Cam Positioners
Cam Positioners are a type of electronic components that achieve precise position control based on the principle of mechanical cams. They play a key role in industrial automation, precision instruments, and other fields.
1. What are Cam Positioners?
Core Components
The combination of mechanical cams and sensors (such as resolvers) is used to achieve preset motion trajectories through the geometric characteristics of the cam profile.
The new Roller Cam Positioners have developed into a multi-degree-of-freedom adjustment system that supports X/Y/Z axis translation and rotation positioning, and uses a rolling bearing structure to reduce friction loss.
Drive Mode
Early models relied on mechanical linkage, and now they are mostly integrated with servo motors or stepper motors to achieve closed-loop control.
The high-end models in 2025 are equipped with a LabVIEW programming interface and wireless control module to support remote positioning calibration.
