Technical Data
6.5. position Measuring system data
Stroke range (measuring range): 0 ... 80 mm
Resolution: ≤ 0.1 mm
Total fault: ± 0.5 mm - when using a target in accordance with the dimensional drawing,
Material 1.4021 and a piston rod (Ø 22 mm, Material - see (*))
(Fault refers to the reproducibility of a taught position)
The illustration in Fig. 5 shows the dimensional relationships between the control head and the piston with a target.
Target (1.4021)
and
Piston rod (*)
(both depicted in the upper
and lower end positions,
maximum stroke: 80 mm)
Note upper end position of
the target (H 156.5 mm) to prevent
putting control head at risk!
Fig. 5: Cross-section of the control head and piston with target (in upper and lower end position)
(*) The fastening materials for target and piston rod may not be made of material with very good electrical
conductivity (e.g. copper, aluminum) or of ferromagnetic material.
Stainless steels such as e.g. 1.4404 are suitable.
