QUELL EESeal filter inserts in stock at Astute

These inserts transform standard circular, D-Sub, Micro-D, and custom connectors into shielded, filtered versions in seconds, significantly simplifying EMI/ESD compliance efforts.

The common source radio frequency (RF) noise from a product design comes through the conductive cables from device to device. Wavelengths leaking through these paths can result in interference.

One solution has been the development of filtered connectors, which incorporate shielding material structured around the hardware of the connector assembly.

A newer approach to connector EMC has been EESeal filter inserts from Quell. These silicone precision inserts form a tight fit around the pins of most connectors. Design engineers can shunt noise at the same output point of a filtered connector and achieve comparable results.

Lab testing—as well as thousands of real-life cases of successful EMI compliance—demonstrate the reliable performance of EESeal filter inserts to suppress RF noise. Additionally, the inserts stand up to a wide range of harsh environmental conditions from altitude and immersion to shock and vibration.

Designed for applications where shielding effectiveness, space constraints, and cost are critical factors, QUELL eSeals excel in industries including medical equipment, defence systems, industrial automation, and other sensitive electronics. 

Their unique construction features a silicone elastomer body infused with conductive particles, ensuring long-term reliability, environmental protection, and effective signal filtering.

By choosing QUELL EESeal inserts, engineers gain several key advantages:

• Eliminate the need for specialised filtered connectors
• Streamline design by integrating filtration into existing connector footprints
• Reduce overall system weight and size
• Maintain excellent EMI and ESD shielding performance
• Benefit from a wide range of standard sizes and customisation options

To further simplify the design and evaluation process, Astute Group provides free samples of QUELL EESeal inserts to engineers.  This allows for hands-on testing and ensures the perfect fit and performance within specific applications.
