Rectangular connectors are an important component in many electronic devices, allowing for the transfer of data or current. The 57202-S51-20ULF is a versatile type of rectangular connector that serves a wide variety of applications. This article will cover the application field and working principle of the 57202-S51-20ULF.

Application Field
The 57202-S51-20ULF is a 2.00mm pitch, 14-position, single-row connector. Because of its low profile and slim design, it is suitable for high-density mounting, making it popular in several application areas including consumer electronics, communications, industrial, and automotive. It is also RoHS and REACH compliant, meaning it is considered environmentally safe.

The 57202-S51-20ULF is commonly used in applications such as smartphones, smart watches, Raspberry Pi boards, tablets, laptops, and wearable devices. It is also well-suited for the connection of sensors, power switches, and indicators. The connector itself is designed for both male and female interfaces.

Working Principle
The 57202-S51-20ULF is based on a friction locking system, which means a standard mechanical force is applied to ensure a secure connection. The connector and receptacle are locked together with a small latch, which goes into the mating channel and provides a tighter connection compared to other types of rectangular connectors. The latch also acts as a dust cover to protect the exposed contacts from dirt and dust.

The 57202-S51-20ULF offers several advantages over other types of rectangular connectors, including low insertion and extraction forces, a low profile that helps to reduce the overall size and weight, and a lower profile than other connectors when mounted. Furthermore, the use of a two-point contact system increases reliability.

The contact system of the 57202-S51-20ULF is composed of a flexible flat contact and two precision- machined contact points. The flexible flat contact is compliant and is designed to conform to mating PCBs. It also provides enhanced electrical connection to reduce surface resistance and increase the current-carrying capacity.

The two precision-machined contact points are used to guide the contact into the mating receptacle. This allows for easier and more reliable connections, as well as providing support for a variety of connection types, such as blind mated and tensioning stubs.

Finally, the 57202-S51-20ULF is designed to withstand vibration and shock, enabling reliable performance in harsh environment applications. It also offers ruggedness due to its high durability, which makes it ideal for vibration-sensitive products.

In summary, the 57201-S51-20ULF is a versatile type of rectangular connector that serves a wide variety of applications due to its low profile design, high current carrying capacity, and high reliability. It is well-suited for a range of consumer, industrial, and automotive applications, such as smartphones, smart watches, Raspberry Pi boards, tablets, laptops, and wearable devices.
