Magnetic Latches Types and Selection

Magnetic Latches Types and Selection Guide.

Magnetic latches have many differences from traditional mechanical latches and are changing the way we approach locking mechanisms. Although the various styles and types of magnetic locks provide unique conveniences for different applications, they cause “difficulty in choosing” for some buyers. I have listed 6 common types of magnetic latches and analyzed them in detail from 7 aspects, hoping to give you clear and practical selection guidance.

What are the Different Types of Magnetic Latches?

Magnetic latches may seem like a simple widget, but they’re a versatile solution. The wide variety of magnetic latches available today can perfectly match almost any design and functional need. Different types of magnetic latches are tailored for different levels of complexity and application needs. It is important to thoroughly evaluate specific requirements before choosing the right latch. Let’s take a look at the most common types of magnetic latches and how they work so that you can make an informed decision.

Magnetic Door Latch (Powered Magnetic Latch)

An electric magnetic door latch is exactly what it sounds like: a magnetic latch that requires electricity to control the closing effect. They are often used on automatic doors or latch systems that require remote or automatic control. These electric latches use electromagnets to generate holding force, but they are divided into two types due to the different ways they provide security:

  • Fail-Safe Latches When power is applied, the electromagnet attracts the door latch or strike plate, firmly holding the door or panel in place. When power is removed, the latch automatically releases, allowing the door to open. Usually used in priority opening situations, such as emergency exits and stairwell doors.
  • Fail-Secure Latches require power to unlock. It will remain engaged off during a power outage. Fail-safe locks are essential in applications that require a constant secure closure, such as server rooms, switchboards, high-security doors, and secure storage environments for sensitive information or valuable equipment.

Surface-mounted magnetic latches

Surface-mounted magnetic latches are one of the simplest and most common types of magnetic latches available. These latches mount directly to the surface of a door or panel. The ease of installation allows it to be used in a variety of settings, from furniture doors to storage cabinets.

These simple magnetic door latches typically consist of two main components: a magnet and a corresponding metal plate. The magnet is mounted to the moving body (door or shutter) and the metal plate is fixed to the door frame. When the door is closed, the magnet attracts the latch, holding the door securely in place.

Hidden magnetic latches

For luxury furniture or hidden compartments, concealing the latch inside the door or door frame can provide a more aesthetically pleasing and simple look. Unlike surface-mounted latches, hidden magnetic latches achieve closure by applying a magnetic pull in a “shear” direction rather than a direct pull. These door latches do not show any external components when the door is closed. The magnet is embedded inside the structure, making them ideal for applications where aesthetics or a simple design are critical.

Simple Latch Magnets

Sometimes, the simplest solutions are the best. Latch magnets are just that – an easy-to-use and affordable option. It is widely used in small applications that do not require complex mechanisms or power systems, simply keeping the door closed and simply opening it when required.

Heavy-Duty Magnetic Latch

Heavy-duty magnetic latches are made of strong magnets (usually neodymium or other rare earth materials) + protective coatings, which can withstand large forces. For industrial and commercial applications, heavy-duty magnetic latches are designed to provide greater holding force to secure large doors or panels. It is usually used for doors that need to be opened and closed frequently such as production workshops, warehouses or airports, hospitals or shopping malls.

Magnetic Contact Latch (Push to Open)

Handleless designs are everywhere in modern and stylish home and office designs. Magnetic contact door latches play a big role behind the scenes: with a light push, the door latch will release and open the door or panel. This latch makes our living spaces more minimalist without sacrificing convenience.

How to Choose the Right Magnetic Latch for My Application?

Choosing the right magnetic lock when there are so many types can seem like a challenging task. I believe you will have a question in your mind at this time: “How do I know which one is best for my application?”. Don’t worry, by considering a few important factors we can make a decision with confidence.

  1. Match retention
    Holding force is the force provided by the Magnetic Latch to keep the door locked: the greater the holding force, the more secure it is, and the greater the force required to open it. Think about how strong the latch needs to be to hold a door, panel, or lid firmly in place without much resistance when opening it.
    Cabinet doors or small storage closets don’t require strong retention, and regular surface-mount latches will suffice. For heavier doors, consider a more powerful heavy-duty magnetic latch. It is important to match the magnetic strength of the Magnetic Latches to the weight of the door or panel you are securing.
  2. Materials of construction are important:
    The structure of the magnetic lock is that the outer structure wraps the magnet, and the outer structure material can be plastic or aluminum alloy. The material will directly affect the durability of the magnetic latch: plastic magnetic latches are affordable and easy to customize, aluminum alloys are lightweight and rust-resistant, and stainless steel is hard but slightly more expensive.
  3. Evaluate the external environment:
    Where do you plan to install the magnetic latch once you get it? Is it a humid environment, a hot space or a beautiful office or home environment?
    For hot environments, you need a high-temperature resistant magnetic latch that can withstand these extreme conditions. For wet environments, such as marine applications or humid climates, be sure to choose a latch with a waterproof coating or material. Stainless steel or nickel-plated, epoxy-coated door latches work well in these situations.
    Matching latches to specific environmental challenges ensures they last longer and perform more consistently.
  4. Size fit:
    See how much space you plan to install the magnetic latch in. If space is limited, a compact magnetic latch will be more suitable. If you are securing a larger industrial door, you will need a larger size latch to withstand the load. Make sure the latch you choose fits the available space and has enough holding power to support the weight it needs.
  5. Mounting style:
    Magnetic door latches have different mounting styles, some require precise alignment, while others are more forgiving. Surface mount door locks can be installed quickly with few tools and can often be retrofitted to an existing door or panel. Installing concealed magnetic latches within a door or door frame often requires professional installation skills and more time to install securely.
  6. Aesthetic Preference:
    In interior design or custom projects, appearance is often as important as function. Surface-mounted magnetic latches are generally more visible, so they are better suited for practical applications where appearance is less important.
    In those applications where appearance is important (high-end cabinetry or luxury furniture), reducing the exposure of hardware is necessary. This is where hidden door locks or beautifully designed latches come into play.
  7. Budget:
    This is a turn-off factor. As with any product, budget is an essential consideration. Although magnetic strikes are affordable enough, prices still vary depending on strength, materials, and design.
    If your budget is limited, a simple magnetic strike or surface-mounted latch is a cost-effective choice. For automated systems or luxury furniture, you will need to invest more in high-performance or concealed magnetic latches.

There is no “one-size-fits-all” latch. Every application scenario is unique, and taking the time to carefully evaluate your immediate needs will lead to better results in the long run.By considering the factors listed above, you can certainly make an informed decision.

What Are the Benefits of Using Magnetic Latches Over Traditional Latches?

When it comes to securing doors, cabinets, or gates, there are a variety of latches to choose from. Of these options, magnetic latches are becoming increasingly popular. What exactly makes them more popular than traditional mechanical latches like spring latches or knob latches?

We all know that magnetic door locks can pull or push the door or panel directly for smooth operation, allowing for instant and easy closing. It has very few moving parts inside, with no mechanical components to line up or knobs to turn. This simple latch design is durable and will not cause parts to wear out over time.
In contrast, traditional mechanical latches have either a rotating button or a spring mechanism inside. More effort is required during use. In addition, the mechanical parts inside traditional latches will inevitably wear out under long-term and frequent use. In the long run, traditional mechanical door locks may require more maintenance.

Another highlight of magnetic door locks is their quiet and self-attracting closing method. When closing the door with a magnetic door lock, the attraction of the magnet will smoothly pull the two parts together, and there is almost no noise (unless you slam the door when closing).
Traditional mechanical latches with internal springs or knob latches that click or pop into place during engagement can be particularly jarring in noise-sensitive environments.

Magnetic door locks also have advantages in terms of design and aesthetics. In particular, their simple structure allows us to design them to be more compact and stylish than traditional door locks. No need for numerous cumbersome mechanical parts. In particular, the hidden magnetic door locks mentioned above can be designed to be hidden inside the door or panel, providing a clean, modern appearance.

While magnetic door latches offer many advantages over traditional mechanical latches, the same cannot be said for security. Traditional mechanical latches physically insert bolts or pins into the receiving parts when locking, forming a real staggered security connection. The magnetic retention force provided by magnetic latches can only be used for doors that do not need to be locked but still need to remain closed. For example, in the kitchen, bathroom or wardrobe… situations where safety requirements are not high.

It is undeniable that traditional door locks still have a place in high-security or industrial applications, but magnetic door locks have many advantages in daily use. It is a user-friendly and more aesthetically pleasing choice. Besides, they are not enemies. In application scenarios that require frequent opening and closing and require a certain degree of safety, we can use both traditional door locks and magnetic latches. In this way, the magnetic latch can maintain a simple and convenient normally closed effect when opening and closing frequently. When you need to get off work or completely close the cabinet, you can use the key to make the traditional mechanical door lock work.

Magnetic door locks are not only powerful, but also stylish, which is unmatched by mechanical door locks. This is why magnetic latches are becoming more and more popular in daily life. I believe that through my explanation, you will already have clear requirements for the magnetic latches you need.
