EFB1324SHE-EP - 127x127x38mm 12738 DC24V 1.38A Axial 4-Wire Lead with PWM and Speed Signal Cooling Fan

The EFB1324SHE-EP is a high-performance 24V DC axial cooling fan in a 127mm x 38mm form factor. It uses a 4-wire lead (power, ground, speed signal, and PWM control) for applications that need strong airflow, high static pressure, and speed control—commonly found in automation cabinets, robotics systems, CNC electronics, industrial power supplies, and networking equipment.
