Shaft copy system – safe and absolute positioning of the elevator car.

Absolute position acquisition, SIL3. Ants LES01 is an extremely robust, compact measuring system. With a resolution of 1 mm and a travel speed of 5 m/s, absolute position values of the car are determined slip-free using a contactless measuring principle. No additional components such as magnetic switches are necessary. Simple assembly especially reduces installation times and thus contributes to the reduction of the overall costs.
