Heidenhain Exposed Linear Scale

LIF 101:  11 APP
LIF 121:  TTL 
LIF 181:  1 VPP
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.
