D-Sub Connectors: MDM-100SL2B-A174 Application Field and Working Principle

The D-Sub connector, or the MDM-100SL2B-A174 specifically, is a type of connector used in a variety of applications, from medical instruments to data and audio/visual equipment. This connector’s notable use of spring loaded and insulation displacement contacts ensures reliable connections and reduced manufacturing efforts. A brief overview of its application field and working principle will be given in this article.

Application Field

The MDM-100SL2B-A174 connectors are widely used in medical equipment, communications systems, audio and video equipment, and other electronic components. The most common use of a D-Sub connector is in PCs, where individual connections are created by soldering while several connections are mass-produced on PC boards. This type of connector is also an ideal choice for devices that require hot swapping or frequent assembly/disassembly, as well as vibration susceptible environments such as military and aerospace vehicles.

Working Principle

MDM-100SL2B-A174 connectors feature spring loaded contacts that are designed to provide reliable connections between the signal lines. These contacts are arranged into two different sizes, allowing for more complex wiring. The insulation displacement contacts (IDCs) are also featured in the D-Sub connectors, which make it easier to make secure connections with lower contact pressure. The contacts are also designed to ensure a strong electrical connection even after several cycles of assembly/disassembly.The contact pins on the MDM-100SL2B-A174 connector are gold plated and pre-tested to ensure that they are reliable and durable. This type of connector is also designed to provide a shield against electromagnetic interference (EMI). The contacts feature a positive latch mechanism to ensure that the connector stays secure during high frequency vibration and heavy Shock/Vibration applications.

Conclusion

The MDM-100SL2B-A174 connector is a reliable choice for applications that require frequent assembly/disassembly or vibration. The positive latching mechanism and insulation displacement contacts ensure sealing and connection stability in harsh environments. Furthermore, the gold-plated contacts are pre-tested to ensure that they will provide reliable signal transmission and EMI protection. All these features make the MDM-100SL2B-A174 connector an ideal choice for a variety of medical, communications, and audio/video equipment.
