Rotary Position Sensor Provides Contactless Position Detection.

TURCK introduced the new QR24 rotary position sensor. Based on the company’s rotary inductive sensor technology, the QR24 provides contactless position detection and wear-free performance in a variety of industrial applications ranging from solar energy plants and harvesters to crane vehicles and AGVs, the company says.

“Today’s rotary encoder applications are becoming more demanding,” said Marty Cwach, product manager, TURCK. “More and more applications require a higher degree of ingress protection, smaller package size and longer life expectancy. TURCK’s new QR24 incorporates these new requirements and meets or exceeds the demands.”

The TURCK QR24 is part of the company’s Q-track family of sensors, which utilize resistance inductive capacitance (RLC) measuring technology. Unlike potentiometric or magnetic technologies, the sensors incorporate 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.

According to the company, the multi-coil system provides high resolution, while ensuring 16-bit noiseless operation. The sensor also features a double resonator system, providing increased distance capability and high-end signal processing with multi-core multiprocessor for enhanced speed.
