2-1377174-3

The 2-1377174-3 by TE Connectivity AMP Connectors sets new benchmarks in Terminals - Wire Splice Connectors technology for railway signaling systems. This fail-safe connector maintains flawless operation despite constant vibration, temperature extremes, and electromagnetic interference in rolling stock applications.Implementing Butt Splice, Inline, Individual Openings technology, this connector achieves EN 50155 Category 1 vibration resistance. Testing at 5-200Hz frequency sweeps shows zero contact interruptions at 50m/s acceleration.With 2 protected channels, this terminal meets EN 45545-2 fire safety requirements. The ceramic-filled housing prevents toxic smoke generation during tunnel fires.The Crimp method creates gas-tight joints that withstand 1000 thermal shock cycles per EN 61373. The metallurgical bond prevents fretting corrosion from micro-vibrations.Accepting 10-12 AWG railway cables, this connector handles both 110V control circuits and 1500V traction power. The dual-material contacts prevent bimetal corrosion in DC systems.Fully Insulated materials maintain CTI 600 tracking resistance in polluted environments. Testing confirms >108 surface resistance after salt fog exposure per EN 60068-2-52.Incorporating Serrated Mating Area, this connector series achieves EN 50121-3-2 EMI standards. The triple-shielded design reduces RF emissions by 40dB at 1GHz compared to conventional railway connectors.The Yellow scheme complies with EN 50125-1 visibility requirements. Photochromic markings adapt to lighting conditions from bright sunlight to tunnel darkness.
