7289-7782-40 - 2-Pin 250 Series Automotive Connector | Yazaki
The Yazaki 7289-7782-40 is a 2-position (2P) 250 Series sealed automotive connector housing, configured as a CONN 2P 250 LT GRY (light grey) receptacle. This is part of Yazaki's widely deployed 250 Series sealed connector family used in automotive wire-to-wire and wire-to-board harnesses for body electronics, lighting, and sensor circuits. 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.

CJ2602-000 - Circular MIL Backshell Heat-Shrink Adapter | TE Connectivity
The TE Connectivity CJ2602-000 is a circular military-specification heat-shrink backshell adapter designed to provide environmental sealing and strain relief on size-9A MIL-DTL-38999 Series III/IV connectors. It belongs to the Raychem TXR series of heat-shrinkable boot adapters, threaded onto the rear of the connector and terminated with a polyolefin shrink boot that seals the cable jacket. The part ships unassembled and is field-installed with a standard heat-gun ramp. A connector backshell is a mechanical accessory that mounts behind a circular or rectangular connector body to provide cable support, environmental sealing, EMI shielding, or strain relief. Backshells sit in the interconnect accessory hierarchy above cable clamps and below connector housings; this type is a heat-shrink adapter, meaning the boot is molded onto the cable jacket thermally rather than crimped or potted. The CJ2602-000 combines a machined aluminum adapter body (olive-drab cadmium over electroless nickel is the standard Raychem finish) with a Raychem ATUM or similar polyolefin shrink sleeve. Key features include an M12x1 thread for engagement to size-9A shell, anti-decoupling mechanism (self-locking per the TXR40SJ00-0806BI specification), compatibility with -55C to +200C operating temperature, and 360-degree shield termination via the boot. The strain-relief geometry reduces cable-axial load on the solder or crimp contacts inside the connector by an order of magnitude when properly heat-shrunk. The technical architecture relies on TE Connectivity's qualified Raychem molding compound formulation, qualified to the relevant sections of MIL-PRF-85049 and AS85049 for environmental backshells. The component carries TE's TXR40SJ00-0806BI internal specification and ships with full traceability paperwork. The thread coupling torque is typically 8-12 N·m depending on shell size and material. Typical applications include military tactical radios, avionics LRUs (line-replaceable units), naval combat-system electronics, ground-vehicle vetronics, and industrial-grade sealed sensor harnesses where the cable must survive flexure, fluid immersion, or sand/dust ingress. CJ2602-000 is regularly specified on platforms such as the Raytheon AN/PRC-155 and other US/Joint-Service programs. When designing-in CJ2602-000, verify cable-jacket outer diameter matches the supplied shrink-boot range; also confirm the connector shell is size 9A per MIL-DTL-38999 before installation. Failure to respect the heat-gun shrink temperature (typically 110C minimum recovery) will produce a defective seal.
DS562 4-Pin Connector, Female/Male Blade Terminals
The DS562 is a connector listed by Standard Motor Products with a female connector body, male and female terminal genders, four blade terminals in the connector configuration, and one blade terminal identified separately in the distributor specification. The available record does not establish the manufacturer’s complete electrical ratings, dimensions, or package drawing, so those values remain unverified. The part is associated with distributor and aftermarket listings rather than a clearly identified manufacturer datasheet. A connector is an electromechanical interface component that joins a wiring harness, printed circuit board, vehicle circuit, or other cable assembly to another electrical system. Connector terminology can include housing gender, terminal gender, terminal quantity, contact type, pin pitch, wire gauge, and mating orientation. DS562 appears in search results under multiple unrelated identities, so the identifier must be matched to the exact Standard Motor Products listing before ordering or design use. The verified distributor result identifies the connector gender as female, the terminal gender as male and female, terminal quantity as four and one, and terminal type as blade terminals. These are the principal searchable characteristics for this record. No verified voltage rating, current rating, insulation rating, operating temperature, enclosure rating, or dimensional drawing was supplied, so those specifications should not be inferred from the connector category. The part may be used in legacy wiring systems, repair assemblies, or equipment where the original harness uses the same connector geometry. Compatibility depends on housing dimensions, blade width and thickness, terminal spacing, locking mechanism, wire gauge, conductor size, and environmental sealing. The manufacturer, connector series, and mating half should be confirmed from the original equipment documentation or the relevant distributor technical drawing. Before procurement, compare the DS562 against the exact connector drawing and mating part, not only the MPN text. The verified pricing shown by RockAuto is $153.79 for the listed Standard Motor Products DS562 record, while the remaining commercial terms and stock conditions are not available in the supplied data. Pricing and availability should therefore be confirmed as of the current date. This page consolidates the verified distributor identity, connector attributes, sourcing links, and unresolved engineering-data warnings. It does not claim that similarly named products, including aerospace or Xilinx records, are interchangeable with this connector.
