In partnership with: PCAP Wire Zytronic A capacitive field is created in a pattern of conductive cooper micro-wire printed to an anti-vandal sensor glass or  flexible film, the new generation of Touch Screens are also available in multi-touch, 40 simultaneous touches, created  with a more complex patterns. In this PCAP sensors the resistance is too low and the field changes caused by the  proximity of other capacitive bodies can be very accurately measured, this field is enough powerful to be extended  through a front sacrificial glass about 12mm from the sensor, what made the most rugged and industrial PCAP  solution in the market.   Sensing Medium Behind protective glass give surface durability Technology applicable to indoor and outdoor usage. Gloved hand operation OK Unaffected by environmental conditions such as direct sunlight, rain, ice, snow and other surface  contaminants Customizable technology from 5” to 100” sensor sizes One time set up – no performance degradation or drift over time Good Optics – No front surface films or coatings used Can be sealed water tight to bezel for outdoor applications Fast response time and good positional accuracy Sensing medium can operate through various thicknesses / extra glass overlay Good impact resistance – can be tailored to specific requirements PCAP ITO  A transparent cell-pattern of Indium Tin Oxide (ITO) is applied to a substrate film and works creating a capacitive field  that changes by the proximity of other capacitive bodies. ITO sensors have good light transmission quality and they  are available in single-touch and multi-touch. However, ITO sensors are limited itself because they are not as  conductive as wire construction, so it works through a thinner surface glass and not larger touch sensors.   Comparison PCAP Wire Zytronic vs. PCAP ITO.  The processes for manufacturing ITO Touch screens are still evolving and improving and as a consequence,  their widespread industry adoption has been limited. As a result, discrete projected Touch Screens overlays  using ITO conductors remain the principal technology, at least in smaller, handheld consumer electronic  devices such as smartphones, tablets and wearables, but it suffers from drawbacks as the display size  increases beyond around 20 inches, principally as a result of its relatively high electrical resistance which  hamper its performance, and make it an unsuitable material choice for some applications. The low capacitive  field created by the ITO Touch Screens make them only workable trough very thin glasses, 1-3mm, which  make them not real anti-vandal solution. Choosing the tail position is other advantage of the PCAP wire from  Zytronic, being difficult to customize and very high-cost with ITO technology. Operating temperature is one  of the key points that make the PCAP wire from Zytronic the most robust and reliable technology working  from -35ºC to 70ºC, while ITO -20+55ªC.  Resistive  5-Wire resistive Touch Screen is the preferred solution for applications requiring durability and reliability over time.  Similar to the 4-Wire technology, 5-Wire touch screen also consists of a conductive bottom layer (ITO Glass or ITO  Film) and a conductive top layer (ITO Film). The fundamental structure different between the two is: In the 5-Wire  technology, the detected line, or the fifth silver wire, is connected to the top ITO film while, all the other four silver wire  are placed on the bottom layer. When the top layer is depressed, making contact with the up ITO layer, the fifth silver  wire picks up the voltage data and carries it to the electronics. Then, the controller can detected the touch point  Therefore, the touch screen works properly even with damages or scratches the top layer.    SAW  The Touch surface wave has transmitting and receiving piezoelectric transducers for the X and Y axis mounted  directly on the faceplate. The controller sends five-megahertz electrical to the transmitting transducer, which converts  the signal into ultrasonic waves within the surface of the glass . These wave are directed across the faceplate by an  array of reflectors.   Reflectors on the opposite side gather and direct the waves to the receiving transducer, which reconverts them into  an electrical signal. The process is repeated for each axis. When you touch the screen, you absorb a portion of the   waves traveling across it. The received signals for X and Y are compared to the stored digital maps, the change is  recognized, and a coordinate is calculated.  © Iberhermes 2017 Terms and Conditions  /  FAQs
