Magnetic Mounting for Sensor - Ø25mm Neodymium, 1/4-28 UNF Thread (25kg Pull Force)

BCNT Ø25mm Rare-Earth Neodymium Accelerometer Magnetic Mount – 1/4-28 UNF (25 kg Pull Force | Global Standard Vibration Stud Magnet) (BCNT-MAG-25-1/4-28)

The BCNT-MAG-25-1/4-28 is a high-precision Ø25 mm × 8 mm Rare-Earth Neodymium Accelerometer Magnetic Mount engineered by BCNT Technologies, India's leading vibration sensor hardware manufacturer. Designed in strict compliance with ISO 5348:2021 (Mechanical Mounting of Accelerometers), this mounting magnet delivers an exceptional 25 kg (55 lbs) magnetic pull clamping force to ensure maximum contact stiffness and uncompromised high-frequency vibration signal transmission up to 7.5 kHz.

Engineering Highlights & Physics Principles

• Sintered Neodymium-Iron-Boron (NdFeB Grade N45/N52) Core: Delivers intense magnetic flux density (Br > 1.32 Tesla) providing 25 kg vertical holding force, preventing sensor rocking and micro-chatter under severe machine acceleration.
• Precision CNC Turned 303/304 Stainless Steel Shielding Casing: Directs and concentrates magnetic flux lines into the ferromagnetic machine body while acting as an effective magnetic shield to protect internal piezoelectric shear crystals from EMI noise.
• Optical-Grade Face Flatness (<0.005 mm): Concentric fine lathe finish eliminates air gaps and maximizes acoustic transmissibility across bearing fault frequencies.
• Standardized 1/4-28 Female Thread (Imperial (UNF)): Precision CNC internal tapped thread with 100% thread gauge verification for zero-backlash stud engagement.
• High Mounted System Resonance (> 12.0 kHz): Optimizes mechanical interface stiffness to extend the linear flat measurement bandwidth for high-speed gearbox harmonics and bearing demodulation.

Recommended Predictive Maintenance Applications

• Route-based walkaround vibration surveys on centrifugal pumps, AC induction motors, fans, and cooling towers.
• High-frequency bearing defect analysis (PeakVue, Shock Pulse, Enveloping, Demodulation).
• Turbine, reciprocating compressor, and gearbox diagnostic health monitoring without permanent machine drilling.
• Compatible with leading accelerometer brands (PCB Piezotronics, Wilcoxon, CTC, Hansford Sensors, SKF, Meggitt, IMI).
