Optical sensors are particularly advantageous for measurements over a long distance. In addition, straight pushbuttons are very easy to install and save space. Barriers have long ranges and are not very susceptible to interference. Laser reveals its advantages when it comes to high range and small objects. In summary, the following advantages can be noted:
Little susceptible to interference
Good detection of small objects
These advantages do not apply to all optical sensors at the same time. Depending on the application, an individual decision must be made as to which optical sensor is best suited.
