A method can be used for operating an optoelectronic proximity sensor. The proximity sensor includes a radiation-emitting component, a radiation-detecting component and a control unit. The radiation-emitting component is operated by means of a pulsed current. During each measurement period, the pulsed current of the radiation-emitting component has an on-time and an off-time. The pulsed current has a pulse current intensity during the on-time, and the control unit evaluates a detector signal of the radiation-detecting component and lowers the pulse current intensity for a subsequent measurement period, when the detector signal exceeds a threshold value during at least one measurement period. |
