Standards for sensors in sterile environments

Previously, decontamination was considered sufficient for sensors and reflectors installed in a way that interrupted first air. Annex 1 "Manufacture of Sterile Medicinal Products Guideline" requires that these components also be treated with validated, penetrative sterilisation methods (e.g., autoclaving).

The image show an example of an Annex 1 compliant solution: Leuze ToF sensors mounted on the side or underneath the product reliably detect it without entering the first-air area, so the sensors do not need to be sterilised.
