Robust and Resistant to Cleaning – Smart Sensors in Stainless Steel 316L

Photoelectronic sensors in 2K format belong to the intelligent PNG//smart product series. Thanks to their robust stainless steel 316L housing, they can withstand intensive high-pressure cleaning up to 100 bar at temperatures up to 80 °C, aggressive cleaning agents, coolants and lubricants, as well as mechanical influences and corrosion. They are able to measure distances, detect objects and communicate intelligently via IO-Link. The miniature design, which can be easily integrated into any system, is available to users in six functional principles and three light sources.

The 2K Format in Use – Robust Exterior, Intelligent Interior

Detection of Biscuit Cookies

In the production of cookies, the objects must be transported and gripped between different processes on multi-lane conveyor belts. After baking in the oven, they are individually conveyed on rails and prepared for the packaging process. They must be counted before gripping and moving. For this purpose, a reflex sensor with background suppression is installed above each lane on the conveyor line, which detects the cookies from the front edge. Thanks to the stainless steel 316L housing, the sensors are ideal for hygienically demanding cleaning at high temperatures.

Position Sensing of Material on Lathes

In CNC lathes, raw material is fixed in clamping devices. Before the machining process begins, it must therefore be ensured that the workpiece is in the correct position. If it is clamped incorrectly, has slipped or is not present, the machining process does not start. For this purpose, a reflex sensor with background suppression is installed on the side of the machining center, which detects the workpiece precisely with laser light. The robust stainless steel 316L housing (IP69K degree of protection) is resistant to aggressive coolants, lubricants or metal shavings.

Position Check of Loading Carts

Machines that can handle large quantities at once are used to crush and mix food in industrial production. When the mixing process is complete, the mixing trough tilts forward and empties the contents into one or more loading carts. Its exact position below the ejection point is detected by energetic reflex sensors in the ECOLAB-certified stainless steel housing and IP69K degree of protection. This is the only way to ensure that the contents are fully emptied into the containers without any spillage.

Leading Edge Detection of Soft Cheese

In the production of soft cheese, the wedge-shaped pieces of cheese are transported to the packing station on conveyor belts. In order to trigger the packaging process on a special bagging machine, to monitor the distance between the objects and to prevent jamming, the front edges of the cheese pieces must be reliably detected. For this purpose, a through-beam sensor is installed on the side in the stainless steel 316L housing with opposite receiver. Thanks to the cleaning agent-resistant and robust stainless steel housing with IP69K degree of protection, even high-pressure cleaning at up to 80 °C is possible.
