Magnetic length measuring system, incremental – suitable for the harshest environments.

The non-contact incremental magnetic linear measurement system Limes LI20 / B1 - made up of the sensor head LI20 and of the magnetic band B1 - reaches a resolution up to 10 μm with a maximum distance of 1 mm between the sensor and the band.
For outdoor use with extremely sturdy aluminium housing and stainless-steel cover, wide temperature range as well as a UVresistant cable. IP68 / IP69k protection, special encap-sulation technology and tested resistance to cyclic humidity and damp heat offer the highest levels of reliability, even in exposed outdoor use.
