TE Connectivity 770854-1 AMPSEAL 1.3mm Female Socket Terminal

The Component: Genuine TE Connectivity high-performance automotive crimp receptacle socket contact. AMPSEAL Sealed Series taxonomy / Female cylindrical receptacle contact component / Standard Plating Profile (High-Reliability Brass Base Alloy / Premium Tin Plated Surface Finish / 1.3mm Mating Pin Diameter Acceptance / Open-Barrel Wire Crimp and Insulation Support Wings / Heavy-Duty Powertrain, Industrial Engine ECM, Chassis Matrix, and Sealed Firewall Pass-Through Interconnect Contact / Component Part Number: 770854-1 / TE Internal Order Reference: 770854-1 / Global Logistics GTIN: 00505574347714).

Applications & Fitment: Engineered as a premium original equipment (OE) specification open-barrel female socket contact designed explicitly for harsh under-hood electronic control units (ECUs), extreme-vibration commercial vehicle powertrains, and environment-exposed chassis infrastructure. This AMPSEAL series female receptacle terminal is an absolute bench crimping, field harness building, and heavy-duty diagnostic loom repair staple across global agricultural, marine, industrial, and motorsport electronics fields. It is standardly deployed across high-integrity data and actuator streams, serving as the core internal contact seated securely within AMPSEAL multi-position sealed plug housings (including industry-standard 14-way, 23-way, and 35-way controller header interfaces). It features a high-retention 1.3mm (.051 inch) inner socket sleeve configuration that establishes a gas-tight, multi-point interface over its service life, preventing intermittent signal drops caused by severe thermal shock or mechanical vibration. Engineered to interface perfectly with the AMPSEAL housing's collective rear rubber "family seal" mat, its smooth outer stamping profile glides through the seal membrane without tearing the protective silicone entry paths. Its open-barrel rear architecture features precision conductor wings alongside structural insulation barrel arms, ensuring exceptional strain relief and high pull-out force resistance on standard automotive thin-wall low-voltage wiring cores. An essential component for industrial machinery technicians, engine management specialists, and custom commercial vehicle harness builders.
