What materials are MC4 connectors typically made of?

MC4 connectors are typically made from high-quality, durable materials to withstand harsh environmental conditions. They are primarily constructed from UV-resistant plastic for the outer casing and copper or brass for the internal conductive components. The plastic ensures resistance to sunlight, moisture, and temperature fluctuations, while the copper or brass ensures efficient electrical conductivity. These materials combined provide reliable performance and longevity.
