It is an essential component in various electronic product structures where good shielding effect and low interference are required. This article will provide a detailed elucidation of the application field and the working principle of 4049PA51H01770 contact device.

Application Field

The application field of 4049PA51H01770 contact devices is broad and widely used in different areas. Generally, it is used in the following situations:

• Dropouts and mechanical shielding constructions for protection from EMI and RFI in electronic products;
• Mechanical shielding constructions in navigation equipments;
• Mechanical shielding structures in cellular radios;
• Medical instrument housings;
• Cooling pipes of heavy electronic systems;
• License plate frames of automobiles;
• Electronic music systems;
• Electronic flashguns in cameras.

Working Principle

The 4049PA51H01770 contact device is a comprehensive component that consists of contacts, fingerstocks, and gaskets. It works together to provide an effective shielding from any interference. When assembling, the contact is connected to the first sheet metal part and the fingerstock is connected to the second sheet metal part. The two parts will be fastened together by screws through the gasket. The gaskets are made of thermal-resistant silicone which has strong conductive properties. Upon tightening, the contact and the fingerstock will establish strong contact with each other and the gasket will protect them from the mechanical strength of the screws.

The contact and fingerstock are composed of a series of small “fingers” which are in direct contact with each other. When the two parts are pressed together, the fingers will form a continuous and strong contact. Each contact “finger” has a specific electrical resistance that helps to impede any electrical current from passing through the contact, creating an electrical shield which can protect the components from electromagnetic interference from outside sources.

The 4049PA51H01770 contact device is a self-ventilating metal system, allowing air to circulate inside and outside the shielding structure. The ventilation properties allow the device to remain relatively cool even under intensive operation. Due to its superior ventilation and high-temperature resistance properties, the 4049PA51H01770 can be widely used in heavy electronic systems with high ambient temperatures.

Conclusion

In conclusion, 4049PA51H01770 is a contact device with wide application field in various electronic product structures requiring good shielding effect and low interference. It is composed of contacts, fingerstocks and gaskets which work together to protect components from electromagnetic interference and provides ventilation for cooling the system in harsh environment. With its advanced technical properties, 4049PA51H01770 is an essential part in building shielding construction in various electronics.
