Solenoids have become essential elements in the manufacture of electronic devices and industrial processes.
Unlike permanent magnets, solenoids generate magnetic attraction on metallic objects only when an electric current flows through their coil. This allows control of the magnetic attraction force and activation or deactivation of the magnetic field as required.
It is this versatility that has led to electromagnets and solenoids becoming indispensable components in industry, and they can be used in a wide range of sectors where controlled magnetic interactions are required.
What characteristics should be taken into account when choosing the right solenoid?
Today, solenoids are used in everything, from the manufacture of large industrial machinery to small electronic components. In order to choose the right solenoid for a specific application, several factors must be taken into consideration:
- Force: the force required depends on what the solenoid is to be used for. Consideration must be given to the load it has to pull or push. Electromagnets and solenoids are classified by their force in Newtons.
- Stroke: the stroke is the distance travelled by the plunger or armature of the solenoid. A solenoid should be selected with a sufficient stroke for the intended use.
- Size: the size of the solenoid is important for the installation and the final aesthetics of the product. An electromagnet or solenoid should be selected to fit the available space.
- Type of work: there are different types of electromagnets and solenoids depending on the work to be carried out, whether bistable, linear or rotary.
- Assembly: a solenoid must be selected with an assembly method that is compatible with the application or sector for which it is intended. At NAFSA, we offer a customised manufacturing service and we can adapt to the solution/modification suggested by the customer.
- Operating environment: the operating environment can affect the performance of the solenoid. Temperature, humidity, vibration and the presence of dust or dirt must be considered.
Other factors to consider when choosing a solenoid are noise, energy efficiency and adjustable magnetic safety features, allowing precise control according to application requirements.
At NAFSA, as expert electromagnet manufacturers, we understand the importance of choosing the right electromagnet for each industry. That is why we have developed a comprehensive guide to electromagnets designed to address the specific needs of different industries and sectors. We also have data sheets for our products with detailed information on their features and performance.
With the right guidance and a thorough understanding of your application needs, choosing the right electromagnet can make all the difference to the efficiency and success of every project.
