RFI and EMI - Contacts, Fingerstock and Gaskets

The 4357PA51H01200 is an electrical contact developed by TE Connectivity. It is used to create electrical connections between two components, and is commonly used in RFI and EMI applications. It has a round profile and a hexagonal shape, and comprises two components – a contact and a gasket. The contact is made from beryllium copper material, while the gasket is made from Neoprene rubber.

Application Field

The 4357PA51H01200 Contact is used in a range of RFI and EMI applications. It is particularly suitable for those that require high electrical conductivity and a low risk of contact resistance. It can be used in applications such as information and communication technology (ICT) systems, automotive electronics, industrial control systems, and power supply systems. It is also suitable for harsh environments and is resistant to dust, moisture, and vibration.

Working Principle

The 4357PA51H01200 Contact works via the principle of ‘elastomeric fingers’. It has an internal structure made from a series of thin, flexible fingers. These fingers are called ‘Y shaped fingers’, as they have an irregular shape with an ‘L’ shaped base and a narrow tip. During operation, the contact is compressed by a small force, which causes the fingers to bend and create a reliable electrical connection. Due to the flexibility of the fingers, the contact is able to compensate for any positional misalignment between the two contact components. The contact is designed to be resistant to wear and tear and can tolerate significant force.

Conclusion

The 4357PA51H01200 Contact is an electrical connection device that has been specially designed for RFI and EMI applications. It consists of two components – a contact and a gasket – and is made from beryllium copper and Neoprene rubber respectively. It works via the principle of elastomeric fingers, which allow it to create a reliable connection despite misalignment of the two components. It is suitable for a range of different applications and is designed to be resistant to dust, moisture and vibration.
