Sumitomo 8100-3177 1.0mm (040) Male Terminal Pin - Sealed Series

The Component: Genuine Sumitomo Wiring Systems 1.0mm (040) male tab terminal pin. Features a high-conductivity copper alloy base metal construction with premium corrosion-resistant tin plating / Form-factored precisely for 1.0mm (040) micro connector interface systems / Multi-series terminal architecture fully compatible with HX Sealed, HV Sealed, and HVG Sealed series connector housings / Engineered for standard automotive AV, AVS, and AVSS wire types / Wire Insulation Wrap Design: Configured with dual rear crimping insulation wings to accept an individual single wire seal (SWS) / Component Part Number: 8100-3177 / Sumitomo Order Reference: 81003177.

Applications & Fitment: Engineered to provide highly reliable electrical contact and structural durability inside modern low-voltage, sealed automotive wiring harnesses. This authentic Sumitomo 1.0mm male terminal pin is a major original equipment manufacturer (OEM) factory standard heavily utilized across Japanese domestic market (JDM) automotive architectures, specifically found throughout modern Toyota, Honda, Nissan, and Subaru engine wiring configurations. It serves as the mating pin interface inside multi-position inline wire-to-wire connector plugs, commonly handling critical low-current signal pathways for engine control units (ECUs), oxygen sensors, throttle position links, and high-performance coil pack distribution looms. Stamped from highly resilient copper alloy and finished with a uniform tin-plated layer, the terminal resists copper oxidation and contact fretting under harsh engine bay conditions. The terminal architecture includes a specialized rear wrap design that captures the copper wire core in the forward crimp section while rigidly binding an automotive single wire rubber seal (SWS) in the rear secondary wing section, ensuring absolute moisture and dust isolation. Highly sought after by professional motorsport wiring specialists, diagnostic auto-electricians, and custom automotive wiring harness builders demanding factory-level connector restorations.
