776228-4

The recommended installation screw size is a thread-forming (self-tapping) screw such as Delta PT, with a diameter of 2.50 - 3.00mm [0.099 - 0.118 inches] and a tightening torque of 0.6 - 0.8N·m. Customers should test screw sizes and types to verify their selection for the application. This position uses a 5-digit date code: the first 2 digits represent the year, the middle 2 digits represent the week number, and the last digit represents the day. Regarding materials, the receptacle housing is glass-filled PBT, the pins are tin-plated or gold-plated brass, and the gasket is silicone. Housing color serves as a mechanical keying feature — the receptacle can only mate with plug assemblies of the same color. The receptacle mates with plug assembly 770680 using reel-packaged terminals 770520 or loose terminals 770854. A recommended PCB layout is available for PCBs with a thickness of 1.57, and a recommended mounting hole layout is available for panels with a maximum thickness of 5.0. 776228-1 and 776228-5, as well as 776228-2 and 776228-4, feature a keyed design. Before tightening to the final torque, ensure the receptacle is flush with the panel surface on all sides. An alternative configuration is available if the panel thickness exceeds 2.0.
