Description
The NMB 06025SS-24K-AL-D1 is a compact, energy-efficient 24 VDC brushless axial cooling fan designed for continuous thermal management in high-reliability industrial systems. Built in a standard 60 x 60 x 25 mm (2.36 x 2.36 x 0.98 inches) PBT plastic frame, this model incorporates high-precision dual ball bearings for enhanced thermal longevity. Operating on a 24 VDC supply with an ultra-low rated current draw of only 0.06 A (1.44 W power consumption), it features a 3-wire lead assembly (+Red, -Black, Yellow FG) terminated with a 3-pin connector for real-time tachometer speed telemetry and closed-loop hardware monitoring.
Key Features
- Industry-standard 60 x 60 x 25 mm (2.36 x 2.36 x 0.98 inches) footprint manufactured with UL 94V-0 rated PBT plastic housing.
- Ultra-low power operation drawing 24 VDC / 0.06 A (1.44 W) for reduced energy usage and minimized thermal dissipation.
- 3-Wire Lead Wire configuration (+Red, -Black, Yellow 3rd Wire) featuring FG (Frequency Generator) tachometer speed output.
- Pre-fitted 3-pin connector assembly for quick plug-and-play installation into system controller boards.
- High-precision dual ball bearing system guaranteeing an L10 life expectancy of 60,000 hours at 40°C ambient.
- Built-in electronic motor protection including Auto-Restart on locked rotor condition and Reverse Polarity Protection.
