What is a fibre optic sensor?

A fibre optic sensor is a type of photoelectric sensor that enables detection of objects in narrow locations. Due to their compact design, they can be positioned in key workplace locations.


Fibre sensors operate on the principle that an object interrupts or reflects light, so they are not limited (like proximity sensors) to only detecting metal objects. Fibre sensors can be used to detect virtually any object including glass, plastic, wood and liquid.


Benefits of OMRON’s fibre optic sensing technology

OMRON’s fibre sensors feature a small, compact sensing section and flexible fibre unit cable, enabling them to squeeze into small areas.


The requirements for fibre optic solutions can be very demanding particularly for applications with extreme temperatures and for applications requiring the reliable detection of a wide range of objects with different materials, shapes or colours.


The sensing section of a fibre unit has no electric circuits, making it highly reliable even under severe environmental conditions, such as temperature, vibration, shock, water and electrical noise.
