Through-beam photoelectric sensor FT18SM - CFR

diffuse reflectivecylindricalinfrared

Fiber optic sensors function electronically like any other photoelectric sensor with the difference that the light emitted and received is transported by an optical fiber the end of which is very small and in different forms and it can be installed some distance from the electronic circuit. The reduced dimension of the fiber allows the sensing of very small objects and their installation in areas where other sensors would not fit. Furthermore they can be used in explosion risk areas as well as in liquids and have a very high resistance to mechanical damage and to vibrations which makes them suitable for installation on machinery were movement is involved. They are available in the reflection and barrier emitter/receiver. The light source is red and the length of the standard fibers is 2 metres.
