RFI and EMI - Contacts, Fingerstock and Gaskets

A 4W12AB51G01800 is a type of RFID contact, fingerstock and gasket, used to contain, seal and protect RF signal and electromagnetic interference (EMI) from the outside. It typically consists of four components: contacts, fingerstocks, gaskets and interlock mechanisms.

The contact is a conductive material, such as plated steel, copper or aluminum. It provides the electrical connection between the RFID or EMI source and the outside environment. The contact is usually designed in two parts—the contact arm and the contact pin, and should be affixed to the board\'s edge connector to ensure a reliable connection.

Fingerstock is a metal material, typically made of aluminum or stainless steel, whose dimensions have been designed to fit the RFID or EMI components installed on the board. Each fingerstock component features different options—such as a threaded version, a pneumatic version, or an elastomeric version—to ensure a unique fit for each type of RFID or EMI application.

Gaskets are typically made of silicon rubber, plastic or metal, and are used to prevent moisture or dust from entering the enclosure. The gasket should form a tight seal, so that the internal temperature of the RFID or EMI component remains constant. It should also provide flexibility and cushioning, in order to limit shock or vibration in the RFID or EMI system.

The interlock mechanism is an electrical switch, used to lock and unlock the enclosure. For example, in a 4W12AB51G01800 unit, the interlock mechanism can be used to open the enclosure when a RFID or EMI component is installed.

The 4W12AB51G01800 is designed to meet a wide range of requirements for RFID and EMI application. It can provide reliable and secure contacts for RFID readers, antennas, and other components, and can prevent EMI leakage from entering or escaping from the enclosure. The interlock mechanism ensures a secure connection, while the gaskets protect the enclosure from dust and moisture. The fingerstock components can provide a custom fit for each RFID and EMI application, making it a versatile and cost-effective choice.
