Automatic sliding doors are an increasingly widespread solution in industrial, commercial, and security environments. Their proper operation largely depends on an essential component: the electromagnet. These devices ensure a secure, controlled closure that integrates seamlessly into automated systems, making them a critical element in any modern installation.
What are electromagnets for sliding doors?
Electromagnets generate a magnetic field when they receive electrical current. In the case of sliding doors, this principle is mainly applied to keep the door locked in the closed position, release the lock in a controlled manner when the corresponding signal is received, and integrate with automation and access control systems.
Advantages of electromagnets in sliding door locking systems
Electromagnets offer a series of advantages over other mechanical locking systems:
- Guaranteed security: they keep the door closed with constant force until an electrical opening signal is received, which is especially important in installations with access control or restricted areas.
- Integration with automated systems: they can be easily connected to access control systems, presence detectors, alarms, and industrial automation, making them an ideal solution for intelligent sliding doors.
- Reliability and long service life: with fewer mechanical components subject to wear, electromagnets provide greater durability and consistent performance even in high-use environments.
- Fast and precise response: electromagnetic actuation allows very short response times, essential for high-traffic automatic doors.
Types of electromagnets for sliding doors
Choosing the right electromagnet will depend on the type of installation and the security requirements of each project.
Linear electromagnets are the most commonly used system in these cases. They keep the mechanism closed or open depending on the need. When activated, the electromagnet releases the system, allowing the door to open or close.
Linear electromagnets, such as the CU20/CP, are used when a locking or latching function is required, as they can absorb lateral forces without damaging the guide. They actuate internal components with high precision, making them very useful in automated doors with specific technical requirements.
In many industrial or high-security projects, the best option is to develop custom solutions that combine different types of electromagnets according to the specific needs of the installation.
What factors should be considered when choosing an electromagnet for sliding doors?
To ensure proper system operation, it is important to consider the holding force required by the mechanism, the type of operation needed (fail-safe or fail-secure), frequency of use, environmental conditions (temperature, humidity, presence of dust), and compatibility with the existing automation system. Choosing the right electromagnet not only improves door performance but also increases safety and reduces maintenance costs.
At NAFSA, we design and manufacture electromagnets for sliding door locking systems, adapting to the specific needs of each project and installation. In addition to our standard range, we offer custom manufacturing options, developing tailored solutions that ensure perfect integration and optimal performance in any environment.
