The NMB-MAT 1608KL-05W-B69 is a compact 40x40x20mm (4020) DC cooling fan designed for industrial electronics where reliable airflow is critical—commonly used in Fanuc CNC systems, robotics controllers, servo drives, power supplies, control cabinets, PLC enclosures, industrial automation equipment, and embedded cooling channels.
This model is rated 24V DC, 0.13A, and uses a 3-wire / 3-pin lead configuration (tach/sense lead included, depending on controller design).
Notes: This B69 model (0.13A) can replace 1608KL-05W-B59 (0.11A) and 1608KL-05W-B39 (0.07A / 0.08A).
VERY IMPORTANT: 1608KL-05W-B69 comes in different connector variations. Please match your connector style to the photos. If you need the 3-pin male connector version, check here.
1608KL-05W-B69, 1608KL05WB69
(Also commonly substituted in-field for lower-draw variants when connector and fit match: 1608KL-05W-B59, 1608KL-05W-B39)
Please note that the following list is not exhaustive. Compatibility depends on the device's design and cooling requirements. It's essential to verify compatibility with the device manufacturer.
✔ Industrial Automation / Robotics: Fanuc robotics controllers, teach pendants (fan-cooled bays), servo drive enclosures, robot cell control cabinets, motion control racks
✔ CNC / Machining: Fanuc CNC control cabinets, spindle/axis drive bays, power supply cooling zones, I/O expansion enclosures
✔ Controls & Electronics: PLC panels, HMI enclosures, industrial PCs, embedded control boxes, automation power distribution cabinets
✔ General Industrial Cooling Uses: 24V DC cooling channels for tight spaces requiring 4020 fans (40x40x20mm)
☑️ Compact 4020 footprint for tight industrial control spaces
☑️ 24V DC fan commonly used in CNC/robotics control cabinets
☑️ 3-wire design commonly supporting tach/sense monitoring (controller dependent)
☑️ Higher current B69 variant can replace many lower-draw variants when fit and connector match
☑️ Ideal for restoring airflow and reducing overheating faults in automation equipment
