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
