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 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).

Model name
Magnetic period
20 = 2 mm / 50 = 5 mm
Mounting of the magnetic scale
N = adhesive taping
Measurement range (total length = range + X mm, refer to the table on page 12
)
e.g. 100, 500, 1000 ... 2500 mm (up to 50 m on request)
Measurement ranges must be divisible by 4 (resp. by 10)
Reference marks/end position marks (optional)
R1 = reference mark on the left / R2 = on the right
E1 = end position mark on the left / E2 = on the right
Additional reference marks every 4 mm (period 2 mm) resp. 10 mm (period 5 mm) from the left
Options
FP = magnetic scale in flat profile
HP = magnetic scale in high profile
AB = Masking tape (only with FP or HP)
Order example: PMIB3 - 50 - N - 1500 - R1
