Product details
3M's M4-38RK sets new standards in Terminals - Ring Connectors technology, optimized for high-density interconnection systems. This advanced terminal connector integrates innovative design features with precision manufacturing for superior electrical performance in automotive and industrial applications.The Circular architecture of this connector enables multi-axis connection capability. Unlike conventional designs, its geometry provides 360 contact coverage for maximum current transfer efficiency.Engineered for 3/8 Stud interfaces, this terminal features anti-rotation properties that prevent loosening under vibration. The precision-machined contact surface ensures <5m resistance.With a controlled 0.075" (1.91mm) specification, this component achieves optimal current density distribution. The material cross-section has been validated through finite element analysis for thermal management.The 0.680" (17.27mm) dimension incorporates chamfered edges for easier insertion. This ergonomic design reduces installation time while preventing insulation damage.The 1.340" (34.04mm) configuration provides sufficient leverage for torque application during installation. This design consideration prevents overtightening while ensuring proper compression.Designed with Free Hanging (In-Line) orientation, this terminal facilitates blind mating in complex assemblies. The self-aligning feature improves first-time insertion success rate to 99.8%.The Crimp method employed creates molecular-level bonding between conductors. This process achieves intermetallic fusion that withstands temperature cycling from -55 C to 125 C.Supporting 4 AWG range, this terminal accommodates both fine and coarse strand conductors. The dual-stage crimp profile ensures uniform compression without wire damage.Featuring Non-Insulated technology, this connector provides exceptional dielectric strength. The material formulation resists tracking and corona formation at voltages up to 600V.The Brazed Seam implementation delivers military-grade reliability in commercial applications. Specialized contact geometry reduces insertion force by 40% while maintaining high retention.
