Positioning of Elevators with WCS Position Encoding System [Movie]
The absolute position of the elevator car is transmitted to the elevator control at an accuracy ± 0.4 mm, independent of the load and temperature variations. The contact-free WCS position encoding system enables precise floor/cab zone positioning without the mechanical wear, linkages, and slippage associated with traditional absolute encoders.
