* Please select when ordering

1) Up to a measuring length of 1020 mm

2) ±5 µm after linear length-error compensation in the subsequent electronics

3) Additional measuring length only on steel mounting surface

4) In the application, the device must be protected from contamination by solids and liquids. If necessary, use a suitable enclosure with a gasket and sealing air.

5) For the electrical connection, look under LIC 411 without functional safety

6) Further tolerances may apply in the subsequent electronics after position value comparison (contact the manufacturer of the subsequent electronics)
