The attachment of colour marks that are then evaluated with a colour or contrast sensor is a proven method for identifying objects in industrial production. Even objects with differing shapes and surface properties can be very reliably detected in this way.

FT 25/50 C

The FT 50 C can not only differentiate between individual colours, but also user-defined colour ranges. Thanks to its high level of colour selectivity, this sensor is suitable for almost all industrial colour detection tasks.

FT 25-W/-RGB

The F 25 series also includes contrast sensors which, with their small and precise light spot, can differentiate between the slightest of contrast differences on objects or printed marks at high process speeds. The FT 25-RGB, with its multi-colour RGB evaluation, can even automatically select the ideal transmission colour (red, green or blue) for the contrast that is present. The FT 25-RGB is well suited for the detection of one colour in fast processes.

FT 50 C-UV

Finally, the FT 50 C-UV luminescence sensor is a special product: this innovative sensor detects features that are invisible to the human eye by irradiating the target object with ultraviolet light. This sensor has a highly varied range of applications because luminophores are not only attached to labels, but can also be mixed with different materials (e.g. paint, chalk, glue and lubricants).

• Precise detection of the finest colour or grey value diferences and non-colours
• Detection of self-illuminating colours and luminophores
• Numerous outputs and interfaces for simple integration in machine control systems
• Comfortable operation by means of teach-in or configuration software
• Maximum positioning accuracy, even at high process speeds
• Automatic transmission LED colour selection; communication via light spot – simple, comprehensible, clearly defined
