RFI and EMI - Contacts, Fingerstock and Gaskets

The 4570PA01H01200 model is a popular electrical contact produced by a wide range of manufacturers and is used for a number of applications in the aerospace and defence industries. While it is typically have a bright silver finish, the actual thickness of the plating may vary anywhere from 0.0000183 to 0.000165mm.

This contact is designed to provide excellent electrical continuity in a relatively small package. This is accomplished through the use of reinforced conductive surfaces on the contact end-face terminals, which are covered by high-performance polymers for electrical insulation. These Contact designs are precisely crafted for maximum heat dissipation, allowing them to remain stable even when exposed to extreme temperatures. The contact’s design also reduces the risk of corrosion, thereby resulting in superior mechanical life and reliability.

In addition to providing excellent electrical contact, these models are also designed to provide superior shielding against Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI). This is accomplished via the contact’s optimized fingerstock design, which effectively captures and dissipates the high-frequency energy that could otherwise interfere with nearby electronics. Additionally, the contact’s end-face tongue and groove design provides an additional layer of RFI and EMI shielding, as well as ensuring an effective electrical contact. For optimum protection, many manufacturers specify the use of additional shielding gaskets when installing the contacts, as these can provide the highest levels of protection in high-frequency environments.

The 4570PA01H01200 is ideal for many applications, ranging from Aerospace and Defence to Radio and Instrumentation applications. Its superior performance makes it ideal for use in high-frequency, low-noise applications. Furthermore, its resistance to corrosion and temperature extremes make it suitable for use in harsh environments. Its spacious contact design is also ideal for use with large signal or power cables, ensuring adequate clearances without the use of additional Expanded Polytetrafluoroethylene (EPTFE) or Kapton tape.

In conclusion, the 4570PA01H01200 model is an excellent example of a contact designed specifically for use in high-frequency/low-noise applications. Its optimized fingerstock design and high-performance insulation materials provide excellent electrical continuity and shielding against RFI and EMI. Additionally, its spacious contact design and resistance to corrosion and temperature extremes make it ideal for use in harsh environments. As such, it is an excellent choice for a range of applications in the aerospace and defence industries.
