Why Use an ATEX Position Switch?

In explosive atmospheres, position switches must operate without generating any spark. They ensure safe and reliable machine monitoring by allowing you to:

• Precisely detect the position of a door, hatch, valve or moving component.
• Control automation systems safely.
• Protect operators and industrial processes.
• Prevent incidents such as overtravel, jamming or mechanical collisions.
• Ensure ATEX/IECEx compliance of your installations.
• Resist extreme environments (dust, humidity, saline atmosphere, hydrocarbons).

These switches are essential to avoid unexpected shutdowns, explosion hazards and accidents on high-risk industrial sites.

Industrial Applications of ATEX Position Switches

ATEX position switches are used across a wide range of industries where mechanical movement must be controlled with absolute reliability:

• Refineries, oil terminals, offshore platforms.
• Chemical, pharmaceutical and cosmetics industries.
• Silos, sugar plants and food processing (combustible dust).
• Paint, solvent and flammable product installations.
• Power plants, turbines, generator sets.
• Conveyors, hoists, industrial lifts and rotating machinery.
• Technical rooms, machine rooms, confined areas.
• SEVESO sites or strictly regulated hazardous zones.

Wherever a machine or mechanism must be monitored, an ATEX position switch is indispensable.
