1608KL-05W-B39 NMB Technologies Miniature 24V DC Axial Cooling Fan
The NMB Technologies 1608KL-05W-B39 (NMB-MAT series) is a premium, ultra-compact DC brushless axial cooling fan engineered for precise spot cooling and thermal management in space-restricted electronic frameworks. Featuring a rigid 40mm square frame footprint and a 20mm depth profile, this fan delivers concentrated, high-speed directional ventilation against system backpressure.
Operating on a standard 24V DC supply, this high-efficiency fan utilizes a precision dual ball bearing system capable of running at 6500 RPM while maintaining minimal power consumption (1.44 Watts). Built with an integrated 3-wire design that supports tachometer/speed sensor signal monitoring, it ensures real-time operational feedback for system safety. It stands as a vital and dependable replacement component for Fanuc CNC machine drives, automated servers, power supply housings, and miniature equipment instrumentation.
