557-BULK

Designed for industrial automation systems, the 557-BULK by 3M sets new benchmarks in Terminals - Wire Splice Connectors reliability. This heavy-duty connector withstands continuous vibration and thermal cycling while maintaining flawless signal transmission in PLC and motor control applications.The Butt Splice, Closed End, Individual Openings design incorporates redundant contact points that ensure uninterrupted operation in critical processes. Manufacturing tests show 0% failure rates after 50,000 mating cycles.With 2 wire capacity, this terminal simplifies control cabinet wiring while meeting NEC wire fill requirements. Its modular architecture allows for field-expandable configurations.IDC technology provides maintenance-free connections that resist loosening under vibration. The self-locking mechanism exceeds UL 486A-B requirements for industrial equipment.Accepting 16-22 AWG conductors, the 590DC-CDG handles both signal-level and power circuits. The optimized contact geometry prevents fretting corrosion in high-current applications.The Fully Insulated material maintains dielectric strength above 1000VAC in oil-contaminated environments. This qualifies the connector for use in food processing and chemical plants.Incorporating Flame Retardant, Hinged Lid(s), this connector series achieves Category 5 shock resistance per IEC 60068-2-27. The military-grade construction withstands 100G mechanical shock pulses.Red coding follows ISO 3864 safety standards, enabling instant hazard recognition. The phosphorescent additives ensure visibility in low-light industrial settings.
