Encoder lineari assoluti di alta gamma – Serie G3B

Linear encoder with small reader head, air purge and connectorat 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.

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