Product Description
Ingiant pneumatic slip ring DHK035-6-2Q integrates electrical circuits (power/signal) with pneumatic/hydraulic passage for continuous 360° rotation. The unit has a compact through-hole design for shaft mounting and supports data and fieldbus standards including Ethernet, EtherCAT, Profibus, Profinet, CANbus and DeviceNet. Key options (number of circuits, housing material, IP rating, rotational speed, cable length, connector type, special cables, salt-mist protection, temperature range) are configurable. The housing can be mounted inverted.
