An electromagnetic door holder is an essential component in industrial access, control and electromagnetic safety systems.
At Bobinados Osés, we develop solutions for OEM manufacturers, integrators and industrial companies that require reliable systems for the remote opening, closing and holding of doors using electromagnets.
Unlike standard off-the-shelf products, our solutions are designed to meet the specific functional requirements of each application. We manufacture custom electromagnetic door holders and other electromagnetic door solutions for integration into intercom systems, access control systems, industrial equipment and safety applications.
In addition to manufacturing electromagnetic coils, we can supply complete subassemblies ready for integration into industrial production processes. This allows us to combine our coils with the surrounding components required to create complete electromechanical assemblies.

Custom electromagnetic door holder manufacturing
Manufacturing an electromagnetic door holder for an industrial application requires technical expertise, flexibility and in-depth knowledge of industrial processes. Each project involves specific requirements relating to operating voltage, frequency of use, holding force, dimensions and mechanical integration.
For this reason, we work closely with engineering and R&D departments to develop customised OEM solutions according to the technical requirements of each project.
We manufacture electromagnetic solutions for applications including:
- intercom systems
- remote door opening systems
- industrial automation
- electromagnetic locking systems
- access control
- industrial safety systems
Our custom electromagnetic door holders can be manufactured in industrial production runs and adapted to the customer's engineering requirements, while other door electromagnets can be developed for applications requiring different operating principles.
Compared with a generic product, a custom solution can improve electromechanical integration, optimise durability and facilitate production scalability. An electromagnetic system developed for a specific application can also provide more stable performance and greater operational reliability.
Electromagnetic door holders for industrial access systems
Electromagnetic door holders and other door electromagnets are used in industrial systems where fast actuation and operational reliability are essential. Depending on their design, these electromagnetic devices can safely and efficiently activate opening, closing or holding mechanisms.
We develop specific solutions for manufacturers that need to integrate an electromagnetic holding or locking device into more complex electromechanical subassemblies.
Remote door opening and closing using electromagnets makes it possible to automate access points without relying on complex mechanical systems or sliding-door automation. These solutions are particularly useful in industrial access systems, intercom systems and safety applications.
Types of electromagnetic solutions for industrial doors
Different electromagnetic configurations can be developed depending on the application, required holding force, installation conditions and operating environment.
Surface-mounted electromagnets
Surface-mounted electromagnets are commonly used in industrial access systems due to their ease of installation and maintenance.
Their configuration can be adapted to different mechanical requirements, making them suitable for applications where accessibility and straightforward integration are important.
Electromagnetic door locks
An electromagnetic door lock is used in security and access control systems where reliable electromagnetic locking is required.
These solutions can be engineered according to the required holding force and the electrical and mechanical integration requirements of the application.
Choosing the right electromagnetic door lock depends on factors such as the type of access point, required holding force, operating conditions, available space and the safety requirements of the system. For OEM projects, the electromagnetic door lock can also be adapted to specific electrical and mechanical integration requirements.
Shear electromagnetic locks
Shear electromagnetic locks provide high holding forces in applications where installation space is limited.
Their compact configuration makes them suitable for access systems that require high retention capacity within restricted installation dimensions.
Electromagnetic door holders
An electromagnetic door holder is particularly important in door retention, fire safety and evacuation systems.
Depending on the application, the device can hold a door in a defined position during normal operation and automatically release it when an alarm or emergency protocol is activated.
This operating principle is especially relevant when the device functions as a fire door holder, as the door must be released when required by the corresponding safety system.
Integration of complete electromechanical subassemblies
One of the advantages of working with Bobinados Osés is our ability to supply complete subassemblies in addition to custom electromagnetic door holders and other door electromagnets.
Depending on the project, we can supply assemblies that are:
- fully assembled
- wired
- equipped with integrated connectors
- tin soldered where required
- ready for integration into industrial production
By combining manual assembly processes with automated operations, we can improve repeatability, optimise production times and maintain consistent quality control.
This capability allows OEM manufacturers to source a more complete solution instead of managing the integration of each electromagnetic component separately.
Electromagnetic door holders for safety and retention systems
The electromagnetic door holder plays an important role in industrial safety and evacuation systems, particularly when doors must remain in a defined position during normal operation and be released automatically under specific conditions.
Typical applications include:
- fail-safe systems
- electromagnetic door holding
- integration with fire alarm systems
- automatic door release
- fire doors
Fail-safe systems are designed so that the door is unlocked or released automatically in the event of a power failure or emergency.
This principle is particularly important in a fire door holder, as the electromagnetic holding device must release the door when the corresponding alarm or emergency system is activated.
UNE-EN 1155 regulates electrically powered hold-open devices for swing doors, including applications involving fire and evacuation systems.
Sistemas Fail-Safe vs Fail-Secure
The choice between a fail-safe and fail-secure configuration depends on the purpose of the installation.
In applications where evacuation and personal safety are the priority, fail-safe operation allows the system to release when electrical power is lost. In access protection applications, a fail-secure system may instead be required to remain locked.
Remote door opening and closing using electromagnetic systems facilitates the safe automation of industrial access points and technical installations.
Depending on the application, the appropriate solution may therefore be an electromagnetic door holder, an electromagnetic door lock or another customised electromagnetic mechanism.
| Feature | Fail-safe | Fail-secure |
|---|---|---|
| Status without power | Unlocked | Locked |
| Priority | People safety | Asset security |
| Typical application | Evacuation and emergencies | Access protection |
| Common use | Electromagnetic systems | Electric locks |
Custom electromagnetic door holders for OEM projects
At Bobinados Osés, we work with industrial manufacturers throughout the different stages of a project.
Our capabilities include:
- technical development
- prototyping
- industrial validation
- series production
- production scalability
- quality control
We develop custom electromagnetic door holders and door electromagnets for integration into demanding industrial environments.
Our experience in electromechanical integration allows us to develop robust and reliable solutions adapted to OEM production requirements.
Instead of limiting the project to a standard catalogue component, we can adapt the electromagnetic solution to the mechanical, electrical and production requirements of the customer's system.
This approach is particularly useful for OEM manufacturers that require custom electromagnetic door holders designed around their equipment, rather than having to modify their equipment around the specifications of a standard product.
