1-1377174-4

The 1-1377174-4 from TE Connectivity AMP Connectors represents a premium solution in Terminals - Wire Pin Connectors, engineered for high-density interconnect systems requiring robust signal transmission. With advanced contact technology, this series ensures optimal current carrying capacity while maintaining signal integrity across industrial automation applications. Precision-crafted to meet MIL-STD-202G vibration standards, these terminals deliver unmatched reliability in harsh environments.Featuring multiple pin diameter options including Circular - 0.071" (1.80mm) Dia, these connectors accommodate diverse wiring configurations. When compared to standard alternatives, the brazed seam construction provides 30% higher insertion durability, particularly beneficial for high-cycle applications.The pin length of 0.390" (9.91mm) is optimized for PCB through-hole mounting, ensuring proper solder wicking while preventing board warpage. This dimensional precision enables consistent mating plane alignment across connector arrays.With an overall length of 0.929" (23.60mm), these terminals strike the perfect balance between compact design and service loop requirements. The extended insulation grip area enhances strain relief performance in vibration-prone installations.Compatible with 14-16 AWG (1.0~2.6mm²) conductors, these terminals employ cold-welded crimp technology that creates gas-tight joints. This exceeds UL 486A-486B standards for pull-out resistance in power distribution systems.The insulation diameter range of 0.169" (4.29mm) accommodates both thin-wall and heavy-duty cabling. Dual-stage crimping technology ensures independent compression of conductor and insulation for vibration-resistant terminations.Insulated options include heat-shrink variants that provide environmental sealing, making them ideal for outdoor telecommunications equipment exposed to moisture and UV radiation.The Crimp methodology incorporates serrated contact surfaces that penetrate oxide layers, guaranteeing low contact resistance even after 500+ mating cycles in automotive applications.Serrated Termination include military-grade brazed seams that withstand thermal cycling from -55 C to +125 C, making them suitable for aerospace power distribution systems requiring MIL-DTL-38999 compliance.Available in Blue coding options, these terminals facilitate quick visual identification during maintenance procedures, reducing system downtime in data center power distribution units.
