NEWS: Rotero has a new supplier
AC solenoids, also known as alternating current solenoids, are powerful electromechanical devices that switch quickly and enable large linear movements. They are the ideal choice for applications where speed, power and precision are paramount. Thanks to their energy-efficient operation and easy installation, AC solenoids are a reliable and cost-effective solution for a wide range of industrial processes. Discover how our AC solenoids can optimise your processes.
An AC solenoid is an electromechanical device powered by alternating current (AC) to generate powerful, linear movements. Unlike DC solenoids, which are often used for continuous switching and silent operation, the AC solenoid excels in applications requiring rapid switching and large linear movements. Due to the unique properties of alternating current, an AC solenoid can switch quickly, perform powerfully and be energy-efficient.
The main differences between the types of AC solenoid relate to their switching speed, stroke length and the ability to remain on or off for extended periods. For example, there are AC solenoids optimised for heavy industrial environments, where powerful performance and rapid switching are essential. Other types are better suited to less rugged mechanical applications, where precision and large linear movements are central. Due to the absence of a rectifier, AC solenoids are easy to install and cost-efficient to use.
The features of AC solenoids make them ideal for a wide range of applications. The main properties are:
Fast switching time: they can switch quickly and accurately, which is crucial in processes where timing plays an important role.
Large linear movements: AC solenoids can perform larger linear movements compared to many other DC solenoids. They are capable of achieving stroke lengths of up to 45 mm, making them suitable for applications where a larger stroke length is required.
Energy-efficient: once the AC solenoid reaches its end position, the current consumption automatically reduces. This means the solenoid is energy-efficient and generates less heat, contributing to a longer lifespan and lower operational costs.
No extra components needed: where DC solenoids often require a rectifier to convert the current, AC solenoids do not need this component. This simplifies installation and reduces costs.
AC solenoids are often used in industrial applications where speed and power are central. For instance, they are frequently used in conveyors, where fast and powerful linear movements are essential for the efficient transport of goods. The power and speed offered by AC solenoids make them the ideal choice for these dynamic processes. Additionally, AC solenoids play a crucial role in automatic door systems, ensuring doors open and close quickly and efficiently. The fast switching time and large linear movements of the solenoid contribute to the smooth operation of these systems. AC solenoids are also widely used in heavy industrial equipment, such as presses and lifts, where large, repeated linear movements are required. Their ability to achieve larger linear movements with high energy efficiency makes them a valuable addition to machines that need to deliver high performance under demanding conditions.
Our AC solenoids are designed with attention to detail and functionality. Although AC solenoids have some limitations, such as slightly higher noise production and a lower maximum number of switching cycles per hour, they offer unique advantages that make them indispensable in specific applications. They deliver powerful performance, with the necessary force and speed. Rotero’s AC solenoids are easy to install as they do not require a rectifier, saving both time and costs. They are energy-efficient, leading to lower operational costs and a longer device life. Whether you are looking for a solution for an existing system or considering a new installation, our AC solenoids are a reliable, efficient and cost-effective option that meets your specific needs.
