MDM-21PBSL56-A174

MDM-21PBSL56-A174 is a type of D-Sub Connectors with specific application field and working principle. It is a type of full-size, economical D-Sub miniature connectors and are widely used for computer and communications connections. Connectors of this type have a low profile, durable plastic body, rugged construction, reliability and affordability.

Application Field

The MDM-21PBSL56-A174 connectors are primarily used for applications where a male and female connector need to be quickly and securely connected. These connectors are useful in any environment with frequent connections and disconnections and for applications where tight electrical conduction is required. These connectors can be seen in the computer industry where they are used to connect motherboards and expansion slots of various kinds, such as serial and parallel ports. They are also used in communication systems and instrumentation. The installation procedure is very simple and requires only a few tools.

Working Principle

The MDM-21PBSL56-A174 connectors have a reliable mechanical and electrical connection due to its two-piece connection system. The two-piece connection system consists of a complementary male and female D-sub connectors which when secured together form a secure connection. Each connector has a insulating front shell with metal shield, multiple pins and sockets at the terminal points and a rear metal cable clamp. The pins on the male side are arranged in a pattern that matches the space of the female connector sockets. When the male and female halves are separated, a male and female terminal section expand or collapse to ensure a secure connection when the two halves are mated together. The positional accuracy of this two-piece connection provides a very stable EMI shielding capability without the need for additional materials such as EMI absorbers or double shielding.

The MDM-21PBSL56-A174 connector also has an optional locking mechanism which consists of a main operating key and a set of individual keys and claws that secure the main body of the connector. This locking mechanism ensures that the connection is secure and does not become loose when the user plugs or unplugs the connectors. The locking mechanism is also used to prevent accidental disconnections.

Overall, theMDM-21PBSL56-A174 connector has a flexible mechanical and electrical connection, which makes it suitable for a variety of applications and it is also cost-effective.
