Manufactured with a tin-plated copper terminal and a blue nylon insulation sleeve, the 31903 provides excellent electrical conductivity, corrosion resistance, and mechanical strength. Its closed-barrel crimp design ensures a reliable connection when installed with the appropriate crimping tool, while the insulated support helps protect the wire from vibration and strain. The terminal is rated for 300 V operation and temperatures up to 105°C (221°F).
