The 51982-1 is a sealed terminal and splice connector manufactured from aluminum, designed for lightweight terminations in aerospace and defense applications. It features TE Connectivity's proven dry crimp technology with a perforated insert that penetrates aluminum oxides to form oxide-free, long-lasting terminations, achieving up to 60% weight reduction compared to copper terminals and 53% compared to drop-forged aluminum alternatives. The single-step crimp process simultaneously terminates the conductor and seals the connection against moisture ingress, eliminating the need for secondary sealing operations. Available in single-hole lug, dual-hole lug, and butt splice configurations, the terminal is constructed from aluminum with tin-over-nickel plating and is qualified for commercial aircraft use. Its grease-free design and compatibility with existing crimp tooling make it ideal for primary power feeders, grounding systems, and unmanned aerial vehicle applications where weight savings and reliability are critical.
