L777TSEG09POL2RM8 is a D-Sub connector featuring stamped and formed contacts with straight PCB termination and one metal shell design, compliant with MIL C24308. The connector accommodates 9 contacts with a mating force of 3.05 kg (6.74 lb) maximum and unmating force of 0.36 kg (0.79 lb) minimum, and includes boardlock with front screwlock (RM8) mounting option with M3 or #4-40 threaded inserts. Electrical specifications include a 5A current rating, 600V AC/rms voltage rating at 50Hz, 1000V AC/rms withstanding voltage, 5000MO insulation resistance, and 10mO maximum contact resistance. The connector operates across a temperature range of -55°C to +125°C and features brass contacts with selective gold plating (0.4µm flash or 0.76µm standard), a steel shell with tin over nickel plating, and a glass-filled thermoplastic insulator (UL 94V-0). This design is ideal for industrial, telecom, and standard I/O applications requiring reliable, economical PCB-mounted connections.
