Rectangular connectors are essential components in electronic systems that allow two circuits to be interconnected. Headers, receptacles, and female sockets are three types of rectangular connectors often used in power and signal applications. In this article, we will take a look at a specific rectangular connector - 399-91-121-10-003000 - and discuss its application field and working principle.

A 399-91-121-10-003000 connector is a type of rectangular plug and receptacle connector with a 2-row, 9 pin configuration. It is typically used in low-voltage power and signal applications. In terms of voltage, it can handle up to 500 V. It is also UL and CSA certified and meets RoHS and REACH standards.

The pinout configuration of the 399-91-121-10-003000 connector consists of two rows of nine pins. The first row has four pins in the center and the second row has five pins in the center. The pin assignment is as follows:

• Row 1: 1, 2, 3, 4
• Row 2: 5, 6, 7, 8, 9

The 399-91-121-10-003000 connector is used mainly for power and signal applications. It can be used for a variety of purposes, including connecting two circuits, interconnecting two power sources, distributing power to different components, and transferring signals between circuits. In addition, it is also commonly found in automotive, communication, and consumer electronics applications.

In terms of working principles, a 399-91-121-10-003000 connector works by making electrical contact between its pins and the corresponding terminals of the mating connector. As a rectangular plug and receptacle connector, the 399-91-121-10-003000 connects to other components using a specific mating pattern (depending on the pin-out configuration) to ensure a secure connection. The connection is then secured using a screw, which is tightened down to make sure the two connectors are secured together.

In terms of construction, the 399-91-121-10-003000 connector is made of high-strength plastic and is designed for longevity and reliability. To ensure a secure connection, the pins are plated with gold or tin-plated copper, which ensures a reliable electrical connection between the two connectors. In terms of durability, the 399-91-121-10-003000 can withstand temperatures ranging from -25 degrees Celsius to +105 degrees Celsius.

In conclusion, the 399-91-121-10-003000 connector is a type of rectangular plug and receptacle connector with a 2-row, 9 pin configuration. It is mainly used for power and signal applications, such as connecting two circuits, interconnecting two power sources, distributing power to different components, and transferring signals between circuits. The connector is made of high-strength plastic and is designed for longevity and reliability. It can also withstand temperatures ranging from -25 degrees Celsius to +105 degrees Celsius.
