Introduction

A 929838-04-03-RK is a specialized rectangular connector for certain applications, and is part of the header family of connectors. Headers, male pins and connectors are used in a variety of applications across industry — from connecting basic electronic circuits in OEM applications such as cell phones and computers to connecting consumer products, test and measurement equipment, medical instruments, and even heavy machinery and manufacturing systems.

Application Field of 929838-04-03-RK

The 929838-04-03-RK header and male pins are used to transfer signals and power between two components, such as printed circuit boards (PCBs). The connector features two rows which are numbered and exit through the sides of the housing. It is a low, shielded version, making it a good choice for applications where short-circuit protection is needed. Given its small profile and wide range of optional mounting options, this connector is widely used in industrial panels, racks and boards.Because the 929838-04-03-RK has a limited number of pins, it is used for simple connections such as one-way signal traveling or power feed, usually for application in low speed digital devices, testing and monitoring equipment. It is also typically used for applications that require flexibility, as it can be mounted directly onto a PCB using standard through-hole or surface-mount technology. In addition, due to its small footprint, it can be used in tight packaging and interference environments such as robotics, injection molding, process controls and motion control systems.

Working Principle of 929838-04-03-RK

Each connector consists of two parts — the housing, which keeps the pins securely in place, and the terminals, which are inserted into the housing. The terminals are made of metal, usually brass, steel or copper, and can be copper-plated or gold-plated for better electrical connections. The two parts are connected using an intuitive latch system, ensuring secure mating of the connector. Once securely groomed together, these two pieces need to be soldered to the PCBs, which require appropriately sized connection holes. The 929838-04-03-RK has two types of terminals — standard female terminals and crimp-style terminals.The crimp-style terminals are connected to the wire via a terminal blade or a spliced pigtail, and the connection is locked into place when the terminal is closed. Crimping the terminals is usually done by hand using a crimping tool, and is sometimes also done on automated machines. Once crimped, the connector’s contacts are completely enclosed by its housing.For reliable signals transmission and data integrity, the 929838-04-03-RK needs to be fitted with appropriate covers and shields. Covers ensure that the connectors are protected from external elements such as dust, moisture and shock, and shields minimizes electrical interference. The shield is usually fitted to the outside of the terminal; some more secure-fitting shields are also available and can be inserted into the connector.

Conclusion

The 929838-04-03-RK is a lightweight and low profile rectangular connector, designed for applications where robustness, reliability and flexibility are important. The connector is used for simple connection between two components. It has two rows of terminals — standard female pin ends and crimp style ends — and is usually shielded to ensure reliable signals transmission. It can be used for a variety of applications, including industrial panels, consumer products, medical instruments and even computer and cell phone applications.
