F 25: For every application the right sensor

Color sensors work according to the principle of energetic reflection, in which the partial spectra of red, green and blue are evaluated separately. The three colors are transmitted one after the other and the amount of light that is reflected by the target object is registered individually at the FT 25-C sensor.

Contrast sensors

Contrast sensors work according to the principle of energetic reflection and detect gray scale differences on matt, glossy or transparent objects and surfaces. The F 25-series photocells are convincing not only by the wide range of variations, but also by many useful details that make the difference in an application. All F 25 sensors from SensoPart are available as laser and LED versions.

The FT 25-W contrast sensor uses white light and has a very small and accurate rectangular light spot (1 x 4 mm²). This also makes it possible to detect very small printed markings and colored objects with weak contrast differences. The sensor can be parameterized during running machines and during the teach-in process, the switching threshold automatically adjusts to the object, color and background.

High switching frequency 25 kHz

Due to the high switching frequency (25 kHz) of the FT 25-W and FT 25-RGB contrast sensors, the front edges of printed markings are very precisely detected and achieve maximum positional accuracy. This also ensures reliable sensor switching behavior, even at very high processing speeds. The FT 25-RGB contrast sensor has three different transmissions LEDs (red, green and blue). During teach-in, the sensor evaluates the taught-in contrast and then automatically selects the ideal transmission color (red, green or blue) for the contrast present. As a result, even extremely low contrast differences can be reliably detected.
