Fibres, fibre optic sensors and light strips

Fiber optic sensors - Fibers - Light strips - SensoPart

SensoPart light strips (fibres) are the solution for applications where there is too little installation space for a photocell, a high temperature or a lot of pollution. Robust fibre jackets also provide excellent protection against harsh chemicals. The amplifiers are placed in a switch box or at a safe distance, while the fibre head can be placed close to the object to be detected. Depending on the application, fibres are available as transmitter-receiver or as diffuse sensors. The powerful glass fibre sensors ensure a high degree of functionality and reliability.

Advantages of fibres or light strips:

  • High flexibility and low weight on a robot gripper
  • Resistant to aggressive chemicals in the pharmaceutical or food industry
  • Detection of red-hot objects
  • Minimum spot diameter for the detection of small objects
  • Detection of liquids and levels in supply hoses

Multiple detections on one object

Fibres are often used in applications where multiple detections have to take place on one object. Interference from different sensors can be a problem. The current generation of fibre sensors has the possibility to synchronize in a way that makes the detection reliable and the different fibres do not influence each other.

Light guidance is based on the physical effect of total reflection, whereby light is repeatedly reflected through the inner wall of the fibre back into the glass fibre. The main advantage of this technology is that the light can be transported over long distances with almost no loss. The fibres can have a core of plastic or glass. Glass fibres are highly resistant to chemicals and high temperatures.
