NAC5021-Hxx
Noliac Damage Tolerant Stack
NAC5021-Hxx is one of Noliac damage tolerant actuator stacks. It is a multilayer actuator that can be stacked to match your requirements. The fuse technology of the damage tolerant stack fuses out any damaged ceramic element and the remaining ceramic elements continue to operate. This makes the damage tolerant stack an effective way to ensure high reliability for critical applications. The damage tolerant stack provides a stroke up to 112.2 µm and blocking force up to 2060 N depending on the height of the stack.
