55137-1

TE Connectivity AMP Connectors's 55137-1 establishes new standards in Terminals - Specialized Connectors for renewable energy applications. Developed for photovoltaic string monitoring, it combines weatherproof integrity with precision current sensing capabilities.The Tube Cap design incorporates silver-plated copper alloy contacts that maintain <2m resistance after 25-year UV exposure. Its IP68-rated enclosure protects against dust ingress and high-pressure water jets.Featuring Crimp technology, the connection system resists galvanic corrosion in salt fog environments per IEC 61701. The tin-plated brass construction prevents fretting corrosion in vibrating installations.Optimized for 16-22 AWG solar cabling, the terminal's dual-spring contact design compensates for thermal expansion, maintaining constant pressure across -40 C to 120 C operating range.Black housings utilize sunlight-reflective pigments that reduce internal temperature by 15 C compared to standard materials. This color-coding system aligns with IEC 60445 international standards.
