A position detector arrangement for an elevator (1) is proposed to comprise multiple flags (21), a flag detection sensor (19) such as e.g. a photo sensor, multiple RFID tags (39) and an RFID detector (43) for reading the identification information stored in the RFID tags (39). Each of the flags (21) is to be attached at a fixed position within an elevator shaft (5). The flag detection sensor is to be attached at a car (3) of the elevator (1). Furthermore, the flag detection sensor (19) is adapted for optically detecting a presence of the flag (21) using e.g. a light barrier arrangement. Each RFID tag (39) stores individual identification information. Furthermore, each of the RFID tags (39) is mechanically attached to one of the flags (21). Reading the individual information stored in the RFID tag (39), the position detector arrangement may provide not only information that the car (3) is located at an arbitrary one of the shaft doors but also information about the identity, i.e. about the location, of the shaft door. Accordingly, e.g. upon power cycling, the elevator may easily determine the position of the car without necessarily performing a lengthy synchronisation run.
