This is a professional-grade DC compact fan with integrated tachometer function for external speed monitoring. The built-in sensor generates a speed-proportional square-wave signal, allowing real-time monitoring of fan performance. Electronic commutation is completely integrated, and the unit is protected against reverse polarity and motor lock.
Ideal for industrial automation, control cabinets, electronics cooling, power supplies, telecommunications equipment, and any application requiring fan speed feedback for monitoring or control purposes.
