57202-S52-03A

Rectangular Connectors - Headers, Male Pins form an important part of every electronic device and wiring system. They are used to connect low voltage circuits, provide power, transfer signals, and deliver data. 57202-S52-03A is one type of headers with male pins that is usually provided as a two-piece molded connector assembly with polarizing pegs and side entry sockets. It is a great choice in applications which require a rugged, flexible, and cost-effective solution.

Application Field

57202-S52-03A is commonly used in a wide range of industries, including automotive, CCTV, lighting, medical, telecommunications, transportation, and home automation. It is favourable in applications requiring higher power handling capacity such as bus bar termination, power distribution, and ground wiring. Its simple and flexible configuration enable it to perform well in situations such as space savings, board-to-wire connection, cable-to-board connection, and multiple-connector assemblies.

Working Principle

57202-S52-03A headers include a contact pin that protrudes from the sides of the housing and is typically spring-loaded to make contact when mated. They require a female connector, such as 57202-D52-03A, on either side to complete the connection and to achieve electrical continuity between the two contacts. The contact pins are either formed flat or molded into a base to provide polarization and ensure proper mating of the headers. The assembled pin and its base provide strain relief and prevent shorts by preventing adjacent contact pins from touching each other.

57202-S52-03A headers also feature an integrated housing made from thermoplastic, high temperature polyamide (PA) or liquid crystal polymer (LCP). The housing has two open sided slots with a central wall that provides mechanical protection and mates with mating headers that have flat contacts. The two ribs on the housing allow it to be easily installed in standard printed circuit boards. The contacts are usually gold-plated, providing better electrical performance by reducing contact resistance, improving reliability, and making the contacts more corrosion resistant.

In conclusion, 57202-S52-03A is a highly reliable and robust connector system. It is suitable for a variety of applications due to its simple assembly, robust construction, and superior polarization features. It can be used in a wide range of industries, offering improved power handling capacity, board-to-wire connections, space savings, and reliable performance.
