T3401002U is an M16 D circular DIN connector from Amphenol's signalmate® C091 family, designed for industrial applications requiring robust environmental protection and signal integrity. The connector features a metal screw coupling system with IP65/67/69K rating when mated, thermoplastic dielectric material, and silver/gold contact plating for reliable performance. It supports 2 through 8, 12, and 14 position configurations 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 with contact resistance less than 5mO, insulation resistance greater than 10¹²O, and operates over a temperature range of -40°C to +100°C. Contact termination options include solder and crimp, with AWG range from 18 to 28, and the connector achieves UL 94 V0 flammability rating with 720 hours salt spray corrosion resistance. These specifications make it ideal for measuring instruments, equipment, and 4G/5G mobile radio network applications where environmental sealing and signal integrity are critical.
