Note
Assimilation of color coding for cable ZB9030, ZB9032 and ZK1090-3xxxx-
xxxx (with M8 connectors)
For unification the prevalent cables ZB9030, ZB9032 and ZK1090-3xxx-xxxx this means
the pre assembled cables with M8 connectors were changed to the colors of EN61918 (yel-
low, orange, white, blue).So different color coding exists. But the electrical properties are
absolutely identical.
EtherCAT connectors
The following connectors can be supplied for use in Beckhoff EtherCAT systems.
