Independent reference images: verify the supplied version

This gallery shows model-reference photographs from the independent seller sources linked below, not brand-official photographs. The reference label identifies NMB 1604KL-04W-B49 M51 (DC12V 0.10A). They depict a different photographed unit, not current shipping-stock proof. Upstream image-processing history is unknown.

The source has NMB label styling and a pale three-cavity plug; the actual original has NMB-MAT styling and twisted red, black and white leads whose ends are outside its frame. These are separate units. The supplied termination, connector and pin assignment remain unverified.

The complete actual original listing photographs, including historical originals, are archived in the store records and omitted from this product gallery. Confirm the supplied complete model and option, electrical label, measured dimensions, condition, harness, connector keying and full pinout before ordering. No equipment compatibility, signal function or measured performance is inferred.

Existing title or metadata dimensions are historical listing information, not measurements verified by this reference. The different physical unit and harness presentation do not establish the actual supplied termination or pin assignment.

1604KL-04W-B49 M51 label and selection notes

The original listing photographs identify NMB-MAT 1604KL-04W-B49 M51. The M51 marking is printed separately in the label option box. Electrical values below are label transcriptions, not independently tested performance.

Label voltage 12V DC
Label current 0.10A
Pictured connection Twisted red, black and white leads; termination outside frame

Which identification should I match?

Compare 1604KL-04W-B49 M51 character by character, then check the mounting and actual connector. Similar base codes do not establish interchangeability.

Do the visible leads prove a signal function?

No. Lead count and plug appearance do not identify PWM, tachometer or alarm functions. Confirm the pinout before connection.

Exact-version dimensions and performance remain unconfirmed. Archived original listing photograph retained in store records.; photo support; quantity quote.
