Classification of grating ruler:
The enclosed grating ruler can effectively prevent dust, chip and splash
It is an ideal choice for machine tools

There is no mechanical contact between the open grating ruler and the reading head and the grating ruler or steel strip
Typical applications of these grating rulers include measuring machines, comparators and other precision length measuring equipment, as well as production and measuring equipment, such as in the semiconductor industry

The incremental grating ruler determines the current position by counting the steps from the origin or the number of counting signals of the subdivision circuit
Heidenhain's incremental grating ruler has a reference point
When starting up, the reference point must be reset
The operation is very simple and fast

The type grating ruler can directly provide the current position value without performing the reference point zeroing operation
The position value of the grating ruler is transmitted through the EnDat interface or other serial interfaces

 
The enclosed linear grating ruler of Heidenhain company can effectively prevent dust, chip and splash
It is an ideal choice for machine tools

Accuracy class ± 2 & mu; m
Measure step to   0,001 & mu; m
Measuring length to 30 m
Easy and fast installation
Large installation tolerance

Strong anti pollution ability
Enclosed linear grating ruler
 
Standard grating ruler housing
– For applications with strong vibration
– Measuring length 30 m
Compact grating ruler housing
– For applications with limited installation space
– The measuring length is 1240 mm
If mounting plate or fastener is used, the measuring length is 2040 mm
The aluminum shell of Heidenhain closed linear grating ruler effectively protects the grating ruler, reading head and guide rail from dust, chips and cutting fluid
The elastic sealing strip with automatic downward pressure keeps the housing sealed

 
The reading head moves along the small friction guide rail of the grating ruler
The reading head is connected with the external mounting frame through a coupling, which can compensate the inevitable alignment error between the grating ruler and the machine tool guide rail
