แผงสัมผัสแบบมีสาย 4 (ET-4W-4W-4′ ความต้านทาน 15 จุด )

Introduction of the 4W resistive touch panel
4-wire resistive touch screen is an outstanding high quality product, suitable for low cost solution. It is inherently of many advantages such as high accuracy, quick response, drift-free, stable and long durability for a life time of 1, 000, 000 times finger touches. Keep touch 4 wire resistive touch screen featured contamination-resistant and waterproof, is designed for the harshest environment such as dust is prevalent or liquid spills, splashes and wash down. It can be touched by finger, gloved finger, leather or stylus pen.
