PMIB3 POSIMAG®
Magnetic Scale
Magnetic scale PMIB3 for Position Sensor PMIS3
• Easy splicing
• Resistant to moisture and many fluids
• Extensive ruggedness against dust etc.
The magnetic material is magnetised in defined and even distances and works as a solid measure. Reference marks can
be user defined in 4 mm resp. 10 mm steps. The magnetic scale retains its firmness by means of a spring steel base
(standard steel strip CK 85).
