Magnetic encoder offers new interface options

Motor Technology product story

The GEL 235 encoder is designed with a steel code disc from which readings are applied to a Vernier scale to give an accuracy of 0.1 degree.
Lenord + Bauer's GEL 235 high-resolution magnetic encoder is now available in the UK from Motor Technolog,y with new interface and fieldbus options, CANopen, Profibus and the serial BISS interface.
This will enable the encoder to be integrated into drive networks on machinery and mechanical handling systems.
The encoder is designed with a steel code disc from which readings are applied to a Vernier scale to give an accuracy of 0.1 degree.
Magnetic encoders have not previously been capable of achieving this level of accuracy and so despite their rugged construction they have not been suitable for aggressive environments where high accuracy was required.
The main benefit of the GEL 235 is that it can be used in applications where there is a lot of vibration, heat or moisture that would otherwise cause problems for an optical encoder.
Designers and end users can therefore benefit from the robust characteristics of a magnetic encoder with the accuracy of an optical unit.
Applications so far have included blast furnaces, rail vehicles, high-speed motors, wind turbines and production lines.
To ease the replacement of existing optical encoders the GEL 235 is available in a number of industry standard formats and has a construction length of only 47mm.
