Emerson’s GO™ Switch Proximity Sensor Overcomes Packaging Line Washdown Challenges

Food and meat packaging lines rely on caustic washdown to eliminate contamination, meet government standards, and ensure safe products. In these expensive applications, the washdown's sodium hydroxide solution is highly corrosive to the proximity sensors that indicate conveyor, elevator, gate, and flap positions.

For food packaging applications, one sensing solution stands out. Emerson’s TopWorx™ GO™ Switch is ideally suited for caustic washdown conditions. It detects like a proximity switch, yet functions like a limit switch — providing a more rugged alternative to an inductive proximity sensor and far more reliability than a reed switch. In UL Laboratories' hot and cold endurance testing, the GO Switch has operated to 1 million cycles. Its specially coated stainless-steel construction resists corrosion and is easily washed and sanitized. A wide range of electrical approvals ensure use in any production environment. Plus, its low-temperature rating (-40° C) is suitable for refrigerated or frozen food processing.

The GO Switch gives end users lower maintenance costs and greater flexibility in monitoring different types of equipment. For OEMs, it simplifies design complexity and eliminates the cost of work-around components.
