Safety absolute encoders EN580RS – in robust design

Save as PDF

The EN580RS encoders are a safe solution to deliver rotary position and speed data. They are safety certified according to IEC 61508 (SIL 2)/ ISO 13849 (PL d/ Cat.3), and are ready to use in your control and safety plan.

The encoders are designed for reliability and safety functions in harsh environments, especially in mobile machines (vehicles in construction, commercial/municipal, agriculture, forestry, material handling, etc.) and outdoor applications. They are particularly suitable in applications with the presence of people such as loader cranes, gripper arms, hoists with free hanging loads, moving platforms, etc.

The devices support superior machine uptime by robustness against environmental influences, shocks, vibrations, extended EMC interferences, and media contact. Their position and speed acquisition support fast movements due to their very short internal process time. With their position acquisition architecture and their CANopen Safety interface, the encoders can be directly integrated into control and safety plans, to enable simple machine certification, and to improve application and process control.
