The DBM-9W4S-A197 is a Combo D-series D-Subminiature socket connector designed for applications requiring mixed signal and power layouts. It features a 9W4 contact arrangement, which includes five size 20 signal contacts and four empty size 8 cavities, allowing for customization with separately ordered power contacts. The connector is rated for a maximum of 7.5A on its signal contacts and has a dielectric withstanding voltage of 500 VAC at sea level. Constructed with a durable steel shell with a pure tin over nickel finish and a black UL 94V-0 rated thermoplastic insulator, it operates reliably across a wide temperature range from -55°C to +125°C. Designed for .120'' (3.05mm) through-hole mounting, this connector is ideal for use in industrial and telecommunications equipment where a combination of signal and power lines is required in a single, space-saving interface.
