Sick's W4S-3 INOX photoelectric sensor
The W4S-3 INOX photoelectric sensor features an IP 69K stainless-steel housing. The W4S-3 incorporates OES3 technology into the custom application-specific integrated circuit (ASIC). These sensors are designed to ignore stray background reflections, detect multi-colored or shiny objects and provide high immunity to ambient light. They feature a smooth, stainless-steel housing to reduce the risk of bacteria growth that can result when food particles become lodged in the housings' small grooves or crevices.
