Functional safety encoders for industrial applications

A safe production starts with control. It takes precise calculations and exact measurements of movements for production to keep going. Being in control of every step of the chain – to keep you, your machines and your business safe.

Leine Linde always strives to offer some of the best and robust products on the market. That’s why our new range of Functional Safety Integrated products (FSI) guarantees one of the highest safety standards of the automation industry. Sensors and encoders made to predict and prevent accidents before even happening – keeping things under control.

Being safe is essential for productivity. For protecting human lives and preventing financial loss, and taking responsibility for the future. So stay in control and be safe with the next generation of encoders and sensors from Leine Linde.

Safety is our priority

At Leine Linde, we are the experts in functional safety encoders. The best encoders are those you never have to think about. Those that simply do their job – year after year. We develop and manufacture customized encoder solutions for demanding environments, advanced measuring systems for accurate feedback of speed and position.

Rigorous testing

All our safety products undergo rigorous testing at every step of the design and production process. This thorough approach ensures that our products meet the highest safety regulations and standards. From initial design to final assembly, each component is carefully checked to guarantee reliability and performance in the most demanding environments.

Certification standards – SIL and PL

There is a growing awareness of the standards regarding safety. Most companies are using standards ISO 13849-1 and/or IEC 62061. ISO focuses mainly on mechanical engineering and the value is called PL. While IEC focuses more on electronics and electronic systems and safety level is called SIL.

PROFIsafe

We use PROFIsafe for safe communication. PROFIsafe is a communication protocol used in industrial automation, designed specifically to enhance functional safety within PROFINET networks. It ensures the safe and reliable transfer of data between safety-related devices, such as sensors, controllers, and actuators, in industrial settings.

More about PROFIsafe

PROFIsafe is a communication protocol used in industrial automation, designed specifically to enhance functional safety within PROFINET networks. It ensures the safe and reliable transfer of data between safety-related devices, such as sensors, controllers, and actuators, in industrial settings.

Key Features of PROFIsafe:

Error detection and correction: PROFIsafe provides mechanisms removing the possibility of errors in the communication, ensuring data integrity in critical safety applications.

Seamless integration: PROFIsafe operates as an additional layer to PROFINET that fulfils the functional safety requirements without additional wiring or infrastructure (black channel principle)

Encoder redundancy: The mechanics and electronics operate with redundancy, meaning even if there is a failure in one value it will always be correlated and detected to maintain safe operations.

Fail-safe mechanisms: In any case of communication or scanning errors in a FSI product alarms and warnings will be sent to intended controllers.

Why use PROFIsafe?

Enhanced safety: PROFIsafe ensures that safety-critical systems, such as emergency stops or machine protection mechanisms, operate reliably, preventing accidents and reducing risks in industrial environments.

Compliance with safety standards: It complies with international safety standards like IEC 61508 (Functional Safety of Electrical/Electronic/Programmable Systems), helping industries meet regulatory requirements.

Cost efficiency: PROFIsafe eliminates the need for separate safety networks by integrating both standard and safety communication into a single network. This reduces installation costs, wiring complexity, and maintenance efforts.

Flexibility and scalability: It allows for the flexible design of automation systems, supporting both small-scale and large-scale safety applications in various industries, including manufacturing, robotics, and process automation.

Improved productivity: By enabling safe automation, PROFIsafe reduces the likelihood of downtime due to accidents or equipment failures, improving overall operational efficiency.

SIL and PL – two safety certification levels

What is SIL and PL levels in safety certification? The purpose of SIL and PL is identical. The main differences are that standard 13849-1 (PL) provides a broader framework and includes pneumatic and hydraulic systems. Standard ISO 13849-1 (PL) focuses mainly on mechanical engineering, while standard IEC 62061 (SIL) focuses more on electrical and electronic systems.
