What are HMI components?
HMI (Human Machine Interface) components form the interface between humans and machines, thus enabling safe, intuitive, and reliable operation of technical systems. The spectrum ranges from simple input elements to complex control units.
Our solutions include, among others:
- Membrane keyboards and front panels
- silicone keymats
- plastic and metal housings
- Displays and display units
- Connectors and spring contacts
In doing so, we take into account not only functionality, but also factors such as feel, design, protection class, EMC behavior and lifespan.
Application
We use our customer-specific components in various industries and adapt them specifically to the respective requirements:
- Medical technology, especially for hygienic applications
- Industrial automation and mechanical engineering
- Mechanical and plant engineering with high load requirements
- Measurement technology and laboratory technology
- Automotive and special vehicles
This results in solutions that are optimally tailored to the respective application, both technically and economically.
Technical Design & Customization
We develop our components specifically for each project, adapting them precisely to the respective operating conditions. In doing so, we consider both technical and economic requirements and adjust all parameters accordingly.
Among other things, we take the following into account:
- Protection classes up to IP69K and special sealing concepts
- Temperature resistance and environmental influences
- mechanical and electrical load capacity
- Lifespan and switching cycles
- Material selection, e.g. silicone, plastic or metal
- Haptics and ease of use
- EMC requirements and shielding
This results in solutions that not only integrate perfectly into your products, but also function reliably in the long term.
From idea to series
We accompany you throughout the entire development process and ensure a structured and efficient implementation:
- Consulting and concept development

FAQ
Which HMI components are suitable for my application?
We analyze your requirements and the specific operating conditions and recommend the most suitable solution based on this analysis. In doing so, we take into account both the application area and the technical and economic parameters.
What quantities are possible?
We produce both small and large series, offering you economical and scalable solutions that can be flexibly adapted to your needs.
How long does the development process take?
The development time depends on the specific project scope and technical requirements. In many cases, however, initial prototypes can be implemented within a few weeks and subsequently further optimized.
What types of protection are possible?
Depending on the design and materials used, solutions up to IP69K are possible. We take into account both environmental influences and the specific requirements of your application.
I don't have my own design – can you still support me?
Yes, we will support you even if no design or concrete plan yet exists. Together with you, we will develop a technically suitable solution based on your requirements and operating conditions. We will assist you not only with concept development, but also with material selection, design, and manufacturing-oriented planning. This way, step by step, a product is created that can be implemented optimally, both functionally and economically.
