D-Sub Connectors

D-Sub connectors, also known as D-Subminiature connectors, are electronic connectors commonly used for computer and peripheral connections, as well as other industrial applications. The most common form is the D-Sub 15-pin connector, but several other sizes are available, ranging from 4–100 pins. D-Sub connectors come in different configurations and genders, with male or female plugs in several combinations.

DBMR9W4S Application Field and Working Principle

The DBMR9W4S is a 15-pin right angle male D-Sub connector manufactured by Hirose Electric Co. Ltd., a Japanese electronics company. This connector is designed for use in applications where space is at a premium, as it has a total height of 9.2 mm. It is mainly used for data signals, as it is often found in the back panels of industrial and office equipment such as computers, monitors, printers, and scanners.

The DBMR9W4S features two rows of 15 parallel metallic pins, each of which is 1 mm thick. The pins are designed to make electrical contact when mated with a female connector. To ensure a secure and reliable connection, the pins are coated with a nickel plating, and the plastic body is held together with special keyed metal screws.

The connector also features a metal shell, which helps to provide mechanical strength and environmental protection. The shell is made of zinc-plated iron or stainless steel, depending on the application. The shell is designed to allow the connector to be mounted easily onto a panel, and also prevents EMI interference from entering the system.

The DBMR9W4S has a current rating of 1A, and a voltage rating of 70V. It has a temperature range from -30°C to +105°C, and an operational life of up to 500 mating cycles. This connector is compliant with the IEC 60603-2 standards, as well as the UL 94V-2 flammability standards.

Overall, the DBMR9W4S is an ideal solution for making secure connections in tight spaces. Its small size, robust construction, and reliable contact make it a popular choice for data and signal transmission applications.
