Fibre optic systems are used where mounting space for photoelectric standard sensors is restricted. The evaluation unit and the fibre optics are mounted separately.
These systems can therefore be installed in places where access is difficult.
Fibre optic systems are designed as through-beam or diffuse reflection sensors.
Acrylic fibre optic sensors are suited for standard applications if no particular demands such as heat or chemical resistance are made. They can be cut to length and are less expensive than glass fibre optic sensors.
