Hygienic Design for Machine Vision Lighting in Food & Beverage
An IP69K rating tells you whether water and dust gets in. It says

chemistry, or whether its shape drains. Here is what else
decides whether a component belongs on a washdown line.

Machine vision now runs on food and beverage lines that are washed down hard and often, an environment most cameras, lights and lasers were never built for.
This paper sets out three pillars for specifying components that survive it: ingress protection, material science and geometric design. It also covers the certification landscape, the hygiene zones, and the difference between a rating that is self-declared and one independently verified.
