Rectangular connectors have been used in the electrical and electronics industries since the 1950s, and their use has continued to increase over the years. The 281739-2 series connectors are male/female pin headers designed for interconnect applications. This range of headers are widely used in audio, computer, telecommunications, automotive and other industrial applications because of their reliable electrical connections, low cost and small footprint.
The 281739-2 series headers feature a rectangular housing with an exterior made of plastic or metal with a contact system that consists of either two N-style male pins, or one N-style male and two N-style female pins. The contacts are located on one side of the housing and are secured using a locking screw, clips or some other attachment. This type of connector is fast and easy to connect and disconnect and is often used in applications that require frequent maintenance or repair.
The 281739-2 series connectors have a two-pin design that provides a reliable, low-resistance, low-loss electrical connection. The contacts are positioned so that they connect between the two pins when the connector is pushed in place, and the contacts have a low profile design to facilitate the connection. The contacts are made of copper alloy and are gold-plated to ensure a reliable connection. Additionally, each of the contact pins is insulated to prevent arcing and allow for safe, low-voltage operation.
The 281739-2 series connectors are designed for a wide range of applications, including those that require data or power communication. They are particularly well-suited for applications that require a reliable, low-profile connection in tight spaces. Examples of applications include computer motherboards, industrial control systems, telecommunications, and automotive electronics. Other applications include medical devices, circuit boards, LED lighting systems, and consumer electronics.
The working principle of the 281739-2 series connectors is relatively simple. The contact pins on one side of the connector are inserted into the mating component before being secured with a locking screw. When being used for data or power applications, the contacts on the socket are then connected to the required wires, and the mating connector is then pushed into the socket. The contact on the inner side of the connector then engages with the sockets contacts, completing the connection. In some circumstances, a special tool may be required to actuate the locking mechanism.
The 281739-2 series connectors are a reliable and inexpensive solution for interconnect applications in the electrical and electronics industries. Their two-pin design provides a low-resistance electrical connection that is fast and easy to install. The contacts are made of copper alloy with a gold-plating for reliability, and they are insulated to prevent arcing and allow for safe operation. The connectors are versatile and suitable for applications in a wide range of industries, including computer, telecommunications, automotive and medical.
