The NMB-MAT 1606KL-05W-B59 belongs to the 1606KL series of compact axial cooling fans. Its 40 mm square frame and 15 mm thickness provide a space-efficient cooling configuration for compatible industrial controllers, electronic assemblies and equipment enclosures.
The manufacturer-documented 1606KL-05W-B59 variants operate at nominal 24 VDC, with a specified operating range of 22-25.2 VDC. The documented rated current is 0.062 A with approximately 1.5 W input power. Confirm the exact electrical rating when the complete model suffix is not supplied.
Manufacturer specifications identify 8000 RPM nominal speed, 8.1 CFM maximum airflow and 62.8 Pa maximum static pressure. These performance characteristics support forced-air heat removal in compatible compact electrical and electronic systems.
The 1606KL B59 fan series uses ball bearings in the manufacturer-documented variants. NMB lists an L10 life expectancy of 60,000 hours at 25°C, a statistical bearing-life measure that depends on actual temperature and operating conditions.
Different full-suffix versions provide different fan monitoring functions. NMB specifies locked-rotor detection for 1606KL-05W-B59-L00 and tachometer output for 1606KL-05W-B59-L50. The monitoring signal must be matched to the existing control equipment.
With its compact dimensions, 24 VDC design and published airflow characteristics, the fan can be evaluated for compatible industrial equipment maintenance. Replacement selection should account for mounting geometry, lead connections, airflow direction and any required fan failure or speed monitoring signal.

What is NMB-MAT 1606KL-05W-B59?
NMB-MAT 1606KL-05W-B59 is a 24 VDC brushless axial cooling fan from the NMB Technologies 1606KL series. Manufacturer-documented full-suffix versions provide a 40 × 40 × 15 mm frame, 8000 RPM nominal speed and 8.1 CFM maximum airflow.
What voltage does 1606KL-05W-B59 require?
The nominal rated voltage is 24 VDC. The manufacturer specifies an operating voltage range of 22-25.2 VDC for the documented -L00 and -L50 versions. Confirm the actual fan label and complete part number before applying power.
What are the dimensions of 1606KL-05W-B59?
The fan measures 40 mm wide, 40 mm high and 15 mm deep. This compact size is commonly described as a 4015 axial cooling fan. The installed fan's mounting holes, frame construction and wiring clearance should also be checked.
What is the rated current of 1606KL-05W-B59?
NMB lists 0.062 A for the manufacturer-documented B59 monitoring variants, corresponding to approximately 1.5 W of input power. Some supplier listings for the shortened model number specify 0.08 A. Because the supplied suffix is incomplete, verify the exact rated current from the complete fan label rather than assuming all listed assemblies are identical.
What are the fan speed and airflow specifications?
The manufacturer documents 8000 RPM nominal speed, 8.1 CFM maximum airflow, approximately 0.23 m³/min metric airflow and a maximum static pressure of 62.8 Pa. Actual installed airflow varies with ventilation resistance and operating conditions.
What bearing type does 1606KL-05W-B59 use?
The manufacturer-documented 1606KL-05W-B59 variants use ball bearings. Their L10 bearing-life rating is 60,000 hours at 25°C. This is a statistical design-life measure and should not be interpreted as a guaranteed operating duration.
Does 1606KL-05W-B59 have three wires?
Documented monitoring-signal versions such as 1606KL-05W-B59-B00 and 1606KL-05W-B59-B50 are supplied with three-wire leads. The additional conductor provides a monitoring function, but its behavior depends on the full catalog suffix. Confirm the installed cable and pinout before connecting the fan.
What is the difference between 1606KL-05W-B59-L00 and 1606KL-05W-B59-L50?
Both manufacturer-documented versions have nominal 24 VDC operation, 0.062 A rated current, 8000 RPM speed, 8.1 CFM maximum airflow and 40 × 40 × 15 mm dimensions. The important difference is the monitoring signal: -L00 provides a locked-rotor output, while -L50 provides a tachometer output.
What is the difference between a locked-rotor output and a tachometer output?
A locked-rotor output is used to indicate a fan rotation failure or locked condition according to the manufacturer's specified signal behavior. A tachometer output provides pulses related to fan rotation for compatible speed-monitoring circuits. These signals perform different functions and should not be interchanged without verifying the receiving equipment.
What is the noise level and operating temperature range?
The documented 1606KL B59 performance variants have a noise rating of 34 dB under specified measurement conditions. Series technical documentation lists an operating temperature range of -10°C to +70°C. Equipment enclosure temperature and installed airflow resistance may affect overall performance.
Is NMB-MAT 1606KL-05W-B59 discontinued?
NMB identifies the full-suffix 1606KL-05W-B59-L00 and 1606KL-05W-B59-L50 versions as end-of-life products. The manufacturer lists 04015SS-24N-AL-00 for the locked-rotor version and 04015SS-24N-AT-00 for the tachometer version. These replacement models have different performance and bearing specifications, so their suitability must be verified for the application.
What should be checked before ordering 1606KL-05W-B59?
Verify the exact model number 1606KL-05W-B59 and any additional -L00, -L50, -B00 or -B50 suffix, nominal 24 VDC supply, rated current on the fan label, 40 × 40 × 15 mm frame, mounting arrangement, 8000 RPM nominal speed, 8.1 CFM airflow, connector or lead configuration, wire polarity, locked-rotor or tachometer signal requirement and existing equipment compatibility. Where the complete suffix is missing, identify the installed fan before choosing a replacement.
