The Component: Genuine Sumitomo 8240-0452 / 8100-0452 female automotive sealed crimp terminal contact. TS Sealed 0.64mm (.025) Series tin-plated copper alloy female socket box terminal (Reel Form / Loose Piece Cross-Ref: 8240-0452-L / Master Reel Packaging Track: 8100-0452).

Applications & Fitment: Engineered as a high-reliability factory original equipment (OE) female socket interface for low-voltage, high-density sensor networks and critical signal communication arrays. Universally specified across global Japanese passenger car and commercial transport platforms (most notably throughout Toyota, Lexus, Honda, and Nissan factory wiring looms) to populate multi-position TS series waterproof receptacle connector plugs.

Highly vulnerable to internal contact spring tongue deflection or setting deformation if back-probed aggressively with non-standard multimeter workshop diagnostic pins, or barrel collar fracture if crimped using generic un-profiled hand tools during harness field repairs.
