The WAGO 216-103 ferrule sleeve is a crucial component for creating robust and reliable electrical connections. Designed for wires with a cross-section of 1 mm² or AWG 18, this ferrule ensures a gas-tight and mechanically secure crimp, minimizing the risk of loose connections and signal degradation. The electro-tin plating provides excellent corrosion resistance, making it suitable for a wide range of industrial applications. It's an essential accessory for terminal blocks, contributing to the overall safety and performance of electrical systems.
