The DE09-PL-23 is a 9-position D-subminiature plug connector featuring a 0.318" footprint designed for right-angle PCB mounting. It utilizes phosphor bronze contacts with gold over nickel plating and a steel shell with tin or zinc plating, housed in a PBT 30% glass-reinforced insulator rated UL94V-0. The connector is rated for 250V AC/DC maximum operating voltage with a 5 A current rating per contact, 20 mO maximum contact resistance, and 5000 MO minimum insulation resistance. It operates reliably across -55°C to +105°C with standard soldering process temperatures up to 235°C (or 260°C with optional Hi-Temp Nylon 6T insulator). This connector is commonly used in industrial control systems, data acquisition equipment, and general-purpose PCB interconnect applications requiring robust, compact D-sub connectivity.
