The Component: Genuine Sumitomo 6185-0865 (Alternative manufacturer reference: PB295-02010). 2-Way female sealed connector plug housing (Black).

Series Taxonomy: Sumitomo RS Series (Standard Type 1). This system relies on strict physical color-keying to prevent costly errors on multi-plug engine branches.

Terminal Interface: 2-pin single-row inline matrix built for 2.3mm (.090) female socket terminals (such as the Sumitomo 8240-0264 crimp pins) tracking on a 5.6mm centerline pitch grid.

Locking & Sealing Security: Features a high-compression internal silicone face gasket and individual rear wire-entry single-wire seals (SWS). Terminal retention is secured by a front-loading 6918-1774 Terminal Position Assurance (TPA) loose lock plate.

Mating Complement: Connects seamlessly with the matching black Sumitomo male tab connector housing under part number 6188-0552.

Common Applications: Extensively specified across Japanese vehicle wiring networks—particularly Nissan, Mazda, and Mitsubishi platforms. It is the primary factory-specified repair plug for 2-wire water temperature sensors, radiator electric fan thermal switches, and camshaft/crankshaft position sensor pigtails.

Sumitomo 6185-0865 RS Series 2-Way Sealed Female Automotive Plug Housing

Restore absolute signaling accuracy, stable circuit tracking, and high-tier environmental armor to your vehicle's engine management networks with the genuine Sumitomo 6185-0865 2-way female sealed connector plug. Precision-molded to rigid Tier-1 original equipment automotive engineering parameters by Sumitomo Wiring Systems, this 2-pin inline socket block belongs to the globally trusted RS Series (Standard Type 1) interconnect family. Outfitted with an integrated high-compression silicone face seal and precise rear single-wire insulation paths, it establishes an unyielding, waterproof barrier that completely isolates low-voltage sensor lines from high-temperature engine oils, coolant splash, fuel vapors, and aggressive road grime.

The 6185-0865 carrier block is injection-molded from a premium, heat-stabilized Polybutylene Terephthalate (PBT) technopolymer substrate finished in an industrial black tone. This clean factory coloration acts as a critical visual index in dense wiring clusters, preventing accidental cross-mating with adjacent brown or gray connector feeds that run the same terminal layout. The internal 2-position cavity matrix is engineered specifically around a 2.3mm (.090) terminal footprint on a 5.6mm centerline pitch. Physical safety is anchored by a dual-action defensive system: an integrated top mechanical latching arm that clicks audibly onto its mating counterpart, paired with a front-inserting 6918-1774 secondary terminal position assurance (TPA) lock plate to arrest contact pins immovably against severe engine block vibration. Routinely deployed across Japanese automotive architectures as the primary replacement plug for coolant temperature senders, radiator fan switches, and camshaft sensors, this authentic component allows auto-electrical specialists to execute clean, zero-resistance factory pigtail restorations.
