Sick has manufactured the W18 photoelectric sensor for the purpose of identifying various targets such as clear PET containers for  Hartness’ GlobalShrink TFS machine. The W18 photoelectric sensor is capable of finding the nature of packing material, from clear bottles to shiny wrappers.

The background suppression feature of the highly-advanced W18 photoelectric sensor does not cause any reflections from the shrink wrap. This resistance helps solve challenges such as slow production time and false trips.

The OES3 technology in the sensor has the capability of avoiding background reflections from the shrink wrap material, thus minimizing false activations on the production line. The background suppression feature of the sensor proves useful for sensing the availability of paperboard trays and containers on the machine.

The Sick UM18 ultrasonic sensor delivers high-precision measurement even on translucent items. The sensor has been used for measuring film diameter for Hartness’ GlobalShrink TFS system.

Hartness selected the KT5 contrast sensor because it can be used to detect film registration. With a host of advanced features such as automatic selection of 3-color LED lights, teach-in alternatives, advanced optics, and built-in bar graph display, the KT5 contrast sensor proves useful in fixing and studying parameters with ease in the field.
