Rectangular connectors - headers, specialty pin, such as 380-40-139-00-001000 are a type of connector typically used in electronic circuits. They are designed to give electrical connection between two or more points, while preventing interference between different circuits. These connectors are classified by their size, shape, number of pins and contact style.

380-40-139-00-001000 is among one the most common types of rectangular headers. This type of rectangular connector has 4-40 pins arranged in five parallel rows with a pitch of 0.025” per pin. It is a right-angle, snap-in, surface mount connector, with the pins alternating in length to provide better stability, when soldered. The connector includes three power-way and two signal-way rows with copper on the power way row for improved electrical performance.

These connectors are mainly used for protoyping and tests and are ideal for connecting printed circuit boards (PCBs) and quick prototyping. It is also common to find them used in test and measurement equipment, electronic and communication equipments, power mixing boards and automotive engines.

The working principle of these connectors is relatively simple. When used as receptacles, they are plugged into mating-probes and a latching mechanism keeps them firmly in place. As wih other rectangular headers, 380-40-139-00-001000 are made of light-tolerant materials, such as fiber-glass reinforced with polyamide, or polyester with polyamide, which helps them withstand the test of time and heavy use.

The contacts in this type of header are often made of electro-plated copper and tin alloy, which offers good conductivity and prevents arcing. The contacts may also be gold-plated, ensuring a high-quality connection with low contact resistance.

These rectangular connectors are easy to install and provide a reliable connection for a variety of applications. They are also highly resistant to both mechanical and electrical shock, making them a great option for applications with tight and limited space. Furthermore, this type of connector provides high signal integrity and can transmit high frequencies with minimal distortion and interference.

In conclusion, 380-40-139-00-001000 is a type of rectangular connector specifically designed for applications with tight and limited space. It offers good conductivity, reliable connection and high signal integrity to ensure a trouble-free operation. It features four-40 pins arranged in five parallel rows with a pitch of 0.025” per pin, and is made of light-tolerant materials such as fiber-glass reinforced with polyamide, or polyester with polyamide. Its contacts may be electro-plated copper and tin alloy or gold-plated, as required.
