Special applications

Hygienic and washdown zones, Detecting transparent objects, Detecting small objects

Housing design

Hygiene ⁴⁾

Mounting hole

¹⁾ Reflective tape REF-AC1000.
²⁾ Average service life: 50,000 h at T_U = +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.
