Detect Piston and Valve position in Hydraulics
Detect Piston and Valve position in Hydraulics

For perfect integration in the pressure area

High pressure rated inductive sensors from Balluff are perfect for position monitoring of your hydraulics, for example, end-of-travel checking on hydraulic cylinders or monitoring valve positions. Installed directly in the pressure area, these sensors withstand pressures up to 500 bar.

And with a temperature range of up to 120 °C and a switching distance of up to 2.5 mm, they have universal application. Using the optional temperature output you can also protect the cylinder from overheating.

To handle position monitoring with non-magnetic cylinders, choose our universal magnetic field sensors.

Application examples

  • End of Cylinder Stroke Detection

    With BHS pressure-rated inductive sensors

    High pressure-rated sensors are the established standard for end-of-travel monitoring on hydraulic cylinders. These detect the end position of the stroke in hydraulic cylinders without contact and wear-free. By using the sensor for end position damping you significantly increase the reliability of the axis. To handle high forces even when space is at a premium, choose our high pressure rated M5 and M8 sensors.

    Features

    • Reliable standard for up to 500 bar
    • For any cylinder or valve size – versions from M5 to M16

  • Electronic End Position Damping

    Using BAW high pressure-rated inductive distance sensors

    High pressure-rated inductive distance sensors from Balluff detect those last millimeters before the end stop with high precision. Their analog 0 to 10 V signal is ideal for electronic end position damping. These sensors are easy to integrate for reliable monitoring of the valve position. The conical actuation element expands the measure range, making them flexible when it comes to installation.

    Features

    • Analog signal 0…10 V
    • Easy to integrate
    • Pressure-rated up to 500 bar

  • Monitor End Positions on Tie Rod Cylinders

    With BHS pressure-rated inductive sensors with fixed stop

    For precise end-of-travel monitoring on hydraulic cylinders choose our pressure-rated inductive sensors with fixed stop. This end stop makes simple installation possible. You also benefit from great freedom of design because the pressure-rated housing swivels, allowing you to position the cable exit as needed.

    Another plus: A wide range of sizes lets you select the right sensor for your cylinder type.

    Features

    • Fixed stop and pressure-rated housing for ease of installation
    • Cable and connector exit can be ideally positioned thanks to swivel housing
    • Established US standard – supports systems builders in international competition

  • Detect Positions in Non-Magnetic Block Cylinders

    With BMF magnetic field sensors

    Varying piston positions can be reliably detected from the outside on block cylinders made of non-magnetic materials such as aluminum or stainless steel because our magnetic field sensors detect both end positions and intermediate positions. Thanks to IO-Link you can even define up to eight switching points. These universal sensors detect the permanent magnet ring attached to the piston through the cylinder wall.

    Features

    • Detect end and intermediate positions – universal application
    • IO-Link versions – up to eight switchpoints can be programmed
    • Highly compact – can be installed in C- or T-slots
    • Single connector versions in M8 or M12 for two sensors – easily double the sensors on a multi-interface block or sensor distributor

  • Detect Positions on the Locking Cylinder

    With BHS pressure-rated inductive sensors

    Our pressure-rated inductive sensors detect changing positions of the locking cylinder reliably and indicate whether it is locked or unlocked. This increases the reliability of the application and ensures efficiency. By using locking cylinders you can, for example, improve the energy efficiency of the hydraulic drive on injection molding machines. Locking during the injection phase makes high holding pressure unnecessary, in turn allowing the size of the hydraulic drive system to be reduced.

    Features

    • Increase the energy efficiency of machines
    • Small drive system reduces costs
    • With optional diagnostics function – for controlled locking
