RFI and EMI - Contacts, Fingerstock and Gaskets

The 4212PA51H04800 is a unique contact designed specifically for use in contactors, switches, and other electromechanical devices that require high current switching or transmission. This contact is designed to prevent the formation of arcs or sparks due to high impulse currents, while providing excellent mechanical and electrical properties for applications requiring high power switching. The contact is sealed against dust, moisture, and other contaminants to protect against unwanted debris or signal interference.

The 4212PA51H04800 contact has a unique construction that consists of three parts: the outer membrane, a finely-machined contact live, and an insulating medium. The live contact is made from silver and is soldered to the transition membrane in a one-piece process. The live contact is then allocated in the insulating medium to form a contact that is insulated from the surrounding environment. This construction ensures a solid and highly reliable electrical connection.

The contact is designed to operate at temperatures ranging from -20°C to +125°C, while offering an electrical range of 500mA to 3A and a maximum DC voltage of 1,500V. The contact is also corrosion resistant and has a long life expectancy due to its superior construction and materials.

Application Field and Working Principle

The 4212PA51H04800 contact is designed to be used in applications where high current impulse switching is required, such as contactors, switches, and other electromechanical devices. The contact is sealed against dust, moisture, and other contaminants to protect against unwanted debris or signal interference and is corrosion resistant. This contact is ideal for use in high-voltage circuits, such as industrial process controls, electrical power distribution, transportation, and other harsh environments.

The working principle of the 4212PA51H04800 contact is relatively simple. The live contact is soldered to the transition membrane in a one-piece process and is then enshrouded in the insulating medium. This construction ensures a solid and highly reliable electrical connection, and ensures that no arcs or spark can be formed due to the high-current switching. The contact is then able to transmit or switch currents efficiently without any unwanted signal interference or other issues.

The contact is also capable of resisting corrosion due to its superior construction and materials, which allows it to offer a long life expectancy in even the harshest of environments or processes. In addition, the contact is designed to operate at temperatures ranging from -20°C to +125°C, while offering an electrical range of 500mA to 3A and a maximum DC voltage of 1,500V. This ensures that the contact can be used in a wide variety of applications with a high degree of reliability and safety.
