A rectangular connector header is a method of connecting electronic components, circuit boards or cables with a plug. STMM-125-02-FM-D is a two-row, male pin type, rectangular connector header manufactured by E-Switch, an industry-leading supplier of electronic components. Characterized by two rows of contacts, interconnected in a box-shaped mating pair with two mounting holes, STMM-125-02-FM-D offers a wide range of application fields and is commonly used in the electronics industry for the reliable and secure transfer of high-speed data.

The header system can be soldered to the PCB allowing it to receive energy from a power source via a power cable, connecting wires from multiple circuit boards in a variety of settings, connecting connector cables to a PCB, connecting a card-edge or cable-edge connector to a board, and finally connecting wires to a sensor. Moreover, the main application fields include consumer electronics, electric automotive, medical equipment, audio-visual equipment, and industrial automation.

The working principle of the STMM-125-02-FM-D is based on the idea of a plug-locking mechanism, which is accomplished through the use of locking pins on both the header and the plug. These locking pins are designed to provide a secure connection between the header and the plug and prevent the cable from being easily disconnected. Additionally, the headers incorporate a patented arc-action design and a gold-plated/tin-plated metal contact surface, which ensures reliable data transfer and excellent electrical conductivity.

In terms of the basic components, STMM-125-02-FM-D is constructed of two separate housing units: a header and a plug. The header consists of two rows of contacts arranged in a rectangular configuration and mounted on two mounting holes. On the other end, the plug contains locking pins and a slot which correspond to the positions of the contacts on the header. In order to ensure an electrical contact between the header and the plug, the connector relies on a spring-loaded plunger pin, which is also known as a female pin contact. Finally, the pins are plated with a layer of gold or tin for better corrosion resistance and reliable electrical contact.

The STMM-125-02-FM-D is a reliable and secure method of connecting components, circuit boards or cables in a variety of settings. Thanks to its unique design and features, the header is suitable for a wide range of electronic applications. In addition, its robust construction, durable materials and contact plating ensure reliable data transfer and excellent electrical conductivity.
