An interesting trend in industrial motion control has been the replacement of self-contained encoders (rotation sensors with their own housing, bearings and shaft) with modular or “kit” encoders.

Absolute encoders using optical technology often face limitations in resolution and size. For example, to achieve a higher resolution of up to 16-bits, the absolute encoder has to be combined with an ...

Precisely tracking speed, acceleration, and position of a motor's rotor is an essential requirement for many motor control applications found in everyday equipment such as fax machines, elevators, and ...

Position and motion sensor specialist Posital has announced that it has expanded its range of absolute rotary encoders and inclinometers to include support the popular Modbus RTU communications ...

Rotary encoders are indispensable tools for providing position feedback in many motion-control and automation processes. Lifts, overhead monorails, automated storage and retrieval systems, and cranes ...

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 ...
