Measuring > Linear Encoders > Magnetic Rings
Useful with incremental ELGO sensors
 
Functions
Direct assembly on axes possible (e. g. motor shaft)
Contactless and wear free measurement principle
Applicable in roughest environments (protection class IP67)
Vibration- and shock-resistant
Pole division 5 mm (for LMIX and GMIX systems) or 2 mm (EMIX systems)
Three different sizes (small, medium and big)
Features
All advantages of the magnetic measurement principle are available by using magnetic rings for rotary movements e.g. revolutions -, angle or extent measurements also. Besides the magnet rings are a wear-free and space-saving alternative to optical rotary
