Endress+Hauser FTE20 Series Paddle Limit Switch Level Switch, Threaded Mount, ATEX-Rated, Housing Polycarbonate

This level switch is a compact point detector designed to monitor liquid presence in industrial installations. Built for threaded mounting, it provides straightforward integration into tanks and vessels where a discrete high/low interface signal is required. The device is intended for use in potentially explosive atmospheres and carries the necessary hazardous area certification for such environments.

• Operates between -20°C and 60°C to handle varied process temperatures
• Accepts up to 230V AC to interface with common mains systems
• Supports 28V DC for low-voltage control circuits
• Withstands pressure up to 10 bar for elevated internal tank conditions
• Silicone sealing ensures compatibility with many liquid media
• Polycarbonate housing provides impact-resistant enclosure

• Suitable for threaded installation on storage tanks and vessels
• Ideal for point-level detection in pumping stations
• Used with control panels requiring AC or DC switching inputs
• Can be used for high/low alarm generation in processing plants
• Appropriate for deployment where ATEX certification is mandated

It is designed for screw-in installation using a threaded mount to secure into standard port fittings on tanks and pipework.

The unit provides switching compatibility for both mains-voltage AC circuits and low-voltage DC circuits, enabling connection to a range of control and alarm systems.

The polymer construction reduces corrosion risk and simplifies cleaning, while enabling visual inspection without exposing internal components.

A silicone gasket provides the primary seal between housing and process connection, chosen for its chemical tolerance with many liquids.
