57202-G51-17LF are a type of rectangular through hole connectors, which are also referred to as headers, and male pins. They provide the user with a reliable and easy-to-use connection for mating with compatible wires and other mating components such as box headers and mating sockets. Developed as part of Molex’s 57100 Series, these connectors are typically used for data protocols in applications which require low level, low resistance, and high cycle life. Let’s look at a few of the applications this connector can be used in and the working principle behind it.

Applications

The 57202-G51-17LF connector is used in a variety of applications, such as audio and video products, instrumentation, industrial control, and telecommunications. As they are designed to provide a reliable and efficient connection, they are commonly used for data protocols which require low level, low resistance, and high cycle life. Their ability to be used for data protocols makes them ideal for use in routers, repeaters, and other networking-based applications. As they are designed to provide a reliable connection which can withstand various environmental conditions, they are often used in harsh work environments, making them suitable for use in industrial, medical, and military applications.

Working Principle

The inteface provided by the 57202-G51-17LF connector is designed for compliance with the RS485 standard for data transfer. This means that they are capable of providing a balanced interface suitable for low level, low resistance, and long cycle life operation, as well as optimal signal integrity. This interface is provided by the use of individual conductors and terminal contacts which are soldered directly onto the printed circuit board (PCB). The terminal contacts are designed to ensure a reliable and secure connection between the connector and compatible mating components. An additional contact is placed between each contact to prevent electrical damage when mating or unmating the connector. The contact positioning and mechanical keying system are also designed to ensure accurate and secure mating between the connector and its intended target.

Additionally, the use of surface mount technology allows the 57202-G51-17LF connector to provide a superior level of design flexibility and board placement optimization. This allows for increased freedom in design, allowing it to be used in a variety of applications. The use of this technology also ensures greater reliability, longer cycle life, and improved resistance to mechanical shock.

In addition to the features discussed above, the hood and cable assembly available in the 57202-G51-17LF connector provide additional protection against environmental conditions. The cable assemblies are designed to protect against water and dust in applications where these can be a common issue. The hoods can also provide additional protection against electrostatic discharge, electromagnetic interference (EMI), radio frequency interference (RFI), and static overload, making them suitable for use in sensitive electronic applications.

Conclusion

The 57202-G51-17LF rectangular through hole connector is a great option for applications requiring reliable, low level, low resistance, and high cycle life. Its interface is designed for compliance with the RS485 standard for data transfer, making it suitable for use in routers, repeaters, and other networking-based applications. Additionally, its use of surface mount technology, hood and cable assemblies, and mechanical keying system ensure that it can provide reliable connections in a variety of applications, even under harsh environmental conditions. All these features make the 57202-G51-17LF an excellent choice for applications in audio and video products, instrumentation, industrial control, and telecommunications.
