Key Features

Compact 40 × 40 × 20 mm Cooling Fan

The NMB-MAT 1608KL-05W-B59 belongs to the 1608KL series of compact DC axial cooling fans. Its 40 mm square frame and 20 mm thickness provide a compact cooling configuration for compatible industrial controllers, electronic assemblies and machine equipment.

24VDC Brushless Motor

The manufacturer-documented -L00 and -L50 versions operate from a nominal 24 VDC supply, with a specified voltage range of 20-25.2 VDC, 0.08 A rated current and approximately 1.9 W input power. The electrical rating of the actual assembly should be confirmed from its complete part number.

8500RPM High-Speed Airflow

NMB specifies an 8500 RPM nominal fan speed, 9.5 CFM maximum airflow and 69.4 Pa maximum static pressure for the documented B59 variants. These characteristics support forced-air cooling of electronic components and equipment enclosures with appropriately designed airflow paths.

Ball Bearing Construction

The documented 1608KL B59 variants use ball bearings with a manufacturer-listed L10 life expectancy of 60,000 hours at 25°C. Actual operating life depends on thermal conditions, enclosure design and equipment usage.

Locked-Rotor and Tachometer Versions

Different complete model suffixes identify different monitoring functions. The 1608KL-05W-B59-L00 provides a locked-rotor output, while the 1608KL-05W-B59-L50 provides a tachometer output. The correct monitoring type must match the requirements of the connected equipment.

Industrial Equipment Replacement

The 40 × 40 × 20 mm configuration is suitable for evaluation as a replacement fan in compatible industrial electronic equipment. When servicing CNC controllers or servo drive systems, match the exact fan suffix, electrical connection, monitoring function and mounting dimensions before installation.

Applications

  • Compatible FANUC CNC controller and machine electronics cooling
  • Industrial servo drive and amplifier ventilation
  • Compact power electronics and heatsink cooling
  • Industrial PLC and automation controller enclosure ventilation
  • 24VDC electronic power supply cooling systems
  • Industrial communication and control board cooling
  • Machine control cabinet thermal management
  • Replacement of compatible 40 × 40 × 20 mm DC axial fans

Frequently Asked Questions

What is NMB-MAT 1608KL-05W-B59?
NMB-MAT 1608KL-05W-B59 is a 24 VDC brushless axial cooling fan from the NMB Technologies 1608KL series. Its manufacturer-documented -L00 and -L50 versions feature a 40 × 40 × 20 mm frame, 8500 RPM nominal speed and 9.5 CFM maximum airflow.

What is the rated voltage of 1608KL-05W-B59?
The nominal rated voltage is 24 VDC. NMB specifies an operating voltage range of 20-25.2 VDC for the documented 1608KL-05W-B59-L00 and 1608KL-05W-B59-L50 versions. Verify the actual fan label and supply requirements before installation.

What are the dimensions of 1608KL-05W-B59?
The fan measures 40 mm wide, 40 mm high and 20 mm deep. This size is commonly referred to as a 4020 axial cooling fan. The mounting arrangement, screw locations and available wiring clearance must also match the installed equipment.

What is the rated current of 1608KL-05W-B59?
NMB specifies 0.08 A for the manufacturer-documented -L00 and -L50 versions, with approximately 1.9 W input power. Some third-party listings for the abbreviated 1608KL-05W-B59 model specify 0.11 A. The complete model suffix and fan label should therefore be checked before assuming a specific current rating.

What are the airflow and fan speed specifications?
The manufacturer lists 8500 RPM nominal speed, 9.5 CFM maximum airflow, approximately 0.27 m³/min and 69.4 Pa maximum static pressure for the documented B59 versions. Installed airflow will vary with the resistance of the equipment's ventilation path.

What bearing type does 1608KL-05W-B59 use?
The documented -L00 and -L50 variants use ball bearings. NMB specifies an L10 expected life of 60,000 hours at 25°C. This is a statistical bearing-life figure rather than a guaranteed operating duration for every individual fan.

Does 1608KL-05W-B59 have three wires?
The documented monitoring-signal versions use three-wire leads. Two conductors provide DC power and the additional conductor supports a monitoring function. Wire colors, connector pin assignments and the output signal behavior must be verified against the full model suffix and equipment wiring diagram.

What is the difference between 1608KL-05W-B59-L00 and 1608KL-05W-B59-L50?
Both variants share the same documented 24 VDC rating, 0.08 A current, 8500 RPM speed, 9.5 CFM maximum airflow and 40 × 40 × 20 mm dimensions. The important difference is the monitoring function: the -L00 version provides locked-rotor detection, while the -L50 version provides a tachometer signal.

What is the difference between 1608KL-05W-B59 and 1608KL-05W-B39?
The manufacturer-documented B59 versions operate at 8500 RPM with 9.5 CFM maximum airflow and 69.4 Pa static pressure. The B39 versions operate at 6500 RPM with 7.4 CFM maximum airflow and 42.2 Pa static pressure. Both use a 40 × 40 × 20 mm frame, but their cooling performance differs.

Can 1608KL-05W-B59 be used in FANUC CNC equipment?
This model is sold for cooling applications in selected FANUC CNC control and drive systems. Compatibility must be confirmed using the existing fan label, equipment part number, 24 VDC power requirements, mounting dimensions, wiring connector and any fan monitoring signal.

Is NMB-MAT 1608KL-05W-B59 discontinued?
NMB identifies the fully specified 1608KL-05W-B59-L00 and 1608KL-05W-B59-L50 versions as end-of-life products. The manufacturer lists 04020VA-24N-AL-00 as the replacement reference for -L00 and 04020VA-24N-AT-00 for -L50. Replacement suitability must be confirmed against the electrical and mechanical requirements of the installed equipment.

What should be checked before ordering 1608KL-05W-B59?
Verify the exact model number 1608KL-05W-B59 and any additional -L00 or -L50 suffix, 24 VDC nominal voltage, rated current, 40 × 40 × 20 mm dimensions, 8500 RPM nominal speed, airflow requirements, ball bearing construction, mounting style, connector type, wire arrangement, locked-rotor or tachometer monitoring signal and compatibility with the existing equipment. When the full suffix is missing, inspect the installed fan label before selecting a replacement.
