The multi-colour touch sensors from ifm allow flexible adaptation to your application. Where many different sensors were required before, one individually adjustable sensor is sufficient today. The NO/NC function or the colours for different operating states can be set within seconds. In addition, dynamic, static or bistable switching of the sensor can be selected. The adjustable sensitivity allows use in very wet environments or actuation with gloves. The implemented delay time prevents unintentional switching of a sensor. All settings remain stored even if the sensor is used without IO-Link. The sensor also counts the switching cycles for demand-oriented maintenance of the machine.
