DBM5P5S1A9NA191 Datasheet/PDFD-Sub Connectors
D-sub connectors are a type of electromechanical connectors with a specially designed shrouding which provides a robust mechanical connection and EMI protection. They are highly customizable and typically feature either male or female inserts, multiple connection types, and various numbers of pins, depending on the application.
DBM5P5S1A9NA191 Application Field and Working Principle
The DBM5P5S1A9NA191, a male connector, is designed for use in harsh industrial and military/aerospace applications. It is designed to operate under extreme environmental conditions, such as high heat, shocks, and vibration, and features a robust die-cast metal shell that provides excellent environmental protection. The connector supports both signal and power connections, and is made of gold-plated pins for reliable low-resistance electrical connection. The D-Sub connector features a high-voltage rating of up to 12 V, a current rating of up to 1A, and an operating temperature range of -55 °C to 125 °C.
In terms of working principle, the D-Sub connectors feature two mating parts that are secured using crimp technology. One mating half, called a male connector, features pins or sockets on the outside surface which mate with the corresponding pins or sockets on the other mating half, called the female connector. As the two mating halves are brought together, the pins/sockets on the male connector engage with their counterparts on the female connector and the connectors then "snap" together, securing them in place. Once locked in place, the two connectors provide a reliable electrical connection between the two devices.
In many cases, the D-Sub connectors are equipped with a locking mechanism—such as a thumbscrew or bayonet-style—that further enhances the connectors’ strength and durability. The locking mechanism serves two main functions. It firstly ensures that the two mating connectors remain securely mated once connected; and secondly it helps protect the pins/sockets from being damaged due to vibration or misalignment of the mating halves.
In conclusion, the DBM5P5S1A9NA191 is an ideal solution for industrial and military/aerospace applications that require reliable connections and a robust, die-cast metal shell for environmental protection. Its gold-plated pins provide a reliable, low-resistance electrical connection, and a locking mechanism such as a thumbscrew or bayonet-style ensures that the mating connectors remain securely mated.
