Abstract
An optoelectronic device for sensing an object without any contact, the optoelectronic device being adapted to be connected to a control device which is capable of sending an identification code to the optoelectronic device, the optoelectronic device includes an optoelectronic element (110, 111) for receiving an input signal and for converting the received signal into an electrical signal, an address memory (121) for storing a self identification code, a determining unit (126) connected to the address memory (121) for determining a coincidence between the self identification code stored in the address memory (121) and the identification code sent from the control device, and an activating unit (127) connected to the determining unit (126) for driving the optoelectronic element (110, 111) at a time when the self identification code coincides with the identification code.
