RFI and EMI - Contacts, Fingerstock and Gaskets

Category Introduction

Fingerstock and gasket contacts limit electromagnetic interference (EMI), also called radio-frequency interference (RFI) when in the radio frequency spectrum, that affect electrical circuits by electromagnetic induction, electrostatic coupling, or conduction. They are used where removable parts or doors attach to a chassis or enclosure, making them susceptible to EMI. Contacts are attached using adhesive, clips, hardware, solder, slotting or snap-in channels.
