Abstract
A sensor apparatus comprising a distance sensor comprising a transmitting device having at least one transmitter with a light source, and a receiving device having at least one receiver, and an electronic unit. The electronic unit being designed to emit light by means of the transmitter and to determine a distance which is covered by light emitted by the transmitter from a reflection surface of an object in a monitored area to the respective receiver. According to the invention, light guide means for transmission of light are arranged between the transmitting device and the monitored area and/or between the monitored area and the receiving device. The light guide means reflects the light at least once so that light can pass from the transmitting device to the monitored area and/or from the monitored area to the receiving device on an angled path.
