Magnetic Connector

Particularly in the medical technology, automotive and e-mobility sectors, we have already been able to implement a large number of magnetic connector solutions for our customers.

Magnetic connectors: Space-saving & design-oriented

The trend towards increasingly slim and design-oriented construction of HMI devices makes the integration of standard connectors difficult. Spring contacts are available in very small designs. Particularly space-saving is the arrangement of the contact pins in the so-called right-angle design, whereby contacting can be implemented in a very small space. Our magnetic connectors mostly consist of spring contact probes and a magnetic connection system. We design and manufacture the magnetic connectors to suit the customer’s application.

Currents up to 15A per pin

Spring contact probes transmit not only charging currents, but also all other types of signals. Depending on the material and internal structure of the spring contact pin, currents of up to 15A per pin are possible. This is a decisive advantage especially for the charging time of high performance batteries.
In our product range of spring contacts we offer more than 300 different standard pins, which we select to fit your application. Customized manufacturing is also possible.
Conventional connector systems require a certain insertion depth for optimal locking. Magnetic plug-in solutions can be implemented with a very flat and planar design. This makes them particularly interesting for applications in the medical field. This is because elevations, gaps and crevices in particular pose a high risk of contamination. The flat magnetic connectors, on the other hand, can be cleaned and disinfected very easily.

Self-guiding connection

The implementation of magnets ensures a self-guiding, as well as shock- and vibration-resistant connection between plug and device. This means that even very small plugs can be connected to sockets relatively easily in difficult installation situations. The polarity of the magnets also means that incorrect connection can be ruled out. The magnetic force can be adjusted to customer specifications by using different magnets. Examples include: Charging cables of smart watches or e-bikes.

Another advantage of a magnetic release mechanism is that in case of an unintentional pull on the cable, the end device will not be damaged by a fall. Likewise, the tearing out of integrated sockets in walls, e.g. in bed controls in hospitals, can be prevented in this way. But this type of safety mechanism has also proven its worth in household appliances. In the case of kettles, the pull on the cable caused by overturning can lead to bad scalds. This danger can be avoided by using a magnetic connector.

Protection class IPx7 and higher

For more demanding installation situations, where protection classes of IPx7 and higher are required, we offer various connector designs. On the one hand, the pins can be supplemented with an O-ring seal, on the other hand, there is the possibility of direct over-molding with plastic and/or sealing with elastomer materials.
Magnetic connectors offer high functional and contact reliability, as well as a shock and vibration-resistant connection.

Simple product relaunch with magnetic plug-in adapters

With customer-specific plug adapters, magnetic cable solutions can be easily integrated into existing operating systems. In this way, proven input devices can be relaunched without any complications. We design and supply magnetic cable solutions with plugs based on spring contacts.

Magnetic micro USB connector

To ensure a secure connection between plug and mobile device, even when there is constant movement, a standard Micro USB plug was equipped with a circumferential magnet (silver).

 

Magnetic Round Connectors

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

 

Customized cable with magnetic connector as a complete system

In the example, the connector consists of four spring contact pins and a permanent magnet. This ensures a quick shock and vibration-resistant connection between the plug and the device. The special shape of the plug ensures a reliable connection to the housing. For this project, N&H took on the cable assembly and the production of the housing.

We realize magnetic connectors including cable assembly for all sectors and industries. We are happy to take over the design and development.

Using 3D printing and manual processing, we can create individual magnetic connectors for customer-specific applications in advance. This “mini-series” contains up to 20 samples and is suitable for the first installation and testing of the magnetic force. In addition, necessary changes can be identified and implemented early on in the design phase. In our Product area Pogo Pins we offer over 500 different standard pins that we select to suit your application. Customer-specific productions are also possible.

Does the designed fit and meet all expectations? Then the serial tool is created for further series production.

For a first inquiry we need a rough description of the application, required specifications, and the planned quantities of serial production.
Our engineers and product designers look forward to assisting you with your project.
