Краткое описание: Parker Chomerics CHO-TOUCH™ EMI Shielded Touchscreens combine today’s state of the art touchscreen technologies (PCAP and Resistive) with our industry leading EMI shielding expertise
Parker Chomerics EMI Shielded Touchscreens combine today’s state of the art touchscreen technologies with our industry leading EMI shielding expertise. Touchscreens are in a wide range of military and industrial products. They are being speci?ed in more ruggedized applications such as military, homeland security, ?rst response and medical where EMI shielding is required. A touchscreen fully integrated with an EMI shield simpli?es the compliance with these tough EMI requirements.
Parker leverages its materials science and lamination skills to integrate EMI shielding materials with the most speci?ed types of touchscreens, including resistive and projected capacitive. Various shielding materials are available, such as: ITO conductive coatings, blackened plated stainless steel mesh and blackened copper mesh. These highly transparent conductive ?lms and specially designed ?ne wire meshes can be selected for the best optical and EMI shielding performance. EMI shielding is fully integrated into the touchscreen assembly with no air gaps or voids using optical grade PSA.
Parker has stock EMI shielded resistive and projected capacitive touchscreens. Parker can integrate a customer-supplied touchscreens or procure a speci?ed touchscreen. We assist with the design of an appropriate EMI shield based on the application requirements. The EMI shield will be optically bonded to the rear of the touchscreen and the required buss bar termination will be applied. CHO-FOIL® Copper tape can be used to wrap the buss bar to the front side of the touchscreen to provide a ground plane. In addition, our shielded touchscreens can be provided with a wide variety of conductive gaskets for assembly into bezels and frames.
