Motor encoder units combine bearing and sensor functionality into a single, compact, robust and easy to install unit. They enable accurate and continuous monitoring of speed and direction of rotation. Their sensor components are designed to be less sensitive to electromagnetic fields and provide enhanced monitoring compared to standard motor bearing units.
