The SFM-140-02-SM-D-A-N-K is an example of a popular header-and-socket configuration belonging to the rectangular connector family. In this article, its application field and working principle will be explored.

Application Field

The SFM-140-02-SM-D-A-N-K has a wide range of applications in various fields, being especially suitable for use in consumer electronics, automotive, industrial automation, medical equipment and other low power high speed signal applications, where high density connection is essential. It is capable of withstanding temperatures between -40℃ to +85℃ and a humidity of 60%. Use of this connector for high power, high voltage, or RF applications is not recommended.

Working Principle

The SFM-140-02-SM-D-A-N-K connector is designed with a female socket and a male header composed of a housing and terminal. The female socket is composed of insulation and non-metallic material and the male header is composed of insulating plastic cover and metal terminals. Contact pressure between the female socket and the male header is maintained by the male header terminal before and after mating. The connector is suitable for one-to-one mating and symmetrical adaptation for easy insertion and removal. The SFM-140-02-SM-D-A-N-K connector has two parts, the male header has 2 rows of 18 pcs, and the female socket in single row of 36 points. Both the male and female sockets are keyed. The contact resistance of the SFM-140-02-SM-D-A-N-K connector is low, typically -20mΩ, and the insulation resistance ≥1000MΩ.

The SFM-140-02-SM-D-A-N-K connector uses a combination of metal and plastic pieces to securely join components together. The basic parts of the connector include a male header which consists of a housing and various terminals, and a female socket with insulation material and non-metallic materials. The sockets and the male header are keyed, ensuring the correct orientation when mating. The contact pressure between the female socket and the male header is maintained by the male header terminal before and after mating, ensuring a secure, reliable connection. The connector also has low contact resistance, with a typical value of -20mΩ, and a high insulation resistance of ≥1000MΩ.

Conclusion

The SFM-140-02-SM-D-A-N-K is a versatile, reliable solution for connecting two electrical or electronic components with low power low voltage signals. It\'s wide range of applications from automotive, consumer electronics to industrial automation and medical equipment makes it an ideal choice for designers of all kinds of electronic products.
