D-Sub Connectors: DBM21W1P1A9NA190K87 Application Field and Working Principle

D-Sub connectors are one of the most commonly used types ofelectrical connector on personal computers. The “D” stands for the shape ofthe connector housing. Generally, they are made of metal and used forconnecting computer monitor, printer, scanner, game console, etc., topower supplies, motherboards, and other electronic devices. D-Subconnectors can be found on the rear panels of many computer peripherals.The DBM21W1P1A9NA190K87 is the model number of a particular type ofD-sub connector. It is a 9-pin D-Sub connector that is commonly used onthe back of computer monitors. The connector features a molded femalehousing and 9 individually crimped pins. It is typically used toconnect the monitor to an analog video signal cable. It is important to note that D-sub connectors are typically availablein a variety of sizes and pin numbers. The DBM21W1P1A9NA190K87 is animportant part of the standard for computer video cabling, but there aremany other types of D-sub connectors available.The working principle of the DBM21W1P1A9NA190K87 connector is straightforward. The pins on the connector connect to the appropriate pins on thevideo cable. The metal shell of the connector serves to protect thecables from environmental elements and to provide mechanical stabilitywhile in use. The DBM21W1P1A9NA190K87 connector uses a standard 9-pin wiring pattern.The pin layout is designed to ensure that the video signal istransferred correctly from the source device to the monitor. The 9 pinsare arranged in a split pattern with 4 pins on one side and 5 pins onthe other. The signal pins are usually colored white, red, green, andblue, while the other pins can varies from device to device. The D-Sub connector is mainly used in the consumer electronicsindustry. It is a common type of connector used in television, audio, andvideo devices. It is also often used in computers, telecommunicationsdevices, laboratory equipment, and automated systems. D-Sub connectorsare frequently used to connect computer display cards to displays andto connect input devices such as keyboards, and mice to a computer.In conclusion, the DBM21W1P1A9NA190K87 is a type of D-Sub connector thatis commonly used to connect monitors to video signal cables. It ismade up of a female molded shell and 9 individually crimped pins. Ituses a standard 9-pin wiring pattern to ensure that the signals fromthe source device are correctly transferred to the monitor. The D-Subconnector is widely used in consumer electronics, telecommunicationsdevices, laboratory equipment, and automated systems.
