The
incremental encoders are used to convert rotary motion into electrical impulses.
The encoders from Lenord + Bauer combine a magnetic sensing system with a robust mechanical design and have proven themselves worldwide in a broad spectrum of applications in which reliability is essential in harsh industrial environments.
Long service life and negligible maintenance costs are synonymous with these encoders.
Typical applications
 |
Heavy industry |
|
Paper and packaging machines |
|
Bottling plants |
|
Transport and storage systems |
|
Machines for the processing of steel, wood, rock, textiles and plastics |
|
Railway industry |
Measuring principle
The encoders contain a contact-less magnetic sensor system and a precision toothed wheel. The sensor’s magnetic field is modulated by the passing of the teeth of the measuring wheel.
The resulting sinusoidal and co-sinusoidal voltage is evaluated by the integrated electronic and converted to an incremental output and optionally to an additional analogue current output.
Advantages of the magnetic system
|
Unaffected by condensation on the measuring wheel and is therefore the preferred choice for applications, where ambient temperatures change or where the relative humidity is high. (e.g. outdoors) |
|
Unaffected by oil or dirt penetration. |
|
The steel measuring wheel is highly resistant to shock and vibration, unlike glass or plastic graduated discs in other systems. |
|
Excellent reliability over a very long life because it does not suffer from the ageing effect common to optical systems. |
