How to choose connection cable of touch screens?

In practical touch screens installations, the selection of connecting wires often requires comprehensive consideration of signal quality, environmental factors, and cost control. The technical team of Shenzhen Xinlilai Touch Technology Co., Ltd.  provides you with professional technical advice based on years of experience.
 

The signal transmission quality of USB cables in touch screens is the most concerned issue. Our high-speed USB cable adopts a twisted pair design, with a transmission speed of up to 480Mbps, fully meeting the needs of 4K touch screens. It is worth mentioning that we have also developed a dedicated USB cable with a magnetic ring, which can effectively suppress high-frequency interference. This is particularly useful in medical equipment and other situations where high signal purity is required. Recently, in a digital signage project at a hospital, this USB cable helped solve the signal interference problem that had long plagued customers.
 

Terminal wires have unique advantages in signal stability in touch screens. Due to the use of direct crimping connection, signal attenuation is much smaller than that of USB cables. Our latest developed multi-core shielded terminal wire has signal attenuation controlled within 3% at a distance of 30 meters, which is close to the standard of professional grade video cables. For scenarios such as factory automation equipment that require long-distance stable transmission, terminal wires are undoubtedly the best choice.
 

Although DuPont lines are not suitable for long-distance transmission, they play an irreplaceable role in signal testing. Our engineers highly recommend using color coded DuPont wires, which can greatly reduce wiring errors. In a recent touch screens R&D project, after using our color DuPont line, the commissioning efficiency was improved by 40%, and the project cycle was shortened by nearly two weeks.
