Product Specifications

Review the technical data used for replacement matching, procurement comparison and engineering approval.

Photo source and supplied-unit verification: The gallery model-reference photograph is from independent seller ElecSpares, not brand-official photography. It shows a different photographed unit. Its prior processing history is unknown, and it is not proof of current shipping stock. Complete actual original listing photographs are archived in store records.

The reference shows NMB 1511FB-04W-B56, BB1, 12V DC and 0.46A. Its 7151591 auxiliary number, Minebea label wording, loose leads and mountain background differ from the original listing NMB-MAT unit with a black sleeved cable. Two separate original upper-label and BB1 option-mark crops remain available as partial identification evidence; they are not a complete or reconstructed nameplate.

Confirm the actual offered label, full ordering option, dimensions, condition, connector and pinout before ordering. Visible wire colors do not establish signal functions.

Confirm the supplied complete model and option, electrical label, measured dimensions, condition, harness, connector and pinout before ordering; the reference does not verify these supplied-unit details.

Notice: This is an industrial component. Please verify frame size, voltage, and connector type before replacement.

Original label - verify the supplied unit: The original listing photographs show NMB-MAT 1511FB-04W-B56, 12V DC, 0.46A, with the BB1 marking. The original listing has a black sleeved cable; its full connector and signal functions are not established by the photographs. These are observations of the original listing, not measurements or confirmation of current shipping stock. Dimensions, mounting, complete offered label, connector and pinout require verification before ordering.

Preserved original partial label details: The preserved upper-label crop is an unmodified original upper label detail showing NMB-MAT 1511FB-04W-B56, 12V DC, 0.46A. The preserved option-mark crop is a separate original option-mark detail showing BB1. Both are separate partial pixel crops of the historical original listing photograph; they are not a complete nameplate or a reconstructed continuous label. The complete actual angled rear view and black sleeved cable are retained in store records outside the current gallery. These photographs do not confirm current shipping stock; verify the actual supplied label, dimensions, connector and pinout before ordering.
