High density signal connectors for hydrogen applications (Han® DDD)

  • The need for space-saving solutions is a fundamental theme which prompted HARTING’s development of the Han D® Series, which stands for high contact density and small dimensions.
  • The Han® DDD has twice the number of contacts than the previous standard Han® DD – yet retains the same dimensions and electrical characteristics.
  • The electrical power is equivalent to that of its sister product, the Han DD® (max. 250 V / 10 A).
  • Han® DDD inserts can also help optimize wiring processes and the use of interfaces in conventional control cabinets.
  • The new triple “D” inserts are standing for maximum contact density – up to 130% plus, compared to previous standards – without reducing the rated voltage.

Connectors guide with all variants

  • Introduction
    • The Han® DDD connectors are available in large number of variants. For details see Han® DDD guide – click here.
    • Available from size 6 to 16B
    • The “Triple D” can transmit signals or power with max. 107 contacts
    • The connector series Han DDD®, Han DD® and Han D® equipped with all contacts may be used for voltages up to 250 V, pollution degree 3.
    • A modified contact loading arrangement permits use up to 500 V also in the same pollution degree.
    • According to DIN EN 61984 connectors should not be coupled or decoupled under electrical load.
