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.
