Sensors with fibre optics are used for optoelectronic sensing applications where mounting space is limited or where high operating temperatures do not permit the use of conventional sensors. Due to their small design and optical properties they do not only detect the presence of objects but also quality-related details, e.g. thread pitches of screws.
Transmitter and receiver of the fibre optic sensors are integrated into one housing. The fibre optic is connected to the switching amplifier using a special adapter, and so there is almost no loss. Fibre optics can be used as through-beam sensors or diffuse reflection sensors.
Fibre optics consist of flexible glass fibre bundles protected against external influence by a sheath.
