Bearingless
zero pulse, magnetic RI50 / Limes LI50 (hollow shaft) Push-Pull / RS422

Thanks to its installation depth of only 16 mm, the bearingless magnetic rotary
encoder RI50 / Limes LI50, comprising a magnetic ring and sensor head, is ideally
suited for plants and machinery where space is very tight. The non-contact
measuring principle allows for error-free use even under harsh environmental
conditions, as well as ensuring a long service life. In contrast to our measuring
system RI20 / Limes LI20, a single zero pulse is also implemented here.
For outdoor use with extremely sturdy aluminium housing and stainless steel
cover, wide temperature range as well as a UV-resistant cable. IP68 / IP69k
protection, special encapsulation technology and tested resistance to cyclic
humidity and damp heat offer the highest levels of reliability, even in exposed
RoHS
outdoor use.
