EMI & RFI-Shielding Touchscreens

These shields are especially useful for companies operating within the industrial, military and healthcare sectors.

Zytronic’s EMI & RFI shields

We can provide touch solution shields that prevent EMI and RFI, reducing interference from other devices or surrounding activity without compromising on efficacy.

There are two main types of interference when it comes to touchscreens:

• Conducted noise – usually generated from power supplies, cable signals and board wiring.
• Radiated noise – emitted through the air.

Using an electromagnetic interference-shielding touchscreen or a radio frequency interference-shielding touchscreen can prevent severe disruption of essential communications and data handling. An effective shielding system will also contain any emitted signals from your equipment, preventing electronic eavesdropping.

Our EMI and RFI shields are an extension of the Faraday cage principle, with fine wire mesh or metal oxide films acting as a barrier to the interference. The holes in our mesh shields are smaller than that of the wavelength it is shielding against, in order to effectively prevent interference.

Zytronic’s shields alone will not solve all EMI and RFI interference issues, but should be utilised as part of a fully shielded system.

We can also provide EMI and RFI shields for non-touch solutions if required for your specific project.

Sector applications

RFI and EMI-shielding touchscreens can be utilised for a number of applications. They are especially effective when used within:

• medical devices
• military devices
• transport communication devices, such as those on ships and aircraft
• industrial settings
• ATMs
• gambling touch solutions, such as casino slot and table touchscreens
• secure areas.

Zytronic’s EMI and RFI shields will help equipment work at an optical efficacy level, when used in conjunction with a full shielding system, in these areas and beyond.
