- These mounts excel in space-constrained applications requiring minimal vertical height
- The series offers center-bonded construction for consistent performance across temperature ranges
- Advanced silicone elastomers provide excellent damping and broad temperature capability
- Installation options include both mechanical stake and snap-in designs for varied mounting needs
In today's aerospace and defense applications, protecting sensitive electronic components from vibration and shock is critical for ensuring reliable performance and extended equipment life. The LORD MCB Series of miniature mounts offers a sophisticated solution for isolating lightweight electronic equipment while maintaining strict space and weight requirements.
Design Features and Construction
The LORD MCB Series represents a careful balance of engineering decisions aimed at maximizing isolation performance while minimizing size and weight.
The mounts utilize a center-bonded construction that sandwiches specially formulated silicone elastomer between precision-machined aluminum components. This design approach creates highly consistent performance characteristics across all axes of motion while maintaining excellent durability. The metal components are typically manufactured from high-grade aluminum alloys like 2024-T4 and 303 stainless steel, with surface treatments for environmental protection.
Performance Characteristics
The LORD MCB Series delivers reliable vibration isolation performance across a range of challenging conditions.
Natural frequencies for the series typically fall between 75-230 Hz depending on the specific model and loading conditions. This frequency range makes these mounts particularly effective at isolating higher frequency vibrations common in aerospace applications. The mounts maintain their performance characteristics across an impressive temperature range of -65°F to +300°F (-54°C to +149°C), making them suitable for both internal and external equipment mounting locations.
Key Applications
Understanding where the MCB Series excels helps engineers make informed mounting decisions for their specific needs.
Circuit Board Protection
The MCB Series particularly shines in protecting sensitive circuit boards from damaging vibration. Their compact form factor allows them to be integrated directly onto boards while maintaining clearance requirements. The controlled stiffness characteristics help prevent board flexing that could damage components or solder joints.
Instrument Panel Components
Modern aircraft instrument panels contain sophisticated electronic displays and control units that require careful vibration management.
The MCB Series provides:
- Reliable isolation performance
- Minimal vertical stack height
- Multiple mounting configurations
- Predictable long-term performance
- FAA compliance where required
Navigation System Components
The precision requirements of modern navigation systems demand exceptional vibration control. The MCB Series delivers the necessary isolation while maintaining tight positioning tolerances critical for navigation accuracy.
