The leading and longest established online Process Engineering publication serving the Process Manufacturing Industries ...

Rotary and linear optical encoders are common in position and motion sensing. Here, a disc or plate containing opaque and transparent segments passes between an LED and detector to interrupt a light ...

Every encoder-based motion-control axis, such as a servo motor or step motor, must know where it is to be accurate. If it doesn’t, it will never reach its target position. But the encoder must first ...

Last year, Automation World examined the differences between accuracy, resolution, and precision in the encoder world. And while understanding the differences among these terms is important to ...

Suited for severe electrical and physical environments, the DS90-DB-10-2 absolute encoder convert shaft input to BCD or binary information corresponding to the shaft angle with an accuracy of ±1 pt in ...

Position encoders are sensors that, when used in industrial settings, produce critical motor information such as speed and position. The encoder delivers data for display or data that may serve as ...
