Sumitomo 8240-0287 TS 025 Sealed Series Female Terminal Socket

The Component: Genuine Sumitomo 8240-0287 automotive sealed female socket crimp terminal contact. TS 025 Series / 0.64mm nominal tab sizing classification / Precision-formed heat-resistant copper alloy / High-durability Tin-plated finish / Loose piece strip tracking / Component Alias Code: 82400287 / Global Order Reference: 8240-0287.

Applications & Fitment: Designed as a high-density, factory original equipment (OE) micro-terminal link engineered to restore low-voltage sensor connections. This 025-size (0.64mm) female receptacle terminal is a standard wiring harness staple across major global Japanese passenger car architectures—including comprehensive deployment within Toyota, Lexus, Nissan, and Honda factory engine management systems. It serves as the definitive crimp socket replacement inside high-vibration engine sensors, electronic throttle control bodies (ETC), accelerator pedal position (APP) modules, camshaft/crankshaft position sensors, and compact electronic control unit (ECU) sub-harnesses. Sized precisely to handle micro-current logic signals safely without introducing localized voltage drops, it isolates fragile data paths from intermittent continuity drops. Highly vulnerable to internal leaf spring flattening, core wing split fractures, or locking tang distortion if field service technicians attempt terminal diagnostic tests by probing the front mating face with oversized multimeter needles, or if crimping is executed using generic, un-profiled non-automotive hand pliers.

Technical Attributes:

- Manufacturer Part Number: 8240-0287 / 82400287 (Brand: Sumitomo Wiring Systems / Genuine Factory Automotive Class)

- Product Series Taxonomy: TS 025 Sealed Series Interconnect System Family

- Component Typology: Female Receptacle Socket Crimp Terminal Contact

- Mating Terminal Sizing: 0.64mm (.025 inch) Nominal Blade Width Capacity

- Base Structural Compound: Premium high-conductivity, heat-resistant copper alloy substrate for superior spring-tension threshold memory

- Surface Treatment / Plating: Full-coverage Tin Plating (Sn) for advanced protection against oxidation and contact corrosion

- Environmental Application: Rated for Sealed waterproof housing tracks (Relies on independent wire cavity silicone seals to preserve complete isolation)

- Target Wire Section Profile: Optimized specifically for a 0.50mm² conductor cross-sectional area (Comfortably matches standard 20 AWG thin-wall automotive wire lines)

- Electrical Performance Threshold: Reference continuous current handling up to 7.0 Amps (Subject to local ambient thermal boundaries and core conductor material)

- Low-Voltage Circuit Resistance: High-conductivity path specification limited to an initial 8 milliohm Maximum resistance

- Post-Testing Retention Boundary: Capped at a maximum 16 milliohm path limit after extensive lifecycle, structural aging, and vibration durability tests

- Insulation Safety Threshold: Preserves a secure 100 Megohm Minimum isolation line at 500VDC to prevent cross-cavity logic tracking leakage

- Companion Mating Terminal: Links perfectly with the corresponding TS 025 series male tab pin contacts, such as the 8100-3617 or 8100-3455 series

- Compatible Housing Systems: Snaps cleanly into 0.64mm TS-series matching female connector blocks, including the 6189-1161, 6189-7020, 6189-7073, and 6189-7246 plug lines

- Associated Wire Sealing Grommets (Not Included): Accommodates individual silicone rubber 0.64mm single wire cavity seals, including Sumitomo part numbers 7165-1043, 7165-1312, 7165-0796, and 7165-0891 depending on conductor outer jacket outer diameters
