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.
Fibre optics made of silicate glass are more resistant to heat, ageing and chemicals than acrylic fibre optics. They do not change their optical response when they are bent. Glass fibre optic sensors cannot be cut to length by the user.
High-flex fibre optics allow extremely small bending radii.
