Magnetic cylinder sensors

Detecting piston positions with precision

In countless fields of automation, it is essential to monitor the motion processes in pneumatic cylinders. Magnetic cylinder sensors contactlessly detect the piston position of these cylinders and give a switching signal. They are completely maintenance-free and are mounted outside the cylinder.

With cylinders with standard T or C slots, the sensors can be pushed directly into the slot and secured. With all other cylinders, the sensors are quickly and easily mounted using components from the wide range of accessories. Our magnetic sensors can be fixed to all commercially available cylinders, thus offering you maximum flexibility.

Of course Baumer can also offer you assembly kits with various fixing clamps and brackets.

  • Areas of application
    • Cylinders with C- and T-slot

      • Eased installation – simply inserted in the slot
      • The permanent magnet inside the cylinder is detected through the cylinder wall
      • Completely free from maintenance and wear

      Attachment to cylinders without slot

      Versatile mounting accessory kits allow attachment to any conventional cylinder:

      • Round cylinders
      • Tie-rod cylinders
      • Dovetail or other specialised slots

      Compact sensor designs for short-stroke cylinders

      By virtue of its lateral cable outlet, the sensor is very short and easy to fit into tight spots

    General information


    Magnetic cylinder sensors are deployed to register the positions of pistons in pneumatic cylinders. They detect the piston-carried permanent magnet through the cylinder wall utilizing the magnetoresistive principle.
