Abstract

An optical transmitting and receiving device with light-conducting receiver, which are arranged inside the housing, in front of a light-permeable cover between a transmitting unit and a receiving unit, so that the share of light reflected at the light-permeable cover of the transmitting unit is conducted to the receiving unit, thus making it possible to detect the operational readiness of the transmitting unit as well as the degree of soiling of the light-permeable cover.
