Functional safety encoders

Functional safety encoders for motors and drives applications, cranes and hoists, wind turbines, and other automation applications in demanding environments. SIL2- and PLd- certified, robust and reliable encoders from Leine Linde are developed in close cooperation with users. By choosing a certified encoder you will simplify the certification process of your machine. 

Leine Linde’s deep knowledge about how to conveniently install and work with functional safety encoders becomes evident in the company’s different models, adaptation possibilities and solutions that can be offered:

• Functional safety certified
• Adapted for stable, safe and simple installation
• High-performance, reliable and robust
• Easy to install and integrate with safety system.

Mechanical variants with hollow-shaft and shaft mounting arrangements are available to ensure the perfect match with for example the hoist or a motor. Key, keyway, or dowel pins – many customers say that Leine Linde has the best slip-free solutions on the market, for example with the FSI 800 encoders with safe incremental signals for motor feedback. Other appreciated solutions are the FSI 900 encoders, which provide functionally safe motion monitoring with built-in safety certified limit switches. Application-specific solutions can be offered, like the FSI 900 YAWMO® with their customized, slip-free and backlash-free pinion wheels, for robust and safe mounting. 

All Leine Linde encoders have extremely high durability and accuracy, which make them the most suitable components for functional safety systems. The EU Machinery Directive 2006/42/EC and its harmonized standards have to be fulfilled for machines within the EU, but safety is more than that. Being safe means being able to trust the equipment and machinery – of course for personal safety and risk reduction, but also to know that failures and unnecessary production stops are avoided. With the right functional safety encoders, operational performance and availability will be increased!

Designing a safe system

Learn more about how to determine the safety requirements of your application in the Functional Safety brochure (pdf). There you will find information about how to use PFH (probability of a dangerous failure per hour) and MTTFd (mean time to dangerous failure) when choosing the right Leine Linde encoder for your system. All Leine Linde encoders have their PFH and MTTFd values clearly stated, for easy use when designing a safe system.
