A safety scanner can detect an obstacle, but it does not by itself guarantee that the vehicle understands its real speed and braking behavior accurately enough. That is where the safety encoder becomes important in AGV architecture.
Its role is directly linked to functional safety, speed monitoring and controlled stopping performance. In practice, this makes it a critical component for both compliance and predictable behavior in mixed-traffic environments.
