For the first time ever Turck combines the benefits of magnetostrictive and potentiometric solution with ist new series of linear displacement sensors. The new LI-Q25 series is an interference-free solution for measuring ranges between 100 and 1000 mm. The analog sensors provide a 1 µm resolution (repeat accuracy: 25 µm) and are specially suited for applications that could not otherwise be solved efficiently due to technical restrictions, such as metal-processing machines, rolling mills or injection molding machines.

The IP67-rated sensors Turck will present at the SPS trade show are based on the resonator principle. Unlike magnetostrictive or magnetic inductive position sensors, the LI-Q25 does not require a magnetic positioning device. Instead, the position is detected via a resonant circuit. In this way, splinter accumulations that can affect the sensor’s function are eliminated. Moreover, having a completely sealed housing prevents dirt or dampness from affecting the rugged sensor.

Because of the specially designed coil-system, the output signal is not affected by the distance between the sensor and the positioning device. In this way, measuring errors caused by minor deviations can be prevented – significantly increasing process reliability. Different output configurations (0 to 10 V, 4 to 20 mA, IO-Link, SSI) and optional mounting accessories additionally increase the sensor’s applicability.
