# RLS AksIM-2 Redundant Off-Axis Absolute Encoder (two readheads)

![RLS AksIM-2 Redundant Off-Axis Absolute Encoder (two readheads)](https://parts.trymaglev.com/img/ac-rls-aksim-2-redundant.webp)

AksIM-2 ring read by two electrically isolated readheads 180° apart, giving two independent position channels for joints that need functional-safety style redundancy.
