3212 J/2N ebm-papst: High-Reliability 92mm DC Fan
The 3212 J/2N is a premium compact axial fan from the ebm-papst 3200 J series. Measuring **92 mm x 92 mm x 38 mm**, this unit is a step up from standard consumer fans, featuring a fiberglass-reinforced PBT housing and impeller designed for industrial durability. Operating on **12 VDC**, it is widely used in medical devices, server power supplies, and industrial automation control panels. The specific designation **/2N** indicates two critical features: «N» for the standard speed/performance curve, and «/2» denoting a **Frequency Generator (Tachometer)** output signal, which allows the host system to monitor fan speed in real-time.
Detailed Technical Data
- Dimensions: 92 x 92 x 38 mm.
- Voltage: 12 VDC (Range 7 – 13.8 VDC).
- Airflow: Approx. 130 m³/h.
- Signal: 3-Wire (Red +, Blue -, White Tach).
- Noise: 51 dB(A).
- Bearing: Precision Ball Bearings.
Field Engineering & Diagnostics
Lifecycle State: Active. Diagnosis: The tachometer output is an open-collector signal. If the PLC reports a «Fan Fault,» check the pull-up resistor on the signal line. If the fan spins but sends no signal, the Hall effect sensor inside may be damaged. If it doesn’t spin, verify the 12V supply. Installation Advice: The 38mm thickness provides higher static pressure capabilities than thinner (25mm) fans, making it better for pushing air through dense heatsinks. Compatibility: Perfectly suited for Siemens S7-1200 high-speed counter inputs (HSC) to measure RPM. This allows for predictive maintenance; if RPM drops below a threshold while voltage remains constant, the system can flag a «Check Filter» or «Bearing Wear» alert before failure occurs.

Why the /2 Signal?
The tachometer signal is essential for mission-critical cooling. It provides positive feedback that the fan is actually rotating, not just that power is applied.
