Frequently Asked Questions
What is NMB-MAT 2406KL-05W-B59?
NMB-MAT 2406KL-05W-B59 is a 24 VDC brushless axial cooling fan from the NMB Technologies 2406KL series. Manufacturer-documented full-suffix versions include 2406KL-05W-B59-L00 and 2406KL-05W-B59-L50, both featuring a 60 × 60 × 15 mm frame, 4600 RPM nominal speed and 18.3 CFM maximum airflow.
What is the rated voltage of 2406KL-05W-B59?
The nominal rated voltage is 24 VDC. NMB specifies an operating voltage range of 10-27.6 VDC for the documented -L00 and -L50 variants. Verify that the equipment power supply and wiring meet the applicable electrical requirements before installation.
What are the dimensions of 2406KL-05W-B59?
The fan measures 60 mm wide, 60 mm high and 15 mm deep. It belongs to the 6015 axial cooling fan size class. Mounting hole positions, frame construction and wire clearance should also be checked before selecting a replacement.
What is the rated current of 2406KL-05W-B59?
The manufacturer specifies a rated current of 0.10 A for the documented -L00 and -L50 versions. Both have a published rated input power of 2.4 W. Other special assemblies using the abbreviated model designation should be checked against their complete part number and fan label.
What are the fan speed and maximum airflow specifications?
NMB specifies 4600 RPM nominal speed and 18.3 CFM maximum airflow, equivalent to approximately 0.52 m³/min. Actual airflow after installation depends on equipment ventilation resistance and operating conditions.
What is the maximum static pressure of 2406KL-05W-B59?
The manufacturer specifies a maximum static pressure of 51.2 Pa, equivalent to approximately 0.20 inches of water. This is a fan performance limit and does not indicate the airflow available at every operating pressure.
What bearing type does 2406KL-05W-B59 use?
The manufacturer-documented B59 variants use ball bearings. NMB lists an L10 life expectancy of 70,000 hours at 25°C. This represents a statistical bearing-life rating and does not guarantee an individual fan will operate for that duration.
Does 2406KL-05W-B59 have three wires?
The documented -L00 and -L50 configurations have three-wire leads. Two wires provide DC power, while the additional wire supports the variant-specific monitoring output. Connector style, wire identification and signal behavior must be verified using the complete fan designation.
What is the difference between 2406KL-05W-B59-L00 and 2406KL-05W-B59-L50?
Both documented versions share nominal 24 VDC operation, 0.10 A current, 4600 RPM speed, 18.3 CFM airflow and 60 × 60 × 15 mm dimensions. The -L00 version provides a locked-rotor output, while the -L50 version provides a tachometer signal. They should not be treated as electrically interchangeable when fan monitoring is required.
What is the difference between 2406KL-05W-B59 and 2410ML-05W-B59?
The 2406KL series uses a 60 × 60 × 15 mm frame, while the 2410ML series uses a 60 × 60 × 25 mm frame. The two series have different mechanical thicknesses and model-specific cooling characteristics. A matching 24 VDC voltage does not establish interchangeability.
Is NMB-MAT 2406KL-05W-B59 discontinued?
NMB marks the documented 2406KL-05W-B59-L00 and -L50 versions as not recommended for new designs and identifies a part-number change. Distributors list the legacy versions as discontinued. NMB provides 06015KA-24N-AL-00 as the replacement for -L00 and 06015KA-24N-AT-00 for -L50. These references must be matched to the required monitoring function.
What should be checked before ordering 2406KL-05W-B59?
Verify the complete model number 2406KL-05W-B59 and any additional -L00 or -L50 suffix, nominal 24 VDC voltage, 0.10 A rated current, 2.4 W power rating, 60 × 60 × 15 mm dimensions, 4600 RPM speed, 18.3 CFM maximum airflow, 51.2 Pa maximum static pressure, ball bearing construction, rib-type mounting, three-wire connection, connector details and locked-rotor or tachometer monitoring requirements. For legacy equipment, compare the full specifications of any replacement rather than selecting a fan based on frame size alone.
