Individual magnetic connector solutions

We realize magnetic connectors including cable assembly for all sectors and industries and are happy to take on both the design and development. Depending on the material and internal structure of the spring contact pin, currents of up to 15A per pin are possible. In addition, the magnetic force can be customized by using different magnets.

For particularly demanding installation situations, we can offer protection classes up to IPx7. Our solutions not only guarantee high performance, but also high reliability and safety in a wide range of application areas.

Please here Just let us know if you are interested in a magnetic connection solution. For an initial evaluation of your request, a first sketch, the desired specifications, as well as the planned annual volume and duration is sufficient.

Design-oriented solution

Our magnetic connector solutions are extremely popular in the fields of medical technology, automotive and e-mobility. The integration of standard connectors is becoming more and more difficult due to the trend towards ever slimmer and design-oriented construction of HMI devices. Space-saving and modern, magnetic connectors are perfect for applications where traditional connectors are no longer sufficient. With spring contact pins and a magnetic connection system, our magnetic connectors can be individually designed and manufactured depending on the customer application.

Spring contacts with currents up to 15A

Our spring contact pins not only transmit charging currents, but also all other types of signals. In addition, we offer over 300 different standard pins in our Spring contacts product range which we select to suit your application. In addition, customer-specific adjustments to the specifications, such as nominal current, spring force or coating, are also possible. Depending on the material and internal structure of the spring contact pin, currents of up to 15A per pin are possible, which is a decisive advantage, especially for the charging time of high-performance batteries.

While conventional plug-in systems require a certain insertion depth for optimal locking, our magnetic plug-in solutions can be implemented with a very flat and flat design. This makes them particularly interesting for applications in the medical environment. They can also be cleaned and disinfected very easily because they do not have any bumps, gaps or crevices that would pose a high risk of contamination.

Self-guiding connection

Thanks to the implementation of magnets, our connectors ensure a self-guiding, shock- and vibration-resistant connection between the connector and the device. This means they can be used without any problems even in difficult installation situations. In addition, the polarity of the magnets prevents incorrect connection and the magnetic force can be adjusted to suit customer requirements. Our magnetic connectors are perfect for charging cables for smart watches or e-bikes, to name just a few examples.

In addition to functional and contact security, magnetic plugs also offer a magnetic release mechanism that protects end devices if the cable is pulled unintentionally and prevents integrated sockets in walls from being torn out. This is particularly important in hospitals and with household appliances such as kettles, as the pull on the cable can cause severe scalding if it falls over. This danger is avoided by the magnetic connector.

Protection class IPx7 and higher

We also offer various connector designs to meet the requirements for protection class IPx7 and higher. The pins can be supplemented with an O-ring seal, directly overmolded with plastic and/or sealed with elastomer materials. These designs offer additional safety and are particularly advantageous in demanding installation situations. In addition, our magnetic connectors ensure a shock- and vibration-resistant connection, ensuring reliable and secure transmission.

Easy product relaunch with magnetic plug adapters

Magnetic cable solutions can be easily integrated into existing operating systems using customer-specific plug-in adapters. In this way, proven input devices can be given an uncomplicated relaunch. We design and deliver magnetic cable solutions with connectors based on spring contacts.

In order to ensure a secure connection between the connector and the mobile end device, even when the device is in constant motion, a standard Micro USB connector was fitted with a surrounding magnet (silver).

Circular connectors with magnetic guidance can be designed to be particularly small and space-saving. In addition, the design allows 360° rotations with constant contact.

In the example, the plug consists of four spring contact pins and a magnet, which ensures a quick, shock- and vibration-resistant connection between the plug and the device. In the customer-specific example, the magnetic connector is made up of two power and data lines. In addition, the special shape of the plug ensures a reliable connection to the housing. By implementing the socket directly in the housing, both assembly times and costs are reduced.

Optimal locking with a flat design

In contrast to conventional plug-in systems, which require a certain insertion depth for optimal locking, the magnetic plug-in system enables a very flat design. In this project, we took over both the cable assembly, including the magnetic connector system, and the production of the housing.

We offer customized magnetic connectors for various sectors and industries, including design and development. Using 3D printing and manual processing, we can create individual magnetic connector prototypes for customer-specific applications. This “mini series” with up to 20 samples enables initial installation tests and tests of the magnetic force. This method allows necessary changes to be identified and implemented in the design phase.

In our spring contacts product range, we offer over 300 different standard pins that can be selected to suit the respective application. In addition, customer-specific production is also possible. After checking the designed connector and meeting all expectations, we create the tool for series production.

In order to make an initial inquiry, we need a rough description of the application, required specifications and planned quantities. Please send us this data by e-mail info@nh-technology.de.

We would also be happy to conclude a non-disclosure agreement/NDA with you in advance. Our engineers and product designers look forward to supporting you with your project.
