SFM-120-T2-L-S-A

Rectangular Connectors – Headers, Receptacles, Female Sockets

Rectangular connectors or pins, headers, receptacles, and female sockets are integral components of modern electronic circuits. As such, they are used in a wide range of applications in industrial, commercial and consumer electronics.

The specific type of connector designated as SFM-120-T2-L-S-A belongs to the family of electrical connectors which use a rectangular contact configuration and are designed to mate with another connector of the same type. The SFM-120-T2-L-S-A is a two-position, straight, surface mount, lead-free, female socket connector. It is 0.062 inches and has two pins which are spaced a 0.2 inch apart.

Application Field

The SFM-120-T2-L-S-A is typically used as a connector in printed circuit board (PCB) designs requiring a small, high-density connection. It is frequently found in miniaturized electronics, like cell phones, PDAs and other hand-held electronics as well as more specialized industrial or commercial applications where space is at a premium. The SFM-120-T2-L-S-A may also be found on older power supplies, keyboards and mouse devices.

Working Principle

The SFM-120-T2-L-S-A operates on principles similar to other rectangular connectors. When the connector is mated to an appropriate mating connector, electrical contact is achieved through the use of spring-loaded contact pins which mate with corresponding female contacts. This contact is further secured against vibration and mechanical shock through the action of crimping strips.

In order to ensure optimal electrical contact, it is necessary to ensure proper alignment of the male and female ends during mating. Proper alignment is achieved through the use of locating keys and bosses on the female connector. Additionally, metal strain reliefs ensure that the electrical contacts are positioned properly for optimal contact.

Finally, the contact pins within the SFM-120-T2-L-S-A are designed to achieve a current rating of 2A @125V AC or DC, depending upon the specific construction material used in the manufacturing process.

Conclusion

The SFM-120-T2-L-S-A connector is an invaluable and versatile component in the world of electronic circuits. Its high-density design, current rating, and the ease of manufacturing make it an ideal choice for applications where space is a premium and maximum current draw is necessary.
