Technical Specifications

Brand NMB

Frame Size Verification required for the supplied unit
Rated Voltage 12V DC
Rated Current 0.46A
Product Category Industrial Cooling Fan

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: Image 3 is an unmodified original upper label detail showing NMB-MAT 1511FB-04W-B56, 12V DC, 0.46A. Image 4 is a separate original option-mark detail showing BB1. Both are separate partial pixel crops of original listing image 1; they are not a complete nameplate or a reconstructed continuous label. Original image 2 retains the complete actual angled rear view and black sleeved cable. These photographs do not confirm current shipping stock; verify the actual supplied label, dimensions, connector and pinout before ordering.

External reference photo - verification required: Image 1 is an external supplier photograph from ElecSpares, showing NMB 1511FB-04W-B56, 12V DC, 0.46A, with the BB1 marking. This is a different photographed unit with the 7151591 auxiliary number, different Minebea label wording and loose leads instead of the original listing black sleeved cable. Source image processing history is unknown, including the mountain background; this is not recovery of an unedited original or proof of current shipping stock. Original image 2 retains the complete actual angled rear view and black sleeved cable. Images 3 and 4 preserve separate partial upper-label and original BB1 option-mark details from the former original image 1; 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.
