3-20T-ZNC-24 RF/IF and RFID

RFI and EMI - Contacts, Fingerstock and Gaskets:

RF/EMI shielding is a crucial component of any remote or home circuitry. In order to prevent interference between analog and digital signals, manufacturers often utilize a variety of components that help reduce the amount of interference that can be produced in a circuit. The 3-20T-ZNC-24, which falls under the RFI and EMI contact, fingerstock, and gaskets umbrella, is just one of the many ways circuit boards can be protected from RF/EMI interference. This article will address the application field and working principle of the 3-20T-ZNC-24.

Application Field:
The 3-20T-ZNC-24 is an EMI contact designed for use in shielding devises that protect the circuitry from RF/EMI interference. It includes a variety of features that make it suitable for both radio frequency interference (RFI) and electromagnetic interference (EMI) shielding. These features include a full-assembly connection, an overmolded grip for easy installation and removal, an anti-rattle pressure plate for stability, and a stainless steel fingerstock for durability. It is designed to provide high-performance RF/EMI shielding, operating up to 30GHz. It is also designed to be an economical solution in today’s market, providing excellent protection for a fraction of the cost of other shielding technologies.

The 3-20T-ZNC-24 is suitable for a wide range of uses, ranging from preventing interference in communication networks to military applications where maximum RF/EMI protection is required. It can also be used in many different types of test doas, including microwave-based and VHF/UHF-based test doas.It has been designed to provide superior performance characteristics when compared to other shielding technologies.

Working Principle:
The 3-20T-ZNC-24 uses a combination of fingerstock and gaskets to provide an efficient way of reducing the amount of RF/EMI interference that can be passed into a circuit. The fingerstock, also known as metal fingers, are a type of flexible material that form a frame for contact against another surface, such as the cover of a shielding case. The gaskets are placed between the fingerstock and the casing to reduce the amount of RF/EMI interference that can pass through. The gaskets are usually made of materials such as EPDM or silicone, which can be used to affect the amount of electrical conductivity that can transfer through the boundary of two different substrates.

The 3-20T-ZNC-24 also utilizes a pressure plate to help maintain the contact between the fingerstock and the casing. The pressure plate is mounted on the casing and is designed to be mechanical in nature and not rely on other electrical components. Once the contact has been made, it is then sealed and soldered into place. This ensures that the RF/EMI interference is kept as low as possible and that the contact remains secure. This type of contact is highly effective and provides an excellent shielding solution for a variety of applications.

In conclusion, the 3-20T-ZNC-24 is an effective shielding technology for use in a variety of shielding scenarios. It offers a combination of fingerstock and gaskets to reduce the amount of RF/EMI interference that can be transferred into a circuit, as well as a pressure plate to help maintain the contact between the fingerstock and the casing. It also offers an economical solution when compared to other shielding technologies, providing high-performance RF/EMI shielding at a fraction of the cost. This makes the 3-20T-ZNC-24 an excellent choice for any application where RF/EMI protection is needed.
