T3435502U is a circular DIN connector from Amphenol's signalmate® C091 (M16 Size) family of industrial connectors and cable assemblies. The connector is part of a modular series available in multiple configurations (M16 A, M16 B, M16 D, M16 D+, and M16 Q variants) with various coupling options including threaded, bayonet, and quicklock mechanisms. It operates over a temperature range of -40°C to +100°C and supports operating voltages up to 300V per IEC 60664-1 standard, with current ratings varying by position configuration (up to 10A for 2-4 positions, 7A for 5-8 positions, and 3A for 12-14 positions). The connector features excellent EMI shielding capability, thermoplastic dielectric material, and contact options including silver/gold plating with solder or crimp termination. These connectors are widely used in measuring instruments, equipment, and 4G/5G mobile radio networks where reliable power and signal connections with environmental protection are essential.
