Turck has developed a completely contactless rotary encoder that outputs its measured value via IO-Link. According to the manufacturer, this makes the QR24-IOL a cost-effective alternative to encoders with an analog interface. Users connect the singleturn encoder via a standard M12x1 connector and save on expensive shielded cables by using simple three-wire cables. The zero point of the encoder is freely selectable - it is simply parameterized via IO-Link after installation. This means that it is no longer necessary to optimally align encoders with their electrical connection and work with correction factors for the zero point in the control system. The measuring range, resolution and orientation of the signal (CW/CCW) are also freely adjustable via IO-Link. The absolute resolution is 0.005°. The data storage function of IO-Link 1.1 enables plug & play replacement of the encoder in the event of defects. All relevant parameters of the encoder can be stored in the IO-Link master and are automatically applied to every encoder of the same type.
