| The ERO
1400 series are miniaturized modular rotary
encoders for drive shafts up to 8 mm. The ERO 1421 and ERO 1481 feature a special integral mounting aid which centers the graduated disk to the scanning unit and sets the gap between the graduated disk and the scanning reticle. The encoders of the ERO 1400 series are supplied with a cover cap for protection against extraneous light, contamination and electromagnetic fields. |
