Inductive couplers

Contact-less transmission of power and data

Fixed wiring of sensors and actuators has its disadvantages. Cables and contacts are frequently heavily stressed in automation so that cables can fatigue and break, thus resulting in a often costly unplanned downtime.

Balluff portfolio of inductive couplers offer unique contact less solution to transmit data and power across an air gap. Thus, no mechanical wear to worry about. The system availability is higher, the cycle times are shorter, the sequences are more flexible. The units can quickly be disconnected, are easy to handle and maintenance-free. enabling you to meet new demands quickly. As the inductive couplers are IP67 encased devices they are practically immune to water, dust and any other debris in the environment. The data transfer uses magnetic induction- even a barrier between the transmitter and receiver does not stop the data flow.


  • No mechanical wear
  • Higher system availability, shorter cycle times, more flexible sequences
  • Quickly disconnect, easy to handle, maintenance free

  • Inductive couplers for IO-Link signal transmission

    Transparent, contactless data exchange between master and device

    Inductive couplers for IO-Link signal transmission are used for non-contact transmission of power and data over an air gap. This renders mechanical plug-in contacts superfluous. When using our bi-directional coupling system with IO-Link, data exchange in both directions is possible.

    The contact-free signal transmission on IO-Link Standard is transparently structured: the system performs "invisibly" and does not have to be configured. You can very easily integrate it between IO-Link-Master and IO-Link-Device to communicate immediately.

    The system has a complete IO-Link interface, regardless of the IO-Link version. Events, parameters, and process data are exchanged directly between the master and the device.


    • Simultaneous control of actuators and gathering of sensor signals
    • AUX power for actuators can be switched on and off
    • No configuration needed – simple installation via plug-and-play
    • IO-Link functions through to the device
    • Flexible process data length

  • Inductive couplers for signal transmission

    Reliably transmit signals in both directions

    Our inductive couplers for signal transmission are designed for up to eight sensor signals and eight actuator control signals.

    The system is bi-directional, transmitting signals in both directions. Its remote unit can drive on an individual basis and operate clamping units. From the base, up to eight signals are transferable, and four channels can be controlled independent of each other.


    • Send signals in both directions
    • Remote unit drives on an individual basis and operates clamping units
    • Transfer up to eight signals
    • Drive four channels independently of each other

    Contactless power transmission guarantees fast format change

    Fast format changes ensure high productivity. These are often made substantially more difficult by plug-in contacts, such as when changing grippers on a robot.

    Our inductive couplers for power supply transmit power contactlessly across an air gap. Mechanical plug contacts are therefore superfluous. The advantages: Non-wearing, rapid tool changing and great flexibility.


    • Wear-free – contactless power transmission across an air gap
    • Prompt tool change
    • High flexibility
