In order to determine the position of a rail-guided elevator car, the position transmitter device has a code support (9), which is mounted in a fixed manner on the guide rail (7) over the guideway and which is provided with code marks each having a different permeability. A constantly exact reading of the coding is ensured by virtue of the fact that the code support (9) is joined to a non- magnetic covering (15) in a fixed manner, whereby the code marks are covered toward the exterior by the non-magnetic covering (15). In an advantageous design, the code support (9) is inserted with the outwardly pointing nonmagnetic covering (15) into an accommodating slot (16) of the elevator car guide rail (7), whereby achieving a simple and reliable fitting and, in addition, preventing temperature-dependent expansion differences between the code support and the guide rail.
L'invention vise à déterminer la position d'une cabine d'ascenseur sur rails. A cet effet, le dispositif de détection de position comporte un porteur de code (9) présentant des marques de code de perméabilités différentes, disposé sur le rail de guidage de manière fixe sur le trajet de ladite cabine. Une lecture précise et durable des codes est mise en oeuvre par liaison fixe du porteur de code (9) à un capot amagnétique (15), les marques de code étant recouvertes vers l'extérieur au moyen d'un capot amagnétique (15). Dans un mode de réalisation avantageux, le porteur de code (9) est logé dans une rainure de réception (16) du rail de guidage de cabine (7) avec le capot amagnétique (15) dirigé vers l'extérieur. Ainsi, il est possible de mettre en oeuvre une construction simple et fiable et d'éviter par ailleurs des écarts de dilatation dépendant de la température entre le porteur de code et le rail de guidage.
