D-Sub connectors are designed to provide a connection to D-shaped metal shells that are often referred to as D-subs. These connectors serve a wide variety of applications, and the 747908-2 model is no exception. This particular connector is a 15-position miniature plug, designed to match the corresponding receptacle (747918-2). Let us take a closer look at the 747908-2 application field and working principle.

Application Field

The 747908-2 is a versatile connector which is designed for quality performance in a variety of settings. The 15-position miniature plug is widely used in communications, aerospace, industrial controls, medical electronics, military and other specialized applications. It is commonly used to connect wires to circuit boards, insulation displacing connectors, ribbon cables and other wire harness assemblies in multiple applications. It is also designed for high voltage and high frequency with a reliable and robust connection.

Working Principle

The 747908-2 has a standard design for D-sub connectors. The 15-position miniature plug has a single row design, with 2mm pitch between contacts. The connector has a plunge-and-lock feature so that the plug can easily be mated and locked into place without the use of any additional tool. The contact pins for the plug are machined of co-axial brass material, ensuring a secure connection. The contacts are plated with a tin-lead alloy coating to help reduce wear and abrasion.

The contacts are held in place by a plastic housing which is designed to be highly durable. The plastic housing is designed to fit securely and perfectly into the receptacle with the use of a screw-lock feature. This lock feature ensures that the connection is secure and prevents any unwanted movement of the miniature plug.

The electrical interface is enhanced by the use of a unique contact seal design which is fitted to the connector from the factory. This contact seal ensures that the connection is reliable and maintains quality performance even in harsh environments. The connector is designed to meet IP68 rating, and features a minimum of 500 mating cycles.

Conclusion

The 747908-2 D-Sub connector is designed to provide a reliable connection between electronic components and devices. The 15-position miniature plug is versatile, secure and reliable, making it suitable for a variety of applications. With its plunge-and-lock feature, contact seal design and screw-lock mechanism, the 747908-2 is an excellent choice for any electronic circuit.
