Features
• Combination of power and signal area in one con-
nector
• Crimp termination for power and signal area
• Use of standard Han E ® and Han D ® contacts
Removal of power contacts (Han E ® )
➀ Push cross-slotted screw driver ( size 0 acc. to DIN 5260) in the
relevant hole of the contact until it reaches the bottom
➁ Withdraw the crimped contact from the insert
Removal of signal contacts (Han D ® )
Description see removal tool chapter 99
Current carrying capacity
The current carrying capacity of the connectors is limited by the
thermal load capability of the contact element material including
the connections and the insulating parts. The derating curve
is therefore valid for currents which flow constantly (non-inter-
mittent) through each contact element of the connector evenly,
without exceeding the allowed maximum temperature.
