Rotary feedback is critical in nearly every installation, and most rely on their mechanical bearings to provide proper tolerance and position of the internal system. After time, this results in mechanical wear, vibrations, potential leaks and requires spring elements. The QR24 provides superior performance without the need for contact or bearings, allowing it to successfully execute the same functions as an encoder or potentiometer, while eliminating wear and extending sensor longevity.
The TURCK QR24 is part of the company’s industry-recognized Q-track family of sensors, which utilize resistance inductive capacitance (RLC) measuring technology. Unlike potentiometric or magnetic technologies, the sensors incorporate precisely manufactured printed emitter and receiver coil systems. The emitter coils are activated with a high frequency AC field and produce an inductive RLC circuit with the positioning element. The element is inductively coupled with the receiver coils, which are arranged so different voltages are induced in the coils, depending on the position of the actuator. The voltages serve as a measure for the sensor signal.
