Magnetic field sensors

Contactless and reliable detection

Magnetic field sensors

Magnetic field sensors are used chiefly on cylinders and grippers for monitoring the piston position. The sensor thus recognizes the field of the magnet integrated into the piston through the actuator wall.

With their contactless position detection, Balluff's magnetic field sensors function reliably and wear free: No contact erosion, no bounce and only clean contact points. Even at high movement speeds, the piston position is reliably recognized.

Magnetic field sensors for T-slot

  • Reliable switching process thanks to precise switching point
  • Contact-free and therefore wear-free
  • Resistant to dirt
  • Especially bright LEDs are visible even from great distances

Magnetic field sensors for C-slot

  • Reliable switching response
  • Precise switching point
  • Contact-free and therefore wear-free
  • Resistant to dirt
  • Low hysteresis

Magnetic field sensors for multiple slot shapes

  • For C- and T-slots with flexible fastening system

Magnetic field sensors for tie rod cylinders

  • Tie rod diameter up to 17 mm
  • Reliable switching process thanks to precise switching point
  • Contact-free and therefore wear-free
  • Resistant to dirt
  • Firm grip
  • Mounts quickly

Single-connector version with two BMF magnetic field sensors

  • Tie rod diameter up to 17 mm
  • Reliable switching process thanks to precise switching point
  • Contact-free and therefore wear-free
  • Resistant to dirt
  • Mounts quickly

Tubular magnetic field sensors

  • Small, extremely compact form factors and very generous switching distances
  • Sensors with a diameter of 6.5 mm can sense position without contact at up to 90 mm
  • Industrial grade and contamination-proof
  • Detect positions even through containers or tubes
  • The detection of codes using magnets is also possible

Magnetic field sensors with adjustable switchpoints

  • Contact-free and therefore wear-free
  • Individual installation of the switching points without tools
  • Applicable for cylinders and grippers with radial or axial magnetic polarization
  • Remote-Teach of up to 8 switching points via IO-Link
  • Adjustable hysteresis for each individual switching point
  • Extremely large, 60 mm travel path
  • Status indication via multiple colored LEDs
  • Captive switching points even after a power outage

Magnetic field sensors for round cylinders

  • Up to 80 mm piston diameter
  • Reliable switching process thanks to precise switching point
  • Contact-free and therefore wear-free
  • Resistant to dirt
  • Firm grip
  • Mounts quickly

Magnetic field sensors for trapezoidal groove and trapezoidal guide

  • Reliable switching response
  • Precise switching point
  • Contact-free and therefore wear-free
  • Resistant to dirt
