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

The Limes LI50 / B2 contactless incremental magnetic length measuring system - consisting of the LI50 sensor head and the B2 magnetic strip - allows a resolution of up to 5 μm with a maximum distance of 2 mm between sensor and strip.

For outdoor use, with a particularly sturdy aluminum housing and stainless steel cover, wide temperature range, and UV-resistant cable. Protection type IP68 / IP69k, special
encapsulation technology, and tested resistance to cyclic humidity and heat provide maximum reliability even in unprotected outdoor use.
