IO-Link enables perfect linear feedback

Non-contact, wear-free magnetic field sensors for indicating end-of-travel and intermediate positions have long been a standard in pneumatic automation technology. They reliably detect the actual position in both pneumatically powered actuators such as cylinders and grippers and in special pneumatic applications such as on screwdrivers, maintenance units, motors, tensioners and slides.

Because of their capability of increasing digitalization of automation technology, more intelligent, networkable pneumatic actuators are in demand. For one thing, the piston travel needs to be continuously monitored so that automated position setting can be achieved. For another, it should be possible – beyond the actual process data – to obtain comprehensive service and diagnostics information.

Our magnetic field positioning systems and sensors with IO-Link meet this specification completely. This intelligent technology provides all the desired data and ensures perfect linear feedback. It turns your pneumatic actuator into an optimal IIoT solution which moves you to the front row of digitalization in pneumatic drive technology.

Application examples

  • Monitor positions and processes in a fastening system

    Using BES inductive sensors for hoses, BMP magnetic field positioning systems and BMF magnetic field sensors

    As screws are fed, our BES inductive tube sensors monitor each individual screw. Our BMP magnetic field positioning systems monitor the screwing process by continuously measuring the feed while the screw is being turned. And our BMF magnetic field sensors check for correct end stopping of the screwing unit.

    Features

    • The right sensor technology for each function
    • Intelligent sensors use IO-Link to make the screw system IIoT-capable
    • IO-Link reduces setup times since the parameters are set in the controller

  • Monitor positions in pneumatic slides

    With BMF magnetic field sensors

    You can use our compact magnetic field sensors in pneumatic slides to monitor the slide position without contact. The wear-free, compact sensors feature great holding force and are highly reliable even at fast traverse speeds. There are also single-connector versions for two sensors. They are available in M8 and M12 to save plug space. This is an economical solution that reduces your assembly and wiring effort and expense.

    Features

    • Precise switching point for reliable position detection
    • Versions for flush mounting in C- or T-slot
    • For space-critical applications, can be inserted from above
    • Impervious to contamination
    • Universal slot nuts reduce number of different versions

  • For perfect integration in grippers and slides

    With BMF magnetic field sensors with IO-Link

    Especially on grippers, where space is extremely valuable, you can use our intelligent magnetic field sensor to define and check up to eight switching points within the sensor's working range. And this digital solution lets you set the hysteresis individually for each switching point.

    As a result, up to eight different object sizes can be detected in one gripper, thus making the use of several conventional sensors superfluous. This means significantly more comfort for you as well as greater flexibility and cost savings.

    Features

    • Extremely large, 60 mm travel path
    • Sensor head length 20 mm, with remote electronics – ideal for compact applications
    • Remote teaching of up to eight switchpoints via IO-Link
    • IO-Link PNP NO
    • M12 and M8 sensor with cable and plug, M8 sensor with 2 m cable available
    • Temperature range –25...+80°C
    For perfect integration in grippers and slides

  • Monitor piston position on cylinders

    With BMF magnetic field sensors

    Our compact standard magnetic field sensors are the optimal classic solution for monitoring the piston position on cylinders. The sensor recognizes the field of the magnet integrated into the piston through the actuator wall, even at high travel speeds. With its non-contact position detection these magnetic field sensors from Balluff are absolutely reliable and wear-free. This means: no contact erosion or bounce. You get only clean switching points.

    Features

    • Can be installed in T- or C-slot from above
    • Short, compact form factors with great holding force as well as miniature sizes for short stroke cylinders and grippers
    • No double switching points
    • Large, extremely bright LED for simple diagnostics
