SFML-140-01-S-D-LC

Rectangular Connectors – Headers, Receptacles, Female Sockets are used in a variety of applications. In this article, we will discuss the SFML-140-01-S-D-LC connector’s key features and application field, as well as its working principle.

Overview of the SFML-140-01-S-D-LC connector

The SFML-140-01-S-D-LC is a rectangular plug-in connector from Rosenberger’s OCC (Optimized Cost & Control) family. It is a 40-pin female socket connector with D-Sub contact on one side and double locking latch clips on the other. It has an incredible specifications: a contact resistance of 10 mΩ, a dielectric withstanding voltage of 500 VAC, an insulation resistance of 500 MΩ, and a rated current of 4A.

The D-Sub contact is shaped in an especially designed way, allowing for space saving product design. Also, the double latch clip securely locks the plug-in connector in its insert, further guaranteeing reliability in high vibration applications.

Application fields

The SFML-140-01-S-D-LC connector is contact certified and suitable for various applications. It is most commonly used in telecom and datacom, computer systems, industrial automation, and medical applications.

It is perfectly suited for applications where space is confined, as the D-Sub contact type ensures better space saving design options. OCC connections are also a great choice when it comes to transmitting high power signals, as they allow for improved signal integrity when compared to wire-to-board solutions. The SFML-140-01-S-D-LC connector also provides high reliability with its double latch clip lock, making it a good fit for rugged industrial applications.

Working principle

The SFML-140-01-S-D-LC connector enables mated connections between two appliances. It consists of a plug-in part on one side, with a female socket on the other. On the plug-in part, there are 40 female skirt wires with gold contacts. When the plug-in part is inserted into the female socket, the mattes contact with the female skirt wires providing a secure connection.

On both sides of the plug-in part, there are locking mechanisms made from metal, designed to keep the plug-in part in its insert. The locking mechanism is made with double-latch clips providing an extra secure connection and helping against vibrations.

Conclusion

The SFML-140-01-S-D-LC connector is a multi-functional part that belongs to Rosenberger’s OCC family. It provides excellent data transmission and reliable connection in a variety of application fields such as telecom and datacom, computer systems, industrial automation, and medical applications, thus providing cost and space savings. The plug-in part mates with the female socket providing 40 reliable contact points, and the double latch clip provides reliable locking and protection against vibrations.
