HMI Technologies that Keep You at the Forefront of Innovation, Ideal for Today’s Rapidly Changing Markets
Barantech’s Piezo Technology
About the Piezoelectric Effect
Barantech piezoelectric switches and keypads harness the piezoelectric effect – a property exhibited by certain crystals that generate voltage when subjected to pressure, without requiring an external power source.
Application of Piezo Technology Explained
Barantech’s unique piezo switches feature VPM (Versatile Piezo Module) – a mechanical structure containing all the necessary switch components, that are press-fit into a solid metal housing. Thus, when pressed, the piezoelectric crystal material produces a corresponding change in voltage, which passes through a conductive connecting material to a circuit board mimicking a dry-contact switch closure. In addition, our unique modular approach eliminates the need for a solder connection to the delicate piezo ceramic and creates a robust 125 msec. minimum switch closure, which is a significant improvement over market standards of just 20 msec.
Piezoelectric switches, keypads and control panels do not require an external source of power and offer very different advantages over capacitive or membrane switches.

Smart Functionality that Gives Users Greater Control
Barantech’s HMI systems and control solutions feature built-in software and proprietary algorithms that expand operability and user functionality. Our smart technologies support a range of functions beyond a simple momentary switch closure – prolonged, toggle, continuous, programmable and slide switch functions. They also provide self-diagnostic reporting capability and switching of line voltages, putting more control in your hands and those of your users.

Touch-Free Infrared Technology
Barantech’s proprietary infrared technology offers cutting edge, hygienic touchless switching solutions. This IR technology, that offers a motion-activated solution that detects a finger or a hand at a distance of approximately 5 cm, is combined with the benefits and functionality of a fully programmable, customizable and easy-to-retrofit switch. This solution is particularly suited for high traffic applications, and those where hygiene is vital. It enables non-touch actuation for a wide variety of devices used in different public and commercial environments – from public transport through healthcare institutions to retail stores, and more.
