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.
