D-sub connectors are the industrial standard for mass-terminal applications. The DBM9W4SA190 is a popular 9-pin, D-Sub, Male, straight, PCB connector. This connector is widely used in consumer electronics, industrial, and automotive applications.

The pre-wired DBM9W4SA190 connector includes 9 contacts. It is compatible with ribbon cable formats with a distance between contacts of 2.5+/-0.3 mm. The 9-pin connector has a maximum contact resistance of 2.48 mΩ. With a nominal insulation resistance of 1000 MΩ, it is capable of withstanding operating temperatures up to 125°C. The connector is also RoHS compliant for use in hazardous environments.

The main application areas for the DBM9W4SA190 are industrial control systems, telecom equipment, point-of-sale systems, and digital data recorders. It is also used in audio and video equipment, as well as automotive and medical applications. The connector is ideal for high-density applications, especially where a smaller size and tighter pitch are required.

The working principle of the DBM9W4SA190 connector is relatively straightforward. The connector consists of two components: an outer shell and a contact block. The contact block is composed of several contact sections, each with a row of contact pins. These pins are arranged in a line and are positioned at specific distances apart. The outer shell is designed to fit over the top of the contact block to keep the pins securely in place. When installed into a device, a wire or ribbon cable is connected to the contact block, and is then routed through the outer shell.

Once the connector is installed, it creates an electrical connection between the device it is connected to and the cable that is hooked up to it. The pins absorb any electrical signals that pass through them, and then transmit them to the destination. Due to the secure fit of the outer shell, electrical leakage is minimized, allowing for a more reliable signal transmission.

The DBM9W4SA190 connector is a dependable and robust solution for a variety of industrials and consumer applications. With its high contact resistance, reliable insulation, and compact size, this connector is sure to provide the right connection for your devices.
