For accurate position measurement of the suspension. Achieving high durability without contact.

In the automotive industry's suspension systems, accurate measurement of stroke length is essential to balance driving performance and ride comfort. To accurately understand the vehicle's movements over road irregularities and curves, high-precision displacement sensors are required for appropriate damping control. Traditional contact-type sensors have risks of malfunction due to wear and foreign material adhesion, but the ET series solves these problems with its non-contact structure. 【Usage Scenarios】 - Measurement of suspension stroke length - Feedback for height adjustment systems - Body posture control during driving 【Benefits of Implementation】 - Improved driving performance through high-precision position measurement - High durability due to non-contact structure - Stable operation in harsh environments
