A device for detecting the position of an elevator car (40) by a sensor and evaluation unit (20, 22, 24), accommodated in a sensor housing (10), which can be arranged on the elevator car, is designed for interaction with a strip (14) having a length and/or position coding and which is connected to a switching unit (12) that has a safety switch (30) and/or an interrupter contact for an emergency function, especially an emergency stop of the elevator car, the sensor and evaluation unit being designed for generating a position and/or speed signal from the length or position coding and for generating or receiving an elevator car status signal (62) that corresponds to an opening status of an elevator car. A monitoring device (60) for activating the switching unit is associated with the sensor and evaluation unit and is designed such that the emergency function can be activated as a response to the position or speed signal and to the elevator car status signal if a car movement with the elevator car door open exceeds a predetermined speed threshold value and/or acceleration threshold value and/or displacement threshold value.
