Designed for unsealed automotive applications, it is validated to USCAR-2 specifications and meets stringent requirements from major automotive OEMs including PSA, Ford, Nissan, Toyota, and VW. The Pin-Alignment-Plate (PAP) construction supports high-temperature IR-reflow soldering up to 260\u00b0C and selective wave soldering. The stackable design allows single or ganged configurations, providing design flexibility without custom tooling. With 0.64mm signal pins rated at 6A and 500V, this connector is suitable for automotive comfort, infotainment, body electronics, and safety system applications.","working_principle":"The 34691-0080 operates as a wire-to-board interconnect:\n\n1. Contact System: The header features 0.64mm square pins that mate with corresponding female terminals in the receptacle housing, establishing electrical contact through spring-force engagement with tin-over-nickel plating.\n\n2. Polarization: The center key ensures correct mating orientation, preventing incorrect connections. USCAR-standard color coding provides visual verification.\n\n3. TPA (Terminal Position Assurance): The pre-assembled TPA device locks contacts into the housing, preventing back-out during vibration and thermal cycling.\n\n4. Stacking: The stackable header design enables ganged configurations (2, 3, or 4 bays) for multi-circuit applications within a common PCB footprint.","pin_description":"\n

      Note: Pin numbering follows USCAR standard. The 8-circuit header uses 0.64mm pins in a 2-row x 4-position arrangement on 2.54mm pitch. Optional 1.50mm and 2.80mm power blade positions are available in hybrid versions. Contact plating is tin over nickel on copper alloy.<\/p>","application_scenarios":"\n
