How it works
When current flows through the coil a magnetic field is generated and drives the internal armature to rotate the output shaft by the preset angle. On power removal the return spring resets the armature and shaft. Typical operation provides rapid, short-angle rotation with high repeatability and low hysteresis under correct duty conditions.

Rotary Solenoid Application:

Due to their stability and compact size, rotary solenoids have many uses in industrial and commercial fields. Electric rotary solenoids are used in various applications like sorting systems, packaging systems, robot arms, valve control systems, and automation systems for fast and accurate rotary movement.

In the automotive industry, electric rotary solenoids are used in door lock systems, fuel control systems, transmission systems, headlight adjustment systems, and HVAC control modules. With the help of rotary solenoids, automotive systems become fast and reliable.

Also, electric rotary solenoids are used in the smart lock systems and security systems for controlling the actions of locking and unlocking. Moreover, electric rotary solenoids control dispensing and positioning of vending machines and self-service kiosks.

Laboratory automation, diagnostic equipment, and healthcare equipment are benefited by the accurate rotary movement of the device. Lastly, electric rotary solenoids are used in household appliances like coffee machine, smart switches, and other appliances.

How to Avoid Common Mistakes When Choosing an Electric Rotary Solenoid
Mistakes in electric rotary solenoid selection can lead to malfunction, overheating, or system failure. First of all, many people neglect the torque value of rotary solenoids.

For calculating mechanical torque output, buyers need to measure mechanical torque required for the application. The second mistake is connected with wrong voltage choice or duty cycle settings.

Coils of rotary solenoids used for continuous and intermittent duties are different in design and characteristics. Consequently, inappropriate voltage or duty cycle cause overheating and shortened life of the solenoid.

Furthermore, most buyers forget about environmental conditions for rotary solenoids such as high temperatures, humid air, vibration, and dusty environment. For industrial environments, it is necessary to apply special protection.

Wrong rotation angle causes malfunctions of the rotary solenoid in the system. Before selection, buyers need to find out the precise value of rotation angle.

Last mistake is the disregard of installation dimensions and shaft requirements. In order to avoid this problem, buyers should study technical drawings before purchase.

The final point is choosing manufacturers according to their price offers only. For the correct purchase, the manufacturing capability, engineering service, and customization ability of manufacturers need to be estimated.

How to Choose an Electric Rotary Solenoid
When choosing electric rotary solenoids, it is important to pay attention to a number of electrical, mechanical, and environmental criteria. Firstly, rotation angle and torque output must be determined for further choosing of rotary solenoids. The solenoid has to have the necessary torque output for reliable actuation without being overloaded.

Next, voltage type is very important. It usually comes in DC 12V and 24V. However, voltage used must be the same as voltage supply of the system. In addition, it is important whether the application will be operated in continuous or intermittent duty mode.

Then, response time and life are important parameters of rotary solenoids in the case of automation equipment. High repeatability is required for high-speed automated systems. Long service life is necessary for industrial applications.

Environmental parameters are important for outdoor applications. For example, high temperatures, humidity, vibration, and dust are hazardous for solenoids. Special protection should be used.Installation dimensions must be compatible with equipment structure. The size of shaft, mounting structure, connector, and cable must be measured for further rotary solenoid selection.

Finally, customization is necessary in case of OEM projects. Technical information, torque curves, and samples should be asked before choosing suppliers. Engineering service and customization capability must be considered.
