From the detection of slim or minute objects, to an advanced series of picking sensors that simplify manual assembly processes, our area sensors are an extremely versatile solution.
Line sensors are designed for accurate measurements of the centre or edge position and width of objects. The detection is made on a reflecting tape, supplied with the sensor, positioned behind the object. They are suitable for a wide range of industrial automation applications, such as packaging, printing assembling on automatic machines.

The colour of an illuminated object depends on all the colour components of the incident light which are reflected, eliminating those which are instead absorbed.

Contrast sensors (also defined colour mark readers, according to the most popular application) present a proximity function but, instead of detecting only the presence or absence of an object, they are able to distinguish two surfaces according to the contrast produced by the different reflection degree.

The luminescence sensors emit ultraviolet (UV) light and receive visible light reflected from luminescent surfaces. This technology allows the detection of fluorescent marks (even invisible to the human eye) on any object independently from its material, colour or distance inside the operating range. Moreover, it avoids light interferences or reflections from non-luminescent surfaces, like glass, mirrors, shiny metal surfaces, etc.
Luminescence sensors can satisfy many different applications, as for example in pharmaceutical and cosmetic industries to detect labels on glass phials or bottles, or correct medicine packaging, in woodworking and ceramic tiles production to check fluorescent selection marks; in automatic packaging to detect whitened paper or fluorescent glues, in textile industry to identify fluorescent cutting guides or labels; in mechanical industry to verify fluorescent paints, lubricants, gaskets or fittings; in vending machines or cash dispensers to check banknotes and credit cards.

A slot sensor is a particular version of the through beam retroreflex sensor, where the emitter and receiver are placed opposite each other on the internal sides of an U-shaped housing. Any target that passes through the internal slot interrupts the beam and is detected.
