8864-0110-72

The 8864-0110-72 contact system is a preassembled contact module, consisting of precision stamped contacts, fingerstock, sealing gaskets, and accessories. It has been designed to provide a superior solution for protecting electrical equipment from RFI and EMI that may be caused by external sources or even within the system itself. RFI and EMI (radio frequency interference and electromagnetic interference) can impair electrical performance, harm data, and cause safety issues. This type of contact system provides a reliable barrier and an effective grounding contact to protect against such interference.

Application Field and Working Principle

The 8864-0110-72 contact system is widely used in a range of applications, such as telecommunications, automotive, industrial, consumer electronics, and medical and is an ideal choice for many high-performance applications that require shielding protection. It is made with specially engineered, top-of-the-line materials to ensure quality and reliability. The contact arrays are designed to be easy to install, maintain, and are extremely durable. The contact system operates on the principle of providing a low-contact resistance while maintaining high shielding effectiveness. This is achieved through the combination of the fingerstock, mating gaskets, and the contacts.

Fingerstock

The fingerstock is typically composed of a highly resilient material such as an elastomer, and acts as an electrical barrier, preventing any current from passing between the contacts. The fingerstock effectively stops any energy created through the contact interface, providing maximum protection. Additionally, the geometrical structure of the fingerstock allows for very low contact resistance with both the contacts and the mating interface. This ensures that RFI and EMI signals remain high and are transmitted efficiently.

Gaskets

The gaskets provide a secure and reliable seal between the mating surfaces of the contact system. Gaskets act as the outer layer of protection, effectively blocking out any external electrical interference. The specially designed gaskets also help to reduce the contact resistance within the contact system, ensuring low electrical losses. Additionally, the gaskets serve to reinforce the contact system and reduce fatigue and wear.

Contacts

The contacts are the most essential component of the 8864-0110-72 contact system. The contacts are precision-engineered components that are designed to provide an electrical connection between the function provided by the fingerstock, gaskets and mating surface. The contacts are typically constructed with a high-conductivity material such as copper and/or silver, which provide superior shielding capability. Additionally, the contacts are typically fitted with gold-plating or other plating to further reduce any contact resistance and ensure a long-lasting electrical connection.

The 8864-0110-72 contact system is a powerful and reliable solution for protecting electrical equipment from RFI and EMI. Its combination of fingerstock, gaskets, and contacts provides superior performance while remaining easy to install and maintain. Furthermore, the use of high-grade materials ensures that the contact system is extremely durable and will provide many years of reliable service. As such, this contact system is an excellent choice for a wide range of high-performance applications.
