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

bullet

Heavy industry

bullet

Paper and packaging machines

Bottling plants

bullet

Transport and storage systems

bullet

Machines for the processing of steel, wood, rock, textiles and plastics

bullet

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

 

bullet

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)

bullet

Unaffected by oil or dirt penetration.

bullet

The steel measuring wheel is highly resistant to shock and vibration, unlike glass or plastic graduated discs in other systems.

bullet

Excellent reliability over a very long life because it does not suffer from the ageing effect common to optical systems.
