STANDARDIZED SOLUTIONS FOR LIGHTWEIGHT ELECTRONIC EQUIPMENTThe Miniature Mount Series offer standardized solutions drawn from broad experience in the design of space conserving isolators for a variety of lightweight applications. They are suitable for use with circuit boards, sensors, displays, instruments, control and other electronic modules. Their compactness permits designs utilizing internal suspension arrangements, eliminating the need for sway space outside the case and providing an overall savings in weight.

A variety of configurations is offered so that the designer can select the geometry most appropriate to the applications. Miniature Mounts use specially compounded elastomers to assure control during resonant response.

All configurations are available with BTR® (Broad Temperature Range) elastomer, which provides excellent resonant control and is suitable for use over the temperature range of -65°F to +300°F (-54°C to +149°C). For applications where vibration isolation and returnability are paramount, selected styles are available using BTR® II elastomer which is suitable for use over the temperature range of -40°F to +300°F (-40°C to +149°C). For less demanding temperature requirements, the MGN Series uses natural rubber which is useful from -40°F to +180°F (-40°C to +82°C).
