D-Sub connectors utilize a common mechanical design with multiple types of contact arrangements set into a robust metal shell. The DDMG-24C7P-J-K87 is a Threaded D-Sub connector that offers a typical connection suitable for external data transfer connections. It is a multipurpose connector manufactured by Amphenol and suitable for a wide range of industrial, communications and non-automotive applications including:

· Computers: The DDMG-24C7P-J-K87 is typically used for external connections to computer internal boards and to devices such as mice, keyboards and hard-drives.

· Telecommunications: The DDMG-24C7P-J-K87 is used in telecommunications, radio communication and networks such as LAN (Local Area Network) or WAN (Wide Area Network). It can also be used for a Voice over Internet Protocol (VoIP) or for video application.

· Industrial: The DDMG-24C7P-J-K87 connector is suitable for use in industrial automation systems including robotics, industrial control systems, and machine tools.

· Medical: The DDMG-24C7P-J-K87 is also utilized for medical instrumentation, especially for external data connections on heavier machinery such as X-ray or CT scanners.

The most common configuration of the DDMG-24C7P-J-K87 is a male connector with 24 contacts arranged in 7 positions spaced at 2.54 mm intervals. The current rating is set at 2.5 amps, suitable for digital applications. The Threaded version offers reliable, vibration/shock-resistant M3 threaded coupling, available in straight or 90 degree exit configurations.

The shell of the DDMG-24C7P-J-K87 is constructed of zinc-plated steel for robustness and corrosion resistance, while the contact blocks are constructed of phosphor bronze. The contact gold plating is typically 30 micro inches of gold over 50 micro inches of nickel, offering superior contact resistance. Additionally, Teflon insulators are used for improved insulation and resistance to abrasion.

The working principle of the DDMG-24C7P-J-K87 is based on the operation conducted by its contact blocks. DC voltage flows into the male connector while the female connector establishes the circuit. In a typical application, the current flow is from the male connector through the contact blocks and into the female connector. As a result, the voltage spike generated on the tip of the contact blocks produces a connection between the two counterparts and makes the circuit complete.

The contact blocks are the pivot of a number of mechanical and protective components but, most importantly, they complete the physical circuit. The contact blocks works by establishing a temporary connection between two circuits through a resilient abrasion-resistant surface. A release force applied to the male connector pins causes the force of the contact blocks to reduce until they are release from contact with the female connector block.

The overall design of the DDMG-24C7P-J-K87 achieves a robust and reliable connection even in the harshest industrial environments. It is a simple and cost-effective solution for data transfer requirements inside and outside a variety of applications.
