The incremental rotary angle encoders without integral bearing operate without friction. 

The two components, the scanning head and the scale disk, drum, or tape - are adjusted to each other during assembly.

In addition to the system accuracy, the mounting and adjustment of the scanning head normally have a significant effect on the accuracy that can be achieved with rotary encoders without integral bearings. Of particular importance are the mounting eccentricity and radial runout of the measured shaft.   

The inductive rotary encoders of Z48 series are mechanically compatible with the photoelectric encoders K48 series: the shaft is fastened with a central screw. 

The stator of the encoder is clamped by an axially tightened screw in the location hole. The photoelectric ERO modular rotary encoders from our hengxinag factory consists of a graduated disk with hub and a scanning unit. 

They are particularly well suited for limited installation space or for applications for which there must be no friction.
