In an effort to optimize customer satisfaction and commercial off-the-shelf (COTS) availability of our products, General Micro Systems has defined five levels of ruggedization (R1-R5). These ruggedization levels are based on four characteristics: Shock rating, vibration rating, temperature range, and ingress protection (IP). These ruggedization levels are distinct from our packaging options. In other words, these R1-R5 levels can be used in conjunction with various levels of packaging that range from fully sealed for submersion to commercial interconnects for less expensive solutions.
Rugged Level I (R1) represents the commercial level of ruggedization. R1 systems are designed for applications that require a rugged computer, but cannot do with just any off-the-shelf ruggedized PC. This rugged level offers the lowest levels of shock, vibration, temperature, IP and cost.
Rugged Level II (R2) represents the next level up from the commercial level of ruggedization. R2 systems are designed for applications that require a little more shock, vibe, and IP, and also an extension of the low temperature specification. The deployment of these systems is often implemented such that they are located inside another more rugged enclosure.
Rugged Level III (R3) represents the “middle-of-the-road” option for ruggedness. R3 systems are designed for applications that require a rugged computer, but the full ruggedization is either unnecessary or cost prohibitive. R3 offers an optimized price-point for system ruggedization.
Rugged Level IV (R4) represents one level down from a fully ruggedized system. R4 systems are designed for applications that essentially need maximum ruggedization, but for which the cost of full ruggedization is prohibitive. The only differences between R4 and R5 are vibration and IP levels.
Rugged Level V (R5) represents the highest level of ruggedization that GMS has to offer. R5 provides the highest levels of shock, vibration, and temperature range, in a fully sealed submersible package.
* Vibration frequency for systems not including drives are tested between 5Hz – 2000Hz
