    magnetic incremental encoder with current output

The magnetic incremental rotary encoders GEL 293 are based on contactless magnetic scanning of an integrated ferromagnetic precision target wheel. The resilient housing with a flange size of 115 mm is available with radial connector or cable outlet. The integrated flexible hollow shaft coupling of the encoder is mounted on the drive shaft with a diameter of 16 mm.

Optional designs include a condensate outlet or additional protection measures against moisture and vibration for harsh environmental conditions.

Applications
  • Heavy industry
  • Paper and packaging machines
  • Bottling plants
  • Transport and storage systems
  • Linear measuring eg. belt-drive 
  • Machines for the processing of steel, wood, rock, textiles and plastics
  • Offshore and marine applications
Advantages of the magnetic system
  • Absolute operational reliability even in case of high humidity (dewing) and frequent change of ambient temperature
  • Withstands extreme impacts and vibration
  • Resistant to dirt, humidity and oil
  • No ageing of the magnetic sensor technology
