Hermetically Sealed Piezo-ceramic Actuators

Hermetically Sealed Piezo-ceramic Actuators

Hermetically Sealed Piezo-ceramic Actuators

Product catalog summary
Advantages at a Glance:
  • Extremely robust mechanical design suitable for high humidity and harsh environments.
  • Low leakage currents even after prolonged use, ensuring high long-term stability.
  • Adjustable stroke and fast response time of 0.1 ms.
  • High blocking forces up to 1-2 kN with low casing stiffness.
  • Pre-stressed with 30N for enhanced performance.
Ready for New Applications:

Piezo-ceramic multilayer actuators in stainless steel casings from CeramTec maintain leakage currents well under 100 nA after thousands of hours, making them ideal for humid environments. They require no special handling precautions, even in normal conditions.

High Blocking Forces:

CeramTec offers a power module for high blocking forces, integrating multiple actuators in a hermetically sealed casing for reliable continuous operation.

Lasting Function Even Under Water:

Conventional coatings offer limited moisture protection, leading to leakage currents over 1 mA within hours. CeramTec's hermetically sealed actuators with active moisture suppression provide a unique solution.

Actuators in Stainless Steel Casing:

The stainless steel casing acts as a 100% diffusion barrier, allowing operation even underwater. The bellows design reduces stiffness, enabling free expansion under voltage. A special process prevents moisture entrapment, ensuring a water-free environment.
