Piher sensing systems - custom potentiometers and position sensors

End of shaft position sensors

Original thinking

end of shaft sensor

Design engineers of rugged vehicles want all the benefits of Configurable Contactless Position rotary sensing (no wear and tear) without expensive overengineered
solutions to precision. They want enough accuracy plus stable performance over a long lifetime, despite environmental extremes.

Piher’s novel through-shaft sensor effectively wraps around any shaft, sensing directly at source. One slimline 9mm package contains two non-contacting components—a full-circle magnet and electronics module.
+ Application-patented design can be fitted anywhere on a shaft, giving engineers the flexibility to be creative.
+ Easy-to-assemble, so production line costs are less than those of other sensor solutions. It is ready to use!
+ No maintenance needed over the product’s life.
+ Delivers the same level of 360-degree precision and stability over at least 50 million rotational cycles as the day of installation—despite extremes of vibration, shock, temperature and contamination.
