The flexible membrane keyboard

Control your machines
with a custom HMI

You manufacture a machine, a piece of equipment, a device, we develop your custom Human Machine Interface for you! It will be unique, will ensure the communication of your image, will implement the required functionalities and will be adapted to the conditions of use of your industrial environments.

What is a flexible keyboard made of?

We offer full customization of membrane keyboards: the design and functionality are adapted according to your specifications.

Depending on the HMI's development environment, we are experts in screen or digital printing on polyester, polycarbonate, soft-touch, and bayfold. This decorative side can then be deformed or embossed to ensure the expected tactile sensation.

Work in a protected area ESD (Electro-Static Discharges): our facilities and procedures allow us to handle components up to ESD class 1A according to standard JESD22-A114C.01.

The backlight: Many HMIs require uniform backlighting, allowing them to operate in dark environments (railway, mining, etc.). Our teams have developed multiple techniques to offer you backlighting of an area on the front panel such as your logo, a pictogram to highlight or one or more keys in particular.

Control of support forces: We offer you a keyboard construction adapted to the support forces of your specifications. The tactile sensation is an important element of your project that we take into account from the study phase.

Waterproofing: We deliver HMIs that meet IP67 and IP68 standards. These requirements can be tested within the group or in the laboratory.

Operation over time: The number of keystrokes is guaranteed (from a few hundred thousand to a few million). A test bench has been designed and developed to test the evolution of the keys and the electrical signal as they are pressed.

EMC issues: Our expertise allows us to build keyboards by adding shielding elements to contribute to the overall protection of the equipment against electromagnetic waves.

Capacitive or resistive keyboards: Our teams can support you in your capacitive or resistive HMI projects, i.e. for which a simple contact of the operator's finger on the plastic or metal surface is enough to create the contact.

Keyboards equipped with capacitive or NFC antenna: For an application such as access control, it is possible to screen print or print antennas that allow contactless exchange of information between a user and the HMI.

Quality assurance and control methods

We test all the features of every keyboard that leaves our workshops. Each compliant keyboard then receives a unique identifier allowing for the traceability of its manufacture and inspection.
The checks carried out are documented in a control plan that can enrich your ISPs and DVIs.

Functionality

100% of manufactured keyboards are tested before serialization on versatile electrical test benches. It is possible to use a test bench of your supply.

Traceability through serialization of each keyboard

100% of the HMIs leaving our factories are guaranteed by our Quality Management System processes.
