Leine Linde introduces a SIL3 approved PROFIsafe encoder
FSI 608 sets a new standard in safety for automation
Leine Linde is proud to launch a comprehensive new safety range alongside the cutting-edge FSI 600 series. The series is a family of safety-certified rotary encoders, engineered to meet the highest functional safety standards. With this initiative, Leine Linde enables industrial players to enhance workplace safety while meeting growing global regulatory demands.
As safety requirements in industrial automation continue to rise, so does the need for certified, high-performance safety products. Leine Linde’s new solution delivers on both – helping leading manufacturers protect people, machinery and production environments worldwide.
"We’re excited to launch the FSI 600 series – a breakthrough in encoder technology that enhances functional safety and delivers reliable performance even in the toughest industrial environments. It’s rewarding to know this innovation will help make industrial sites safer," says Pär Lundström, Product Manager at Leine Linde.
600 series – where safety meets performance
The FSI (Functional Safety Integrated) 600 series marks a significant step forward in Leine Linde’s portfolio.
Key benefits of the FSI 600 series:
- SIL3 and PLe category 4, functional safety compliance – certified for use in the most demanding safety applications.
- Absolute inductive sensing – durable, contactless technology for long-term reliability in harsh environments.
- Safe multiturn – know your position even after a power off.
- PROFIsafe over PROFINET – ensures safe communication in real-time industrial networks.
- Designed for tough conditions – engineered to perform in environments with high shock, vibration and temperature variations.
FSI 608 – safety for automation
The first product in the FSI 600 series, FSI 608, is a unique safety encoder that fully complies with the latest standard: IEC 61800-5-3, covering functional, electrical and environmental encoder safety. FSI 608 is among the first encoders on the market to meet this level – positioning Leine Linde as one of the earliest achievers of certification under the new regulation.
With multiple mechanical options, scalable resolution and comprehensive built-in safety functions, the FSI 608 offers easy integration into diverse automation setups.
"The best encoders are the ones you never have to think about — they just keep working, year after year. The FSI 608 encoder gives you precise control at every step. If something breaks, drops or simply isn’t right, FSI 608 responds immediately — helping prevent accidents before they happen," concludes Pär Lundström.
