Description
The Delta AFB0612SH-ABF00 (also known as AFB0612SHABF00) is a compact, high-velocity DC brushless tubeaxial cooling fan measuring 60 × 60 × 25.4 mm (2.36 × 2.36 × 1.00 in). Powered by an efficient two-phase, four-pole motor architecture operating at 12 VDC, it delivers up to 34.15 CFM (58.0 m³/h) of airflow and 0.422 in H₂O (105.2 Pa) of maximum static pressure at 6000 RPM. Constructed with flame-retardant UL 94V-0 reinforced plastic for both frame and impeller, the assembly integrates a precision dual ball bearing system yielding an L10 service life of 70,000 hours at 40 °C. The unit includes triple UL 1007 AWG #24 wire leads supplying continuous power along with an open-collector frequency generator (tachometer) output for real-time speed monitoring and system-level thermal feedback.
Key Features
- High-Pressure Airflow: Delivers 34.15 CFM (58.0 m³/h) and 0.422 in H₂O pressure across tightly packed electronic modules.
- Precision Ball Bearings: Dual ball bearing architecture ensures continuous duty rated up to 70,000 hours at 40 °C.
- Tachometer Signal Output: Integrated third-wire open-collector frequency generator allows real-time rotational speed tracking by host controllers.
- Flame-Retardant Construction: Molded with high-strength UL 94V-0 PBT plastic frame and impeller for enhanced operational fire safety.
- Comprehensive Circuit Protection: Features impedance-protected locked rotor recovery and reverse polarity tolerance to prevent motor winding damage.
