1-640721-0

1-640721-0 is a type of electrical connector, composed of two or more electrically conducting elements—special power pins—coupled to each other to transmit electrical signals or power. It’s often used as part of a device or product assembly in the military, aerospace, automotive, industrial machinery, and more. Although used interchangeably with terminal strips, the two actually have different applications and functions.The 1-640721-0 family (available in both box and card types) is a range of high performance and cost-effective electrical connectors for the purpose of making and breaking electrical circuits. This type of connector offers more secure connections between two components, ensuring more reliable and consistent performance. They’re ideal for applications involving high currents or voltages, and can also be used with high frequency signals.

The application field of the 1-640721-0 depends on the specific model, but typically include power, grounding, RF, and sometimes shielding; though different models offer varying levels of protection and performance. Suitable applications include industrial machinery, military-aerospace, automotive, and more. The contacts within the connectors are used to make and break electrical circuits, making them perhaps the most versatile type of connector available.The working principle is a simple one. Two or more electrically conducting elements—usually metal pins—are mated together to form a connection. The contact points ensure that there is a reliable and consistent electrical connection between the two components. The pins themselves can be of two types: without any kind of insulation or with insulation of some kind.

The 1-640721-0 connectors are designed for the highest reliability and performance and can handle high current and voltage applications as well as varying levels of radiation. Their exceptionally high levels of electrical contact ensure strict quality control over both material selection and assembling. The contacts ensure minimal electrical resistance and offer superior electrical performance and longevity.

Moreover, in terms of design, these power connectors are compatible with a variety of industry-standard designs and are manufactured to suit a range of industry standards such as EN/IEC, ANSI/UL, and MIL-STD. The surface-mount version, 1-640721-0-M, is designed for mounting onto flat surfaces, and the box version includes a substrate to secure the pins directly on the PCB board.Overall, 1-640721-0 are reliable, secure, and efficient electrical connectors for a variety of applications. They’re perfect for both individual projects and large-scale manufacturing. Their design consideration, materials selection, and quality control ensure the highest reliability and performance even with high currents and voltages. They come in different sizes and versions to meet the specific requirements of any application.
