Introduction
Rectangular connectors, also known as header pins or male pins, are commonly used for modern electronic connections. Headers are typically used to terminate single-pin connections between boards, displays, and other pieces of electronic hardware. 3-1871056-2 is a specific type of rectangular connector designed to provide users with strong, reliable connections. In this article, we will discuss the application field and working principle of 3-1871056-2 rectangular connectors.

Applications
3-1871056-2 rectangular connectors are commonly used within a wide variety of electronic applications, including but not limited to: aviation, automotive, medical devices, consumer electronics, and telecommunications. Specifically, they are often used to establish a connection between boards, displays, and other pieces of electronic hardware via a single-pin connection. This type of connector allows for transmission lines to be classified into two main categories: high-frequency and low-frequency, which are suitable for applications that require a high level of reliability, in addition to being small and lightweight. Additionally, 3-1871056-2 rectangular connectors do not need to be soldered – they can be used without the need for additional wiring devices.

Working Principle
The 3-1871056-2 connector is a single-pin rectangular connector with a metal casing. This particular type of connector uses a locking mechanism, so that once the connection has been established, it cannot be released unless it is specifically unlocked. Additionally, this type of connector uses a screw-lock system, meaning that the connection can only be locked and unlocked when the appropriate screw has been turned. This prevents accidental disconnection. In terms of electrical connections, 3-1871056-2 rectangular connectors typically carry a voltage of up to 30 volts and can support a current of up to 2 amps.

Conclusion
The 3-1871056-2 rectangular connector is a type of header pin or male pin connector that is commonly used for modern electronic connections. It is a single-pin connector with a metal casing that utilizes a locking mechanism and a screw-lock system for reliable connections. 3-1871056-2 connectors are suitable for applications such as aviation, automotive, medical devices, consumer electronics, and telecommunications, and have a voltage rating of up to 30 volts and a current rating of up to 2 amps.
