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.
