How to shield the gaps in the panel of an electrical force measurement switch (PMS)?

Openings in the PMS panel, such as displays, indicator lights, and buttons, disrupt shielding continuity and are major pathways for electromagnetic leakage. Addressing these gaps requires a comprehensive approach using conductive materials, filtering, and layout techniques. For large openings like displays, use transparent conductive films (such as ITO films) or metal mesh-layered shielding glass, ensuring a tight seal to the metal panel around the edges with conductive gaskets. For small openings like indicator lights and buttons, use components with metal housings, ensuring direct contact between the housing and the metal surface of the panel opening during installation, or use conductive rubber gaskets. For unavoidable assembly gaps (such as the panel-cabinet joint), use highly elastic electromagnetic sealing gaskets (such as beryllium copper springs or conductive foam), with compression reaching 30%-70% of the design value. All cables passing through the panel (such as power lines and communication lines) must be connected via metal feed-through capacitors or filter connectors, ensuring a 360° conductive connection between the connector housing and the panel. These measures can reduce electromagnetic leakage from panel gaps by 20-30 dB while maintaining overall shielding effectiveness.
