OIS27 Redundant position sensor for hydraulic cylinders OIS27 is a patented smart optical device, which is usually combined with a hydraulic steering cylinder. The main application is on rough terrain machines, to detect when the wheels are correctly aligned. The alignment occurs when the sensor detects a different refraction index zone, which is marked on the hydraulic cylinder’s rod. The product is based on reflective sensor as input stage, a computing unit (microprocessor device) and an output stage with high side driver, which is able to deliver up to 50mA. The sensor includes a lot of “smart” functions and special algorithms that allow to continuously adapt the device to the wear of the system during the time, improve the life of the system, guarantee the high reliability (MTTF = 145 years) and be able to work in the harsh environment (temperature variations, rod wear, presence of electromagnetic disturbs, presence of humidity, shocks and vibrations). Moreover this serie offers, in the same package of OIS21, a fully redundant sensor being able to ensure higher reliability performances.
