Emerson Electric's TopWorx MTS is designed to deliver trusted performance in applications from standard industrial to extreme-duty.

The hazardous locations-approved TopWorx MTS provides ready-to-install, universally certified position sensing for explosion-proof and intrinsically safe applications.


The MTS is a magnetic, target-actuated, barrel-style switch designed to deliver trusted performance in applications ranging from standard industrial to extreme duty. Featuring universal certifications including IECEx, ATEX, UL, and CSA, the TopWorx MTS can help reduce time to market by avoiding approval delays.


Available in general purpose, intrinsically safe or explosion-proof area classifications, the 316 L stainless steel design of the MTS resists corrosion, making it suitable for use in environments including oil & gas, chemical, industrial energy, on-site utilities, mining, minerals & metals, power generation, pulp & paper, waste, and wastewater.
