What is a gasket in a connector?

Parker Chomerics connector gaskets are die-cut from premium sheet materials to provide effective EMI shielding and pressure sealing in standard and custom connector applications. They are available in sizes for all standard AN series connectors, as well as for RF types, JT, PT & PC, SO, SP, and Bendix Connectors.

What is EMI EMC gasket?

An EMI shielding gasket is a mechanical device that helps protect electronics from electromagnetic interference. Traditionally, EMI shielding has been fabricated from metal sheets and formed into shapes that fit electronic housings or enclosures.

How do EMI gaskets work?

How do gaskets work? EMI gaskets function by establishing a conductive path along seams and other openings in an electronic enclosure. This covering blocks potential difference across the shield surface and establishes a smooth current flow.

What is EMI gasket made of?

Conductive elastomer EMI gaskets. Similar to beryllium copper gaskets, these gaskets are high-performing. Made from elastomer material, such as silicone and other rubbers, and often embedded with metallic components, they require pressure to form an adequate EMI shield.

What is the purpose of EMI?

EMI shielding aims to shield a particular device or zone from interference via an effective placement of shielding materials to reduce the level of EM energy radiated by or coupled into electronic equipment.

Why EMI shielding is needed?

The main purpose of effective EMC Shielding is to prevent electromagnetic interference (EMI) or radio frequency interference (RFI) from impacting sensitive electronics. This is achieved by using a metallic screen to absorb the electromagnetic interference that is being transmitted through the air.

Why do we need EMI shielding?

How can I select EMI gasket?

Several factors must be considered when designing EMI shielding into products:

  1. Form, referring to the complexity of the form or pattern in which the gasket fits.
  2. Mechanical durability.
  3. Attenuation level.
  4. Compression.
  5. Galvanic compatibility between the gasketing conductive material and substrate metal.

Can you use aluminum shield on EMI?

Aluminum. Because of its strength-to-weight ratio and high conductivity, aluminum can work well as an EMI shield material. Compared to copper, aluminum has nearly 60 percent of conductivity.

What does the name EMI mean?

Blessed, favor, beautiful
Meaning:Blessed, favor, beautiful. Emi is a girl’s name of Japanese origin. With a definition of “blessed”, “favor”, and “beautiful”, you can hardly find a name that fits your precious girl better.

Can aluminum foil be used as EMI shielding?

Aluminum. Because of its strength-to-weight ratio and high conductivity, aluminum can work well as an EMI shield material.
