Introduction: D-Sub connectors, also known as DB connectors, are used in many electrical and electronic applications. MDM-25SL2B-A174 is a D-Sub connector that is commonly used for shielded connections in high speed serial, RS-232, and other high speed communications applications. This article will discuss the application field and working principle of this connector.

Application Field: The MDM-25SL2B-A174 D-sub connector is mainly used in applications requiring shielded connections in high speed serial and RS-232 communications applications. It is compatible with many PC motherboards, as well as various custom configurations. It is also widely used in other applications such as medical devices, industrial equipment, military systems, or telecommunications. The connector is designed with compact size and robust construction, making it ideal for applications requiring high reliability. It has a contact arrangement of 2 rows by 25 pins, with each row having 13 short pins and 12 long pins. The contacts are gold plated, offering low contact resistance and excellent signal transmission.

Working Principle: The MDM-25SL2B-A174 D-Sub connector is a shielded connection type, meaning the outer shell contains a metallic shield designed to reduce electrical and electromagnetic interference. This shield is made from a variety of conductive materials such as copper, aluminum, or stainless steel. The contacts are plated with gold to ensure good contact between the two components and reduce electrical resistance. These contacts are connected to a PCB (Printed Circuit Board) through contacts known as PCB tails. The PCB tails enable the contacts to be soldered to the board. The inner contacts are connected to the board via contacts known as dielectrics or insulation displacement connectors. These contacts can be used to connect the incoming signals from the integrated circuit, the control panel, and the output devices.

Features: The main features of MDM-25SL2B-A174 D-sub connector include its compact size, robust construction, high reliability, low contact resistance, and good signal transmission. It also has a high power rating, allowing it to be used in applications that require high throughput. The connector is designed with industry standard dimensions, making it easy to interface with other D-sub connectors. The contacts are made of gold plated for excellent signal transmission and low contact resistance. The connector also features a locking mechanism for secure connection. In addition, the connector is designed with durable materials, making it ideal for harsh environments.

Conclusion: The MDM-25SL2B-A174 D-Sub Connector is a reliable and cost effective solution for shielded connections in high speed serial, RS-232, and other high speed communications applications. It is designed with compact size and robust construction, making it ideal for applications requiring high reliability. The connector features a locking mechanism and gold plated contacts for excellent signal transmission and low contact resistance.
