Rectangular Connectors- Headers, Receptacles, Female Sockets

Circular connectors offer many advantages over rectangular connectors in terms of ease-of-use and safety. Although circular connectors have a wide range of applications, for some applications rectangular connectors are the best or only viable option.

In this article, we will take a look at one specific rectangular connector type, and in particular the specific model SDL-120-TT-12. We will examine its application field and working principle.

Application Field

The SDL-120-TT-12 is a type of Industrial interconnect, used in many fields such as aerospace, automotive, industrial automation, and medical. It is designed with a hard shell for added durability, and is RoHS compliant.

The SDL-120-TT-12 is used in electronic devices such as video transfer systems, drives, motor controllers, electronic valves, servo drives and other controllers and interfaces. It is also suitable for applications such as data transmission, power distribution and ground loop isolation.

Working Principle

The SDL-120-TT-12 comprises of two components, a header and receptacle. The header is inserted into the receptacle and secured with screws. This ensures a safe and reliable connection. The connector provides a grid of 12 zones, each with a recessed contact point. Once connected, the contacts provide electrical connections required for the device.

The SDL-120-TT-12 features bi-directional cable coupling, which makes it easier to install and provides redundancy in the case of a single point distribution failure. The connector also has polarized contact points, which helps prevent incorrect installation by ensuring they are installed the right way round. The connector also has a low mass design which allows for easy installation and efficient performance in the field.

The connector is designed to meet the required current rating and voltage rating, and features a dielectric strength of 500V/0.35A and a nominal insulation resistance of 5000mohms.

Conclusion

The SDL-120-TT-12 is an Industrial connector designed for applications where reliability and high performance are required. Its features include a hard shell, bi-directional cable coupling, polarized contact points, low mass design, and dielectric strength. Its applications include aerospace, automotive, industrial automation, medical, and many others.

The connector is designed to meet the required current rating and voltage rating, and features a dielectric strength of 500V/0.35A and a nominal insulation resistance of 5000mohms, making it a safe and reliable connector for many applications.
