The NMB-MAT 1608KL-05W-B39 belongs to the 1608KL series of compact axial cooling fans. Its 40 × 40 mm frame and 20 mm depth make it suitable for compatible industrial electronic assemblies where installation space is limited.
The fan uses a nominal 24 VDC brushless motor design. NMB documents an operating voltage range of 20-25.2 VDC for the corresponding -L00 and -L50 versions, making the series suitable for appropriately regulated industrial DC power systems.
Manufacturer specifications for the matching full-suffix variants list a fan speed of 6500 RPM and a maximum airflow of 7.4 CFM. These characteristics support forced-air ventilation of compatible electronic modules, heatsinks and equipment enclosures.
The series uses ball bearings designed for rotating equipment cooling applications. NMB specifies an L10 life expectancy of 60,000 hours at 25°C for documented -L00 and -L50 versions. Actual operating life depends on temperature, installation conditions and application demands.
The corresponding manufacturer-documented versions provide a maximum static pressure of 42.2 Pa, equivalent to 0.17 inches of water. This supports airflow through suitably designed ventilation openings and equipment cooling paths.
Full part-number suffixes distinguish monitoring functions. NMB documents locked-rotor output for 1608KL-05W-B39-L00 and tachometer output for 1608KL-05W-B39-L50. The actual connector, signal wiring and suffix must be confirmed before installation or replacement.

What is NMB-MAT 1608KL-05W-B39?
The NMB-MAT 1608KL-05W-B39 is a compact 24 VDC brushless axial cooling fan from the NMB Technologies 1608KL series. Its frame measures 40 × 40 × 20 mm, making it suitable for compatible industrial electronics cooling applications.
What is the operating voltage of 1608KL-05W-B39?
The nominal operating voltage is 24 VDC. NMB specifies a 20-25.2 VDC operating range for the fully identified 1608KL-05W-B39-L00 and 1608KL-05W-B39-L50 variants. The complete part number and product label should be checked before applying power.
What are the dimensions of 1608KL-05W-B39?
The fan has a 40 mm width, 40 mm height and 20 mm depth. It is commonly described as a 4020 cooling fan. Mechanical mounting dimensions and connector clearance should also be checked when replacing an existing unit.
What is the rated current of 1608KL-05W-B39?
NMB lists 0.06 A for the documented -L00 and -L50 variants. Some distributors list 0.08 A for fan assemblies using the shorter 1608KL-05W-B39 designation. Because the current specifications differ, verify the complete suffix and the electrical rating printed on the actual fan label.
What is the fan speed and airflow?
NMB documents 6500 RPM, maximum airflow of 7.4 CFM and maximum static pressure of 42.2 Pa for the corresponding full-suffix models. These are rated performance figures rather than guaranteed airflow after installation in an enclosure.
Does 1608KL-05W-B39 use ball bearings?
Yes. Manufacturer specifications for the -L00 and -L50 variants identify ball bearings and an L10 life expectancy of 60,000 hours at 25°C. Service life can vary with operating temperature, airflow restrictions and application conditions.
Does 1608KL-05W-B39 have three wires?
Common commercially listed assemblies have three wires, but the specific monitoring signal and termination depend on the complete part number. Before installation, confirm the supply polarity, third-wire function and connector pinout from the existing fan and manufacturer documentation.
What is the difference between 1608KL-05W-B39-L00 and 1608KL-05W-B39-L50?
Both manufacturer-documented versions share a nominal 24 VDC rating, 40 × 40 × 20 mm dimensions and comparable cooling specifications. The important difference is the monitoring signal: the -L00 version provides a locked-rotor output, while the -L50 version provides a tachometer output. They should not be treated as electrically interchangeable without checking the equipment's monitoring requirements.
Can 1608KL-05W-B39 replace FANUC A90L-0001-0510?
Some industrial spare-parts suppliers cross-reference 1608KL-05W-B39 with FANUC A90L-0001-0510. This association does not establish universal interchangeability. Verify the installed fan dimensions, operating voltage, rated current, connector type, wire arrangement and monitoring signal before selecting a replacement.
What is the noise level of the fan?
The manufacturer specifies 25.5 dB(A) for the documented -L00 and -L50 versions under their specified measurement conditions. Installed noise can differ due to enclosure resonance, airflow restrictions and surrounding equipment.
Is NMB-MAT 1608KL-05W-B39 discontinued?
NMB identifies the fully specified 1608KL-05W-B39-L00 and 1608KL-05W-B39-L50 models as end-of-life products. The manufacturer identifies 04020VA-24L-AL-00 as the replacement reference for -L00 and 04020VA-24L-AT-00 for -L50. The appropriate replacement depends on the required signal function and mechanical configuration.
What should be checked before ordering 1608KL-05W-B39?
Confirm the exact fan model 1608KL-05W-B39, any additional -L00 or -L50 suffix, 24 VDC nominal voltage, electrical current rating, 40 × 40 × 20 mm dimensions, airflow requirements, connector and wire configuration, locked-rotor or tachometer monitoring requirements, mounting arrangement and applicable equipment cross-reference. If the fan is installed in a FANUC control or servo system, check the full equipment and FANUC spare-part numbers before replacement.
