DYNASIM Piezo Keypad Technology
Patented DYNASIM® keypad technology has revolutionised the use of Piezo switching by automating the manufacturing process, allowing piezo keypads to be used in high volume applications.
DYNASIM® Keypad technology consists of patented piezo ink layers, electrical conductors and insulators printed on polyester film using a screen printing process. A key press generates a charge which is used as a switch signal which is then interfaced to the control electronics. See How to Interface Piezo Keypads.
By using robust overlay material, DYNASIM keyboards are extremely strong and offer resistance against vandalism with an anticipated life time of 50 million operations. Variable switch sensitivity and attractive aesthetics ensure a great user experience, whilst the overall depth of the keypad construction also allows for simple integration in to an electronic system
Ideal for High Volume Applications.
DYNASIM® keypad technology combines all the advantages of DYNAPIC keypads. However due to its unique printed Piezo elements which are mass produced using automated printing methods, DYNASIM offers attractive prices for high volume applications.
Benefits of DYNASIM Keypads
- Various overlay materials possible
- EMC shielding integrated
- Extremely robust
- Competitive high volume pricing
- Curved form possible
- Choice of key size
- Vandal resistant
- Adjustable sensitivity
Interfacing Piezo Keypads:
ALGRA offers its own custom ASIC interface controller which amplifies and digitalizes the piezo – electrical signals produced by the keyboard.
These CMOS signals are available as serial, parallel and as a matrix for further processing. Other standardized interfaces are also available.
The switch sensitivity is set electronically through the adjustment of the switch point on the ASIC. This setting can be made when the interface is manufactured at our internal electronics laboratory or is offered in software form to the user.
