Subject: STANAG Interface for RMM
Does anyone have an experience on the in-service reliability of the STANAG 4575 interface for Removeable Memory Modules in terms of how often the RMM can be inserted/removed before replacement of the connector is necessary? We shall be using the MIL_DTL-24308E D-type connectors with our implementation. The standard requires a minimum durability of 500 make/break cycles for this connector. In the absence of supporting data this effectively lifes the interface at 500 times the average removal interval which is an unattractive proposition in terms of total ownership costs. Comparision wuith commercialy available non-STANAG interfaces for similar applications reveals claimed life-times of up to 25000 cycles. The truth probably lies somewhere in the middle - but where?
