents or voltages small changes to the transmitted signal
may be encountered. This is illustrated below where an artifically
aged contact representing a twenty year life is compared with a
new contact.
In systems where such a change to the transmitted signal could
lead to faulty functions and also in extremely aggressive environ-
ments, HARTING recommend the use of gold plated contacts.
Below is a table derived from actual experiences.
