Encoder lineari assoluti di alta gamma – Serie L3B

L3B series

Linear encoder with small reader head, air purge and connector at both ends, with threaded head for different mounting options without the need for nuts.

Its special mechanical extrusion design, protective lips and securing points  on the linear encoder, the high quality optical components and powerful  FPGA-based electronics using advanced embedded algorithms allow for the reduction of errors to ensure the accuracy and repeatability of linear  encoders. From 4 meters onwards the module ends machining design together with an outstanding rubber seal allow for an easy installation and ensure the protection against liquids in the joints.

This results in linear encoders especially suited for hostile work environments in settings requiring high speed and vibration standards.


Measuring lengths in millimeters

Available in measuring lengths from 440 mm to 50 m in 200 mm increments. Contact Fagor Automation for custom solutions if your application requires longer lengths.
