Estimating the term…
Position transmitting equipment for ascertaining the position of a rail-guided elevator car includes a code carrier, which is arranged over the car travel path in fixed location on a guide rail with code marks of different permeability. A permanently precise reading of the coding is ensured by the fact that the code carrier is fixedly connected with a non-magnetic cover externally covering the code marks. The code carrier together with the outwardly facing non-magnetic cover are inserted into a receiving groove of the car guide rail, whereby a simple and reliable mounting is achieved and, in addition, temperature-dependent differences in expansion between the code carrier and the guide rail are avoided.
