Hazardous Locations (Ex)
In environments where explosive atmospheres may occur, strict regulations govern how electrical equipment must be designed to minimize the risk of ignition.
Leine Linde offers certified encoders for both positioning and speed feedback, specifically developed to meet these safety requirements. Thanks to their robust construction, our encoders are ideal for use in demanding and hazardous environments, ensuring reliable performance even under extreme conditions.
What is a Hazardous (Explosive) Environment?
Hazardous locations—also known as explosive (Ex) environments—are areas where flammable gases, vapors, dust, or fibers may be present in concentrations that could ignite under certain conditions. These environments are common in industries such as oil & gas, chemical processing, mining, and grain handling. In such settings, even a small spark from electrical equipment can pose a serious safety risk.
To ensure safety, strict regulations govern how equipment must be designed and certified for use in these areas.
How our products operate in EX Environments
Leine Linde encoders are engineered to deliver reliable performance in the most demanding and hazardous environments. Whether for positioning or speed feedback, our Ex-certified encoders are built with robust mechanical construction and sealed housings to prevent ignition sources from interacting with the surrounding atmosphere.
These encoders are designed to withstand:
-
High mechanical stress
-
Vibration and shock
-
Moisture, salt, and dust
-
Extreme temperatures
This makes them ideal for continuous operation in harsh industrial conditions.
Certifications and Safety Standards
Our encoders meet internationally recognized safety standards for use in explosive environments, including:
-
ATEX (EU directive for equipment in explosive atmospheres)
-
IECEx (global certification for Ex equipment)
-
SIL and PLd (for functional safety in automation systems)
These certifications ensure that our products comply with the highest safety and reliability requirements.
