se conditions, thanks to its high IP65 protection level. The maximum allowable operating temperature is in the range of –40 °C to +80 °C. The encoder’s permissible maximum shaft loadings are 80 N radial and 60 N axial. The encoder is double-supported. Two precision ball-bearings provide backlash-free support for the encoder. The service life is 109 revolutions at 100% of full rated shaft load and is extended to 1010 revolutions at only 20% bearing load.
