What Is a Rotary Connector?
Rotary connectors facilitate electrical connections between rotating and stationary components. They are crucial for powering rotating parts or transmitting signals and data from sensors on rotating parts to stationary control units.
Commonly, rotary connectors contain liquid metal, such as mercury or gallium alloys, to maintain conductivity. They find application across diverse fields including industrial machinery, automotive, medical equipment, and telecommunications, significantly contributing to technological advancements.
Applications of Rotary Connectors
Rotary connectors bridge rotating and stationary parts, which is crucial for devices with electronic components on rotating sections. They eliminate the risks associated with cable connections, such as disconnection or short-circuiting, by considering contact friction and electrical characteristics in their design. In the industrial machinery sector, they are integral to automated processes, featuring rotating machines like machine tools and robots.
1. Automotive Industry
In the evolving automotive sector, rotary connectors are vital for the transmission of signals and power among numerous electronic control devices. They support the seamless integration of functions such as entertainment systems, sensors, and airbags.
2. Medical Equipment Field
The demand for rotary connectors in medical technology is high, especially in surgical robots and diagnostic equipment, enabling precise operations and data gathering through rotational signal transmission.
