C09131G0071002U is an M16 D circular DIN connector from Amphenol's signalmate® C091 family, designed for industrial applications requiring robust signal and power connections. The connector features a metal screw coupling system with IP65/67/69K environmental protection when mated, thermoplastic dielectric material, and silver/gold contact plating for reliable performance. It supports multiple pin configurations (2 through 8, 12, and 14 positions) with current ratings of 2-3 positions at 10A, 5-8 positions at 7A, and 12-14 positions at 3A at +40°C. The connector offers excellent EMI shielding capability, operates across a temperature range of -40°C to +100°C, and is rated for up to 500 mating cycles with silver plating or 1000 cycles with gold plating. Key electrical characteristics include insulation resistance greater than 10¹²O, contact resistance less than 5mO, and compliance with UL 94 V0 flammability standards. This connector is ideal for measuring instruments, 4G/5G mobile radio networks, and other applications demanding high-integrity connections with superior environmental protection.
