PMIB3-ST POSIMAG
Magnetic Scale
Magnetic scale PMIB3-ST for Position Sensor PMIS3
• Easy splicing
• Resistant to moisture and many fluids
• Extensive ruggedness against dust, chipping etc.
• Magnetic scale with stainless steel base
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
(stainless steel strip CrNi 17 7).
