Rectangular Connectors, also known as ‘headers’, male pins and sockets, are becoming increasingly popular in the industrial, aerospace, automotive and communications sectors due to their reliability, robustness and ability to fit seamlessly into tight spaces. A popular example of this type of connector is the 79257-140HLF. In this article we will provide an overview of the application fields and working principle of this area of electrical connection technology.

The 79257-140HLF Rectangular Connector is primarily used in automotive wiring, as it is able to withstand the high temperatures and vibrations of automotive-engines. Its robust design is also useful in harnessing, telecommunications, and medical-imaging equipment, as well as for other industrial applications.

The 79257-140HLF is a single-wire male pin connector. It has an environmentally sealed plastic actuator, is highly resistant to impact and moisture, and has a high dielectric strength. The connector has an overall length of 51.050 mm and features 6.00 mm pitch mating cavities. It has an external shell made of thermoset plastic and internal shell of thermoplastic. The 79257-140HLF’s chamfered leads and ribs as well as its mating steps, enabling reliable connections and preventing shorts.

The 79257-140HLF’s contact-pins are made of copper and plated with palladium for increased corrosion resistance, and feature gold plating on the mating cavities surface to secure lock-ins and excellent EMI protection. The pin header is also rated to a temperature range of –40°C to 105°C, enabling it to function in a wide range of temperatures. The connector is also available with a male contact secured with a lock washer for extra security and utilizes easy-to-use snap-fit and wire wrap mounting.

The 79257-140HLF’s working principle is simple yet effective. Its contact-pins are designed to complete an electrical connection by plugging into the female connector. The contact-pins then make a physical connection with the circuit board, allowing for the electrical connection of the circuit. The plastic actuator helps ensure that a tight seal is maintained between the pins and the circuit board, preventing the flow of electricity.

In conclusion, the 79257-140HLF Rectangular Connector is a reliable and robust connector that is suitable for use in various industrial, aerospace, automotive and telecommunications applications. Its strong construction and reliable contact-pins make it an excellent choice for reliable and efficient electrical connection.
