The 3036W4SAR99E20X is a D-SUB combination female connector designed for high-density signal transmission with 36 contacts and integrated threaded spacer clip. The connector features a steel metal shell with tin plating over nickel (minimum 315 µin tin over 40–80 µin nickel), PBT GF insulator material (UL 94 V-0, green), and gold-flash plated copper alloy signal contacts over nickel. Key dimensional specifications include a connector length of 67 mm (±0.31/-0.45 mm), width of 61.11 mm (±0.13/-0.12 mm), and height of 52.5 mm (±0.05/-0.2 mm), with a 10° mounting angle and PCB hole diameter of 3.1 mm (±0.1 mm) for 1.6 mm thick PCBs. The threaded spacer clips are copper alloy with minimum 200 µin tin over 80 µin nickel plating, and the maximum torque value for the thread is 6 in.lb. This connector is RoHS compliant (Directive 2002/95/EC) and is commonly used in industrial instrumentation, data acquisition systems, and equipment requiring robust, high-contact-count interconnections with secure mechanical fastening.
