Leak-proof proTect+
Baumer sensors have been developed to guarantee exceptional sealing throughout their entire service life. While other sealing tests only test sensors for water tightness when new, the proTect+ testing process primarily simulates the aging effects of sensors. After aging, the sensors are subjected to tightness tests in accordance with specific IP protection class guidelines to guarantee tightness.
What is proTect+?
proTect+ is a sealing concept developed by Baumer that ensures long-term functionality of the sensor even in the harshest conditions. To guarantee the special sealing of the sensors, great attention is paid during development to the selection of the right materials and optimizing the design. Comprehensive stress tests according to proTect+ guidelines check the long-term sealing of the sensors.
First, test sensors are subjected to water temperature or air temperature shock tests, simulating the effects of aging and thus the life cycle of a sensor in the machine. Each sensor must go through 50 temperature cycles in total. Then, tests are applied in accordance with IP x8 and IP x9 protection classes.
Selected materials:
proTect+ uses V4A/V2A stainless steel, chemical nickel-plated heat-treated steel, NBR, liquid silicone rubber, polyamide and other materials to ensure special sealing. Additionally, the smooth and impermeable surfaces prevent dirt and bacteria from adhering to the sensors with the hygienic design, allowing simple and thorough cleaning of the sensor.
Optimized design:
It is designed to ensure absolute tightness even at critical points such as mechanical interfaces, cable exits or LED switching status indicators, even with foam or high-pressure cleaning.
Test series proTect+
They are subjected to extensive stress tests to guarantee the absolute tightness of the sensors. The following tests are performed on multiple sensors:
Air temperature cycle test
Temperature shock testing in air with 50 temperature cycles over the entire temperature range of the sensor.
Water temperature cycle test
Temperature shock test in water over the entire temperature range of the sensor, up to a maximum of +85°C.
IP x9 test
Water jet proof and high pressure cleaning proof test according to DIN EN 60529 standard.
IP x8 immersion test
The sensors are kept one meter below the water surface for 168 hours.
