7289-7782-40 概要
What is a sealed automotive connector? A sealed automotive connector is an environmentally protected electrical interconnect designed to withstand the harsh conditions found in road vehicles, including temperature extremes, vibration, moisture, dust, and chemical exposure. Sealed connectors use integrated grommets, terminal position assurance (TPA) locks, and wedgelocks to maintain IP67 or higher ingress protection ratings. The 250 Series sits within the broader automotive connector taxonomy (sealed connector -> wire-to-wire connector -> automotive interconnect -> electromechanical component), serving as a workhorse interface for low-to-mid current signal and power circuits up to roughly 20A depending on the terminal selected.
Key features of the 7289-7782-40 include the 250 Series form factor, a 2-position cavity arrangement, light grey color coding for circuit identification, integrated latch and TPA locking geometry, and compatibility with Yazaki 250 Series sealed terminals. The housing accepts standard 250 Series female terminals (typically tin or gold plated, crimp termination), and pairs with the corresponding 250 Series plug housing. The light grey keying prevents mis-mating with connectors of the same series but different keying colors used elsewhere in the harness.
Technical depth: the 250 Series connector system is engineered around a 9.5mm pitch cavity arrangement, with terminal cavities designed to accept Yazaki's 250 Series contacts that handle signal and low-current power up to the terminal's rated current. The connector housing is molded from high-temperature thermoplastics rated for under-hood and chassis environments, providing resistance to automotive fluids, ozone, and UV exposure. The mating interface includes a primary latch and secondary lock (TPA) for terminal retention under vibration.
Typical applications include automotive interior and exterior lighting circuits, body control modules, sensor interconnects (temperature, pressure, position), seat and mirror harnesses, and chassis wiring where sealed environmental protection is required. The 250 Series is also deployed in commercial vehicle and off-highway equipment applications where automotive-grade reliability is required.
When designing with this connector, verify terminal selection and wire gauge compatibility per the Yazaki 250 Series terminal specification. Ensure proper TPA engagement during assembly - incomplete TPA seating is a common cause of field failures. Confirm sealing plug usage in unused cavities for IP rating compliance.

主な用途
7289-7782-40 の用途: 6 件s: Automotive Exterior Lighting Harness, Body Control Module Sensor Interconnects, Automotive Door Harness and Mirror Connectivity, Chassis and Underbody Sensor Wiring, Commercial Vehicle and Off-Highway Equipment, Interior Lighting and Accent Harness.
Automotive Exterior Lighting Harness
The Yazaki 7289-7782-40 is widely deployed in automotive exterior lighting circuits including headlamps, tail lamps, turn signals, and side marker lights where sealed environmental protection is required. The 250 Series 2P configuration handles the typical two-wire interface for LED or incandescent lamp assemblies, with the sealed housing providing IP-rated protection against water ingress, road salt, and underbody contamination. Light grey keying (LT GRY) prevents mis-mating in harnesses using multiple 250 Series connectors. Rated current is determined by the 250 Series terminal selected - typically supporting the 2-5A range common in lighting loads.
おすすめ
Body Control Module Sensor Interconnects
The 7289-7782-40 provides the sealed interface for sensor interconnects routed to body control modules (BCMs), including temperature sensors, position sensors, and switch signals. The 2-position cavity arrangement handles signal-plus-ground or signal-plus-power pairs typical in automotive sensor harnesses. The integrated TPA (Terminal Position Assurance) and primary latch maintain terminal retention under vibration, a critical requirement for chassis-mounted sensors. The high-temperature thermoplastic housing tolerates under-hood thermal exposure, and the sealed design prevents moisture intrusion that could cause corrosion or signal drift.
おすすめ
Automotive Door Harness and Mirror Connectivity
Inside door panels and mirror assemblies, the 7289-7782-40 delivers compact sealed connectivity for power mirror adjustments, door lock actuators, and side mirror turn signals. The 250 Series 2P form factor fits within the constrained geometry of door harness routing channels while providing sealed protection against water ingress during door openings and weather exposure. Light grey keying aligns with the harness design conventions used by major OEMs for door-side 2P interfaces. The connector's vibration resistance is essential given the door's continuous motion throughout the vehicle's service life.
おすすめ
Chassis and Underbody Sensor Wiring
The 7289-7782-40 is suited to chassis-mounted sensors including wheel speed sensors, ride-height sensors, and underbody lighting harnesses where exposure to road splash, salt, and debris is constant. The sealed 250 Series construction provides IP-rated protection at the connector interface, while the high-temperature thermoplastic housing tolerates underbody thermal cycling from exhaust proximity and ambient extremes. The 2-position arrangement handles the typical signal/power pair used by chassis-mounted sensor interfaces. The integrated seal system and TPA lock maintain reliable contact under sustained vibration.
おすすめ
Commercial Vehicle and Off-Highway Equipment
Beyond passenger vehicles, the 7289-7782-40 250 Series connector is deployed in commercial trucks, agricultural equipment, and construction machinery where automotive-grade reliability is required but at higher vibration and contamination levels. The sealed housing, TPA locking, and high-temperature construction translate directly to the harsher service environment of off-highway applications. The 2P configuration handles accessory lighting, sensor interfaces, and auxiliary power circuits typical in commercial vehicle harnesses. Light grey keying supports OEM harness design conventions in this segment.
おすすめ
Interior Lighting and Accent Harness
Interior ambient lighting, footwell lamps, and decorative accent lighting circuits use the 7289-7782-40 for compact sealed connectivity in cabin environments. The 2P arrangement handles the LED power pair typical in modern interior lighting, and the light grey keying supports multi-zone interior harness designs. While interior environments are less harsh than exterior underbody locations, the sealed 250 Series construction still provides protection against beverage spills and cleaning chemical exposure common in cabin service.

設計ノート
Always verify TPA (Terminal Position Assurance) full engagement during harness assembly - incomplete TPA seating is the leading cause of field failures in 250 Series connectors. The TPA must audibly click into the locked position after terminal insertion. Use a gentle pull test (5-10 N) on each terminal after TPA engagement to confirm retention. Field failures from unseated TPAs manifest as intermittent connection, especially under vibration.
Plan harness routing to avoid tension on the 7289-7782-40 connector body - all strain should be absorbed by the wire bundle strain relief, not the connector housing. Maintain a minimum 50mm straight wire section behind the connector before any bend to prevent terminal back-out under vibration. In door harness applications, account for the door's full range of motion to avoid flex fatigue at the connector interface.
The 7289-7782-40's current rating is determined by the 250 Series terminal selected, not the housing itself. For typical 16-18 AWG terminals, derate to 80% of the terminal's nominal current rating in continuous-duty applications to keep the contact temperature within the housing material's rated limit. For lighting circuits with inrush currents (LED driver startup, incandescent cold filament), verify the terminal's inrush rating, not just the steady-state rating.
When using the 250 Series with a wire-to-board header arrangement, ensure the PCB header's mating face is properly aligned within +/-0.5mm of the harness-side connector's mating axis to prevent seal damage during engagement. Mount the PCB header with adequate mechanical support - the connector retention force should not be carried by the solder joints alone. Use threaded standoffs or boardlocks for high-vibration environments.
