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

Historical listing photographs: The gallery retains existing views from this listing's historical image set. They are not proof of current shipping stock. Complete original photographs and their source history remain in store records outside the current gallery.

Historical nameplate record: NMB 1604KL-01W-B50; separate T03; photographed 5 V DC, 0.21 A.

The retained complete rear has the historical label. The archived oblique side/rear shows only partial unreadable label detail, frame, leads and red plug. Historical identity does not verify supplied dimensions, bearing, full option or pinout.

Before ordering, confirm the full supplied model and option, electrical label, measured dimensions, condition, complete harness, connector and pinout. Historical images do not establish those offered-unit details.

Supplied unit verification required

The historical rear label reads NMB 1604KL-01W-B50, T03, 5V DC 0.21A; the archived historical oblique side/rear view shows partial, unreadable label detail together with the frame, lead segments and red plug. Earlier title/custom dimensions used 40 x 40 x 10 mm, while body/fan fields used 16 x 16 x 04 mm. Neither is a measurement of the actual supplied unit here. Confirm the full option, measured dimensions, bearing and actual harness before ordering; model digits and plug appearance are insufficient.

Historical images and annotations do not establish current shipping stock, condition, an unedited camera original, supplied electrical characteristics or equipment compatibility. Before ordering, confirm the full supplied label and option, measured dimensions, mounting, actual harness, connector keying and pinout. Send label and connector photographs for matching help.
