EMI Shielding Gaskets for Connectors
What are Quell’s EESeal EMI Gaskets?
Quell’s EESeal® Gaskets are innovative, flexible EMI/RFI filter inserts designed to fit seamlessly into existing connectors. Unlike traditional bulky filtering solutions, EESeal gaskets are thin, elastomer-based components embedded with conductive elements that provide effective electromagnetic interference (EMI) suppression and environmental sealing. They are custom engineered to deliver robust filtering performance while maintaining the integrity of signal and power lines, all without requiring connector modifications or redesigns.
What sets EESeal gaskets apart is their versatility and ease of integration. They can be quickly installed into circular (MIL38999, MIL5015, MIL26482, etc.), D-sub, or custom connectors, offering immediate EMI protection and environmental sealing in harsh conditions. Their unique design ensures strong electrical contact for EMI shielding while acting as a physical barrier against dust, moisture, and vibration.
Add Grounding to Individual Pins
Sometimes you can solve an EMI issue with an external grounding shield. But with our unique seal technology, you can selectively ground pins from inside the connector. Pop in one of our gaskets to target specific pins with conductive or non-conductive treatments.
What are the different types of EMI Gaskets?
With a custom EESeal gasket, each connector pin can be paired with miniaturized conductive and non-conductive treatments based on your application’s specific EMI protection requirements. Conductive materials are ideal when direct grounding is required, while non-conductive materials are better suited for isolating components and preventing direct electrical connections.
When are EMI Gaskets Used?
EMI gaskets are engineered to create a conductive pathway between two surfaces, serving as a shield against electromagnetic interference. Gaskets fill gaps where interference is most likely to affect an electronic system — the inputs and outputs — effectively blocking EMI from entering or leaking from the design.
Whether you’re working on military-grade equipment, aerospace systems, or industrial applications, EESeal gaskets provide custom, high-performance EMI/RFI suppression with more convenience and lower cost than off-the-shelf solutions.
