1) Reflective tape REF-AC1000.
2) Average service life: 50,000 h at TU = +25 °C.
3) External teach-in: pulse > 2 s with voltage Uv with PNP and M with NPN.
4) Difference between standard/washdown and hygiene: The essential difference between a standard/washdown product and a hygiene product is that where the process and contact with the medium (activity in the vicinity of the food) are concerned, a hygiene product is designed in accordance with the latest standards and hygiene design guidelines, and materials are selected accordingly.
