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 dis-

tances and works as a solid measure. Reference marks can

be user defined in 4 mm resp. 10 mm steps. The magne-

tic scale retains its firmness by means of a spring steel base

(standard steel strip CK 85).
