The PMD1204PQBX-A is a compact, high-speed 4028 brushless DC cooling fan designed for applications requiring strong airflow and high static pressure in a limited space. Its 3-wire connection provides power, ground, and fan-speed feedback for compatible robotics, CNC, automation, industrial-control, and electronic equipment.
PMD1204PQBX-A, PMD1204PQBX-A(2), PMD1204PQBX-A(2)F, PMD1204PQBX-A.(2).F.GN, PMD1204PQBX-A.(2).GN
Suffixes may identify differences in the speed-sensor circuit, wire termination, connector, or production revision. Confirm the complete part number, voltage, current, connector shape, pin order, mounting pattern, and airflow requirements before treating suffix variants as interchangeable.
Compatibility is determined by the original fan specifications—not the equipment category alone. The installation must support a 40mm x 40mm x 28mm fan, 12V DC input, 0.57A operating current, 3-pin connection, and matching pinout.

✓ Confirm that the original fan is 40mm x 40mm x 28mm. A 40mm fan with a different thickness may not fit or provide equivalent cooling.
✓ Confirm a regulated 12V DC power source capable of supplying at least 0.57A continuously, with sufficient capacity for fan startup.
✓ This is a 3-wire tachometer fan, not a 4-wire PWM fan. It does not use a separate dedicated PWM-control wire.
✓ The typical wire functions are red for positive voltage, black for ground, and yellow for tachometer feedback. Always verify the actual connector pin order before applying power.
✓ A matching 3-pin housing does not guarantee a matching pinout. Industrial equipment manufacturers may use different wiring arrangements.
✓ This is a high-speed performance fan with an approximately 51.5 dBA noise rating. It is intended for strong cooling rather than quiet operation.
