LC 181 by HEIDENHAIN
Sealed Absolute Linear Encoders

Absolute linear encoders provide the absolute position value immediately upon switch-onŚwithout previous movement of the machine axes. The absolute value is transmitted serially to the subsequent electronics over the EnDat interface.
Measuring standard - DIADUR glass scale with 7 tracks of differing grating periods
Data interface - EnDat (synchronous serial)
Incremental Output signals - 1 VPP, signal period 16 Ám
Accuracy grade ▒ 5 Ám , ▒ 3 um
Recommended measurement steps 1 Ám to 0.1 Ám
Measuring lengths 240mm to 3040mm
The LC 181 absolute linear encoder generates the absolute value from seven incremental tracks. The grating periods of the tracks differ in a manner that makes it possible to evaluate the measuring signals of all seven tracks to identify any location on the scale within the measuring length.
Using the finest track, with a grating period of 16 Ám, the LC 181 can produce an absolute value to a resolution of 0.1 Ám and finer over a measuring length of 3 meters.
The absolute value is transmitted serially to the subsequent electronics over the EnDat interface.
In addition to the absolute position information, the LC 181 provides sinusoidal incremental signals with a signal period of 16 Ám and levels of 1 VPP
IMPORTANT: The new LC 183 is NOT always a direct replacement. Please call us with the ID# off your older LC 181 and we will find a solution for you.
