Environmental

InMate products are tested in random vibration environments to best simulate the broad spectrum

Shock and vibration

of frequencies and amplitudes that may be encountered in typical applications. Actual system

resonant frequencies will depend on PCB construction and mounting details.

For critical, or unusual, shock and vibration environments, the performance of the system should

be independently verified.
