Working Principle

The DM51157-12 has a metal connector body which serves as the ground connection between two contact sides. This is a typical design for D-Sub connectors. It provides mounting stability for the terminal and also ensures current conduction when mated with a contact hood. The contact hoods, which come in either a shrouded or non-shrouded variety, are made with metal reinforcement and feature a localized spring element that tensions all metal contacts at once for secure mating.The contacts of the DM51157-12 are available in two forms; male and female. Each contact is machined to ensure contact alignment and secure contact retention. Additionally, the contacts are also fitted with tin-plated contacts for enhanced corrosion protection. The gold-plating on the contacts provides excellent conductivity and greater levels of flexibility for data transmission applications.The DM51157-12 has been created to optimize performance by adding a series of features. It has a locking mechanism which provides a secure mating of the connector, and shields to reduce EMI emissions and protect cables from mechanical or chemical stress. The design also features preloaded springs for a reliable connection, along with mounting ears for stability and improved EMC performance.

Conclusion

The DM51157-12 is a highly robust, versatile and reliable D-shaped connector that is suitable for a variety of applications where extreme conditions are present. It features unique design components, such as the metal connector body, spring elements, and gold-plated contacts, that optimize performance and provide reliable connections. It is suitable for use in a multitude of industries from automotive to aerospace, and is particularly beneficial for harsh environment applications.
