EXPOSED LINEAR SCALES

LIDA
LIDA incremental linear encoders use AURODUR steel scales with grating periods of 20  Ám (LIDA 400) or 40 Ám (LIDA 100) as measuring standard. The new LIDA models are relatively insensitive to scale contamination and unevenness of the mounting surface.

LIDA 400
  • Measuring lengths up to 30 m
  • High traversing speed
  • For limited installation space
  • Signal period 20 Ám

LIDA 171, LIDA 181

Heidenhain Exposed Linear Scale

LIDA 171:  TTL 
LIDA 181:
  1 VPP
The AURODUR steel scale tape of the LIDA 171/LIDA 181 is cemented into a steel scale carrier and then calibrated. A calibration chart is supplied with every scale.

 

LIDA 175, LIDA 185

Heidenhain Exposed Linear Scale
LIDA 175:  TTL 
LIDA 185:
  1 VPP
The LIDA 175/LIDA 185 is intended for larger measuring lengths up to 30 m (100 ft). Here the one-piece AURODUR steel scale tape is inserted into a scale housing consisting of several standard sections; it is then stretched to a defined tension and fixed at both ends to the machine bed.

 

LIDA 177, LIDA 187

Heidenhain Exposed Linear Scale
LIDA 177:  TTL 
LIDA 187:
  1 VPP
The LIDA 177/LIDA 187 also consists of a one-piece steel tape. In this case, however, it is guided in a scale-tape carrier and is rigidly connected at its center to the machine. Measuring lengths up to 6 m (237 in.) are available.
