Solenoids: the complete range for your industrial applications
Technical explanationsSolenoids for actuation, electromagnetic holding magnets, motor shaft brakes: Binder Magnetic offers a complete range of electromagnetic solutions for industry. For more than 50 years, we have helped machine manufacturers, engineering departments, and maintenance teams select and source the right components. Whether you need to pull, push, lock, or brake an element in your process, our technical teams will guide you to the product that best meets your requirements.
Single-acting solenoids are for common applications. The magnetic field delivered by the coil upon power-up attracts the core. Then, the nucleus becomes free again in the absence of current. They are thus available in different designs, folded sheet, square profiled, machined in the mass.
Double or double coil electromagnets are intended for control applications. During the respective power up, the action of one of the two coils attracts the through core. They are available in folded sheet design and machined in the mass.
Single-solenoid electromagnets are intended for applications requiring a maintenance-free position for reasons of energy saving or safety. The core is attracted by the magnetic field of the coil during power up and remains maintained by the magnetic field delivered by the permanent magnet. Then a simple inversion of the polarity of the power supply makes it possible to neutralize the magnetic field of the magnet which has the effect of releasing the core.
The bistable solenoid consists of two coils and each coil draws by energizing the through core. The magnetic field delivered by one of the two permanent magnets maintains the position. It is then necessary to reverse the polarity of the closed kernel side coil to cancel the magnetic field of the magnet. And also feed the other coil to attract the nucleus in the other direction.

What is a solenoid and how does it work?
A solenoid is at the heart of every electromagnet. It is a copper coil wound around a core. When electric current flows through it, it generates a magnetic field that moves a metal plunger in a linear motion. This principle makes it possible to perform precise actions such as pushing, pulling, orienting, or locking a mechanical component inside a machine.
This mechanism can, for example, unlock an automated locker, actuate a valve, or position a component on an assembly line. Stroke is generally only a few millimeters, with forces of around one to two kilograms. The return to the initial position is achieved by a spring or, in the case of bistable models, by a permanent magnet.
Choosing a powerful electromagnet for your application
Finding a powerful electromagnet that meets your requirements starts with clearly defining your parameters: required force, stroke, operating frequency, supply voltage, and working environment. At Binder Magnetic, we offer four main families to cover a wide range of needs: single-acting electromagnets, double-acting electromagnets, monostable electromagnets, and bistable electromagnets.
Buying a solenoid for an industrial application involves more than selecting a part number from a catalog. The environment may be ATEX-rated, the operating rate may reach several hundred cycles per minute, and the supply voltage may vary. That is why our process always starts with technical guidance.
Send us your technical specifications or engineering data, and our sales engineers will size the solution. We work with recognized European solenoid manufacturers, including KENDRION and NAFSA, to provide products that comply with DIN VDE0580 and RoHS standards.
Our standard components are kept in stock, and our workshop assembles custom electromagnets with short lead times. With five locations across France (Paris, Angers, Toulouse, Strasbourg, and Lyon) and a production facility in Orléans, we provide a level of responsiveness that few electromagnet suppliers can offer nationwide.
Applications across a wide range of industrial sectors
Our linear solenoids are used in machinery across a wide variety of sectors, including food processing, medical equipment (imaging and dialysis), rail, nuclear, defense, robotics, packaging, and automation. Whether you are an OEM designer or a maintenance manager, our range supports both new-build and replacement applications. For the most demanding projects, we can also develop a rotary electromagnet or a custom model in collaboration with our technical partners.

Frequently asked questions about industrial electromagnets
Binder Magnetic answers your questions about electromagnets.
What is the difference between a monostable and a bistable electromagnet?
A monostable electromagnet continuously draws current to maintain its working position and returns to its rest position as soon as power is removed. A bistable electromagnet remains locked in both positions using permanent magnets, with no power consumption between actuations. When a position must be held for a long time, the bistable design provides a clear energy-saving advantage.
Can I buy solenoids and holding electromagnets from the same supplier?
Yes. Binder Magnetic distributes the full range of electromagnetic products: electromagnets, holding electromagnets, brakes, clutches, and vibrators. Consolidating your electromagnet purchases with a single supplier simplifies procurement and gives you consistent technical guidance.
What are the lead times for a custom order?
For standard part numbers, our components can be shipped within 24 hours in an emergency. To buy a custom electromagnet, lead time depends on the complexity of the project. Our engineers provide a detailed quote after reviewing your technical specifications, along with a precise delivery schedule.
Does Binder Magnetic deliver throughout France?
Yes. Thanks to our five regional locations and our production facility in Saint-Jean-de-Braye (Orléans), we cover all of France, as well as Belgium, Luxembourg, and Switzerland. Each location has sales engineers who can visit your site to understand your requirements.
