TECHNOLOGY ADVANTAGES
The coaxial optics is present also in the polarised retroreflex model for the detection of transparent objects, notably increasing the per-
formances of this optic function and its immunity to object movements inside the detection area.
The contrast sensor with white LED emission has an operating distance ranging from 17 to 21 mm and detects coloured or grey-scale
marks, with a minimum dimension of 0.5 mm and an operating frequency reaching 5 kHz.
The luminescence sensor with UV LED emission has an operating distance ranging from 0 to 40 mm and detects fluorescent or lumi-
nescent targets, with a minimum dimension of 0.5 mm and an operating frequency reaching 2 kHz.
The setting of these sensors is extremely rapid and easy, thanks to the patent-covered EASYtouch™ system that alllows to automati-
cally fix the object detection threshold, with a single pressure of the teach-in push-button.
It is possibile to set the sensor to detect more critical differences between the mark and the background, or invert the dark or light ope-
rating mode, by pressing twice the push-button.
The EASYtouch™ system allows to select the ‘Remote’ function for the remote sensor setting through the cable or connector, the
‘Keylock’ function to block the keyboard, ‘Delay OFF’ function for the 20 ms timing of the output deactivation.
The sensor technology with background and/or foreground suppression of the S60 series has allowed to develop also a cost-effective
distance sensor with a double output: a 0 - 10 V analogue output and a digital NPN or PNP switching output.
The measurement range and the switching threshold output can be selected in the 50 - 150 mm range, with a ± 1 mm precision; the
direct or inverse proportionality and the light or dark operating mode can be selected.
