Turck: Rotary Position Sensor

The QR24 provides contactless position detection.

Aw 20168 1312np Turck

Designed from the company's rotary inductive sensor technology, the unit 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. With no need for contact or bearings, it can execute the same functions as an encoder or potentiometer, while eliminating wear and extending sensor longevity. 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. 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 a multi-core multiprocessor for enhanced speed. The sensor features a fully potted and sealed IP69K/IP67-rated housing to protect against moisture and dust in demanding environments. It also offers flexible parameterization via IO Link or easyteach, allowing the sensor to easily adapt to specific application requirements.
