Contact
The precision engineered power contact type 101
is characterized by a turn-able bearing, thus
uncoupling cable and contact. Consequently any
occurring bending forces can-not affect the
stability of the contact.
The mechanical stabilisation is taken over by the
supporting plate whereas the contact fingers
ensure positive electrical contact. Contact fingers
are silver plated.
The contact design has been verified and
exceeds the requirements of IEC 61439-1/-2.
Tests:
Design verified acc. IEC 61439-1/-2
Corrosion test acc. DIN 50017 and IEC
60068-2-60
Crimping quality check acc. IEC 61238-1
Vibration and shock test acc. IEC 60068-2-6
and IEC 60068-2-27
Further on during manufacturing each single
contact is subject to a particular routine test
screening its function and contact force.
