Magnetic Strip
®
Compact Sensor for Industrial Applications
Magnetic Strip PMIB2
· Easy splicing
· Resistant to moisture and many fluids
· Extensive ruggedness against dust, chipping etc.
The magnetic material is magnetised in defined and even distances
and works as a solid measure. The defined magnetisation represents
the sensor track and the magnetic strip also contains two additional
reference marks. The magnetic strip retains its firmness by means of a
spring steel base.

An unmagnetic masking tape made
of stainless steel is available as an
accessory (see page 71).
Note: For correct application the
magnetic strip must be longer than
the measuring distance by at least
25 mm at each end of the strip.
The magnetic strip is flexible and can
be glued to the surface of a cylinder
with a minimum radius of 100 mm
and used for angular measurement.
