D-Sub connectors are a widely used form of electrical connectors that have been extremely popular for many applications for a variety of reasons. One such type of D-Sub connectors is the DB-25P-NR. These are shielded D-Sub connectors that are primarily used for mini-computers, terminal networks, medical equipment, data communication, vending machines, industrial control, automotive, and other similar applications. This type of D-Sub connector is often used in combination with an RJ-45 connector to provide a reliable electrical connection for the purpose of data transfer.

To fully understand the DB-25P-NR connector, it is important to look at the overall construction of a typical version of this connector. The shell of a DB-25P-NR connector is constructed of zinc alloy, which provides strength to the connector while still allowing flexibility. Inside the shell is an array of 25 pins, each of which is soldered to a terminal block. The terminal block is in turn attached to the wiring harness, which connects to the electrical components that the DB-25P-NR is intended to interface with.

The DB-25P-NR connector utilizes both firewire and shielded cable, providing superior shielding performance. It also features a rated voltage of 250 volts, a rated current of 10 amperes, and a maximum contact resistance of 10 milliohms. This combination of features allows the DB-25P-NR to handle up to 10 amperes of current, withstand high voltage and current levels, and provide excellent resistance against electromagnetic interference.

The DB-25P-NR connector also features a two-piece shell design, which enables it to easily accommodate lugs as needed. This allows the connector to be used in a variety of different applications and provides additional flexibility for different mounting options. The connector can also be used in a variety of high temperature and cold temperature applications due to its temperature range rating of -65 to +350 degrees Fahrenheit.

To further explain the applications and working principles of the DB-25P-NR connector, it is necessary to look at the engineering of this device. Each of the 25 pins on the DB-25P-NR connector is an electrical conductor that connects two separate metal objects (commonly referred to as pins) together. The connection of these pins creates a physical connection between two components, while also providing a conductive pathway for an electrical current to travel. In this way, the DB-25P-NR allows for a continuous electrical connection between two separate components.

The DB-25P-NR connector is also used as an extension of the RJ-45 connections in order to provide additional protection from electromagnetic interference. The connector is rated to offer up to 10KΩ of protection from interference, and is capable of providing a reliable connection in even the most demanding electrical environments. This makes the DB-25P-NR ideal for use in harsh electronic applications, such as industrial or automotive settings, where high voltage power is required.

In conclusion, the DB-25P-NR connector is an incredibly versatile and reliable form of D-Sub connectors that can be used for a wide range of applications. Its two-piece shell design, shielded cable and firewire connections, and its rated voltage and current capabilities make it an ideal choice for various industrial and automotive applications where high voltage power is necessary. Furthermore, its internal conductors provide a continuous connection between two components, and its shielding ensures that interference does not interfere with the signal.
