Photoelectric sensor for wash down environments
Sick, a manufacturer of sensors, safety systems, machine vision, and automatic identification products for factory and logistics automation, has launched its W4S-3 Inox photoelectric sensor. The sensor features a smooth, IP69K stainless steel housing that withstands harsh wash down applications in the food and beverage, pharmaceutical, solar, and semiconductor industries, Sick says. The W4S-3 incorporates OES3 technology into Sick’s third generation custom ASIC (application-specific integrated circuit) to provide the best background and foreground suppression in the market, the company says. These new sensors, which expand Sick’s existing IP69K product offering, are said to ignore stray background reflections, detect multi-colored or shiny objects, and provide high immunity to ambient light. Their smooth, stainless steel housing reduces bacteria growth that can result when food particles become lodged in the housings’ small grooves or crevices. This durable housing also gives the sensor a longer lifecycle, reducing replacement and downtime costs incurred when sensors frequently fail.
