Magnetic field sensor MB-F32-A2
Magnetic System
Primary Construction of the Magnetic System
Non-magnetizable
sealing ring
and sliding ring
package
Cylinder wall (steel)
magetically soft
Lines of
magnetic flux
Non-magnetizable
material
For this sensor principle it is not sufficient to simply
mount the permanent magnet onto the piston. A
magnetic system has to be constructed which conducts
the magnetic flux of the permanent magnets directlt into
the cylinder wall in order to achieve the strongest possible
magnetization. For further details regarding the construction
of magnetic systems, refer to the manual. A field trial is
generally recommended before practical operation!
Magnets
The magnets are axially magnetized. It must be
ensured that all magnets are mounted with the same
polarity!
Definition of polarity
An approaching permanent
magnet with the north pole
pointing towards the cable
connection of the sensor causes
output 1 to respond and the red
LED to light.
Antivalient output
By means of the sensor’s antivalent output stage the
appropriate output can be chosen depending on the
polarity of the magnetic system or the mounting location of
the sensor
Mounting
The sensor is mounted directly on the surface towards
the cylinder axis. For this purpose, pressure bands,
tightening straps, or hose band clamps can be used.
