Heidenhain: Absolute angle encoders without integral bearing (ECA 4000 Series)

Measuring angles with angle encoders

HEIDENHAIN angle encoders are characterized by high accuracy values in the arc second range and better.

Examples for application:

Rotary tables on machine tools
Swivel heads on machine tools
C axes on lathes
Gear-testing machines
Printing units of printing machines
Spectrometers
Telescopes

Angle encoders without integral bearing

The angle encoders without integral bearing (modular angle encoders) are intended for integration in machine elements or apparatuses. They are suited for the following requirements:

Large hollow shaft diameter (up to 10 m with a scale tape)
High shaft speeds up to 40000 rpm
No additional starting torque from shaft seals
Segment solutions

Angle encoders with graduation on steel scale drum | Field of application

Rotary tables, Swivel heads, Accurate, highly dynamic motors
Large diameter range
High permissible shaft speeds
High accuracy
Various shapes of drum
Various line counts per diameter
Protective cover for increased resistance to contamination
