Description
The HEIDENHAIN LIF 121 utilized a phase grating on glass with a grating period of 8µm, manufactured in the DIADUR process, serves as a measuring standard for this LIF incremental linear encoder with TTL output. The scales of LIF linear encoders are fixed with HEIDENHAIN PRECIMET® elastic adhesive film directly onto the mounting surface. This adhesive film ensures a defined thermal behavior and is resistant to solvents. The mounting procedure is quite fast thanks to its simplicity and to relatively large mounting tolerances.
