The 6070-2481 from Sumitomo Wiring Systems is a 250 Type ET automotive connector housing designed for 2-way inline wire-to-wire connections. Sumitomo identifies it as a 6.0mm (.250-type) connector for automotive wiring-harness applications.
The exact part is a female connector housing designed to accept female terminals. Its official mating housing is 6070-2471, a corresponding 2-way male 250 Type ET connector housing.
The 6070-2481 is an unsealed connector, meaning it does not incorporate a dedicated environmental sealing system. It is therefore primarily suited to protected vehicle or equipment locations rather than applications requiring direct water or dust sealing.
The housing is manufactured from PP polypropylene and has a natural color. Sumitomo identifies the retention design as a housing-lance type, in which the terminal is retained by a locking feature inside the connector housing.
Official compatible female terminals include 1500-0080, 1500-0081, and 1500-0082. These 6.0mm 250-type terminals cover different wire sizes: 0.3mm² for 1500-0082, 0.5–2.0mm² for 1500-0080, and 2.0–3.0mm² for 1500-0081. The appropriate terminal must therefore be selected according to the actual wire size.
The compatible terminals use brass construction with anti-corrosion surface treatment. For example, Sumitomo specifies a maximum initial contact resistance of 3mΩ for the 1500-0081 terminal and 6mΩ maximum after durability testing.
The official engineering drawing shows the 2-way ET female housing with an approximate 25mm depth, 10mm frontal width, and 21.8mm overall height. Final mechanical design should follow the dimensional tolerances shown in the current Sumitomo engineering drawing.
Sumitomo currently marks the 6070-2481 as “Old Series.” This makes it particularly relevant for maintenance, replacement, legacy wiring-harness production, and existing designs; new projects should confirm product availability and any recommended newer-series alternatives with Sumitomo.
