Abstract: DRR-129
Text: Application Note AN111A Reed Switch Extended Shock Capabilities The maximum shock specifications in the Hamlin catalog are very conservative for most switches smaller than the DRx-xxx type. The 11 ms duration shock limit in particular is based upon early U.S. military specifications that predated the use of pneumatic shock tables. Since all reed switch
