Shaft IncOder features robust inductive sensor technology within a universal 58mm shaft rotary encoder package. The Shaft IncOder sensor is fully shielded from the external environments, making it the most robust absolute inductive sensor available. With a robust integral bearing design, customers can easily migrate from their existing rotary encoder to a design that is inherently robust in both mechanical design and sensor technology.
IncOders are ideally suited to harsh environments – where potentiometers, optical, or capacitive devices may prove unreliable.
