Fingerstock provides superior durability and high-current grounding but requires more precise mechanical tolerances. Foam gaskets are more forgiving, cost-effective, and better suited for irregular enclosure gaps.
RFI and EMI - Contacts, Fingerstock and Gaskets Component Intelligence
Engineered shielding solutions for enclosure integrity and electromagnetic compatibility.
What are RFI and EMI - Contacts, Fingerstock and Gaskets components?
EMI/RFI contacts and gaskets are critical for maintaining Faraday cage integrity in electronic enclosures. Selection depends on the required shielding effectiveness (dB), compression force, material galvanic compatibility, and the physical mounting geometry of the chassis.
How to Choose RFI and EMI - Contacts, Fingerstock and Gaskets Components
Selecting the right shielding hardware requires balancing mechanical constraints with electrical performance requirements.
Shielding Effectiveness
Determine the required attenuation in dB across your target frequency range to select appropriate material density.
Galvanic Compatibility
Match gasket material to enclosure plating to prevent long-term corrosion and loss of electrical contact.
Compression Set
Ensure the gasket material maintains its shape and conductivity after repeated compression cycles.
Mounting Geometry
Choose between clip-on, adhesive-backed, or surface-mount contacts based on your assembly process.
Environmental Factors
Consider temperature, humidity, and vibration, which may degrade conductive fillers or adhesives over time.
