D-Sub Connectors

DBMP21W1SA197 application field and working principle

The DBMP21W1SA197 is a type of double-ended port interface connector more commonly known as a D-Sub Connector. It is used across a number of industries to provide reliable data communication between electronic devices. The most common uses include board-to-board and cable-to-board connectors in computers, laptops, printers and servers. It is also commonly found in industrial, security, consumer electronics, automotive, and other commercial applications, where data transmission needs to be reliable.

The DBMP21W1SA197 is designed to provide 25-pin parallel connections with two rows of high-density contacts. The contacts come in the form of five columns of five different shapes. This is done to prevent any mismatch or cross-connection. The terminal connector is installed using a press-fit or latch-lock system, making it easy to install, and preventing slippage or slackening of the wires.

The electrical connection is made using two rows of spring-metal contact terminals inside the connector housing. When two connectors are mated, the two rows of contact terminals are pushed together and electrically connected. The contact force is maintained by a shim between the terminals, which creates a constant contact tension. The constant contact tension ensures a reliable and durable connection, and prevents any corrosion or oxidation of the contact terminals.

The DBMP21W1SA197 connector is capable of handling a wide range of signal frequencies. It also offers an optimal combination of EMI shielding, vibration performance and durability to ensure reliable data transmission even in the harshest environments. The DBMP21W1SA197 connector also utilizes a flange-style construction for easy installation in tight spaces.

The DBMP21W1SA197 is an ideal application for board-to-board and cable-to-board connections where reliable and secure data transmission is a priority. Its wide range of contact formats, contact force, and EMI shielding make it a versatile and durable solution for a variety of industry applications.
