6. Core Material & Product Advantages

6.1 N21 Ceramic Material Features

• High electromechanical coupling coefficient for efficient energy conversion
• Large G-constant, making it ideal for sensing applications (superior to N6 material for detection/scanning scenarios)
• Stable performance within the rated temperature range (-20 °C to +60 °C)
• Sintered ceramic structure for high mechanical strength

6.2 Product Core Advantages

• Compact disc design (10mm×2mm) for space-constrained applications
• Bolt-On mounting style for easy, reliable installation and disassembly
• Single-layer structure for simple integration with electronic/mechanical systems
• Proprietary piezoelectric material for consistent performance
• 3D model available for pre-design and matching verification

7. Typical Applications

Optimized for sensing and low-to-medium power actuation scenarios due to N21 material’s large G-constant, typical applications include:
