TOKIN - Metal Sealed Multilayer Piezoelectric Actuators
ASB, ASL, and AHB Series
 |
|
The ASB/ASL and AHB series metal sealed actuators enhance the proven technology of the Tokin multilayer actuators by providing an airtight structure that protects the actuator from a variety of enviromental hazards. The actuators are much less influenced by ambient humidity because of insulation from the atmosphere.The metal case is Nitrogen filled and also provides a preload for the actuator. There are several mounting options available that afford flexibility of installation.
Features
The special features of Metal Sealed actuators:
- High reliability: Realization of MTTF = 36,000 hours (at 85C and 100 V).
- Airtight construction.
- Actuator assemblies are Nitrogen filled.
- Accurate positioning: Controllable in nm.
- Large generated force: 800 N
- High temperature case available (ASL series)
- High Displacement models available (AHB series)
- Available with various mounting options.
