Algra Group l Dynaforce



DYNAFORCE is a design-related solution for input systems.

Force touch • 3D touch • Met­al touch • Design • Van­dal­ism • Hygiene
With this HMI tech­nol­o­gy (Human Machine Inter­face), pres­sure-depen­dent input sys­tems can be designed.

Thanks to the ultra-sen­si­tive strain gauge sen­sors, touch pan­els made of a wide vari­ety of mate­ri­als can be oper­at­ed gen­tly, even met­al touch fronts made of stain­less steel and alu­minum. At the same time, DYNAFORCE is more robust, more water­proof and less prone to fail­ure than oth­er solu­tions. The best thing to do is to see for your­self.

Industry sectors:

Med­ical tech­nol­o­gy, pub­lic con­trol sys­tems, san­i­tary con­trols, machines and indus­try, house­hold appli­ances


DYNAFORCE Module Scheme

Integrated signal evaluation

“With more than 30 years of experience with piezo input systems, we know all the pros and cons of piezoelectric switching sources. Now we are replacing piezo technology with a new, improved system: We call it DYNAFORCE.”

Dieter Mat­ter — Chief Exec­u­tive Offi­cer

DYNAFORCE is unique on the market and offers the following advantages:

  • The solu­tion is also extreme­ly sen­si­tive on met­al sur­faces (met­al touch).
  • Oper­a­tion with gloves is pos­si­ble with­out any prob­lems.
  • The appli­ca­tion also works very well in wet, cold and hot con­di­tions.
  • Thanks to met­al sur­faces you have pro­tec­tion against van­dal­ism.
  • Assem­bly is extreme­ly easy.

A whole new touch

Touch screens have con­quered the world. With DYNAFORCE it is now pos­si­ble to design touch-sen­si­tive sur­faces out of wood, glass, plas­tic, chrome steel or alu­minum. The new solu­tion thus offers count­less new oppor­tu­ni­ties for user-friend­ly appli­ca­tions.

“When you turn a piece of wood or metal into a touchpad after a short assembly, then it’s a goose bumps moment.”

Joshua Fajar­do – Project Man­ag­er DYNAFORFCE

What sets our HMI input system apart from other technologies?

DYNAFORCE is unique on the mar­ket and offers you the fol­low­ing advan­tages:

Exclusive design

The front pan­el can be made from a con­tin­u­ous met­al lay­er (met­al touch). Any mate­ri­als are con­ceiv­able as a
con­trol sur­face.

Better usability

Oper­a­tion is just as sen­si­tive when wear­ing gloves as with­out.

Highest water protection class

DYNAFORCE can be ful­ly oper­at­ed
when it is wet.

Protection against vandalism

Thanks to stur­dy met­al oper­at­ing pan­els, the solu­tion is resis­tant to van­dal­ism.

Force touch

Adjustable key­stroke or key­stroke-depen­dent oper­a­tion.

Wide temperature range

DYNAFORCE can be used between ‑40 ° C and +85 ° C.

Long lifetime

The test­ed life­time is over 10 mil­lion cycles.

Easiest assembly

It is assem­bled using self-adhe­sive tape (peel-and-stick).

Individual layout

You are free to arrange the keys as long as you keep the min­i­mum dis­tance
between the keys.
