Datasheets

Magnetic field sensors detect a permanent magnet or magnetic actuator through non-magnetisable materials such as stainless steel, aluminium, plastic or wood. They provide very long sensing ranges from small housings and are used for piston position in cylinders, valves, doors and lids and for detection through tank or guard walls.

Key features

  • Sensing ranges from 2.5 to 80 mm depending on the magnet
  • Cylindrical Ø 8, 12, 18 mm and rectangular housings, including Hall effect sensors
  • PNP, NPN, PNP/NPN and NAMUR outputs
  • ATEX/IECEx-certified NAMUR versions for hazardous areas
  • Permanent magnets and magnetic actuators available as accessories
