Description

Series P and Series PHL piezo actuators are stack type actuators built in a multi-layer technique. PHL actuators are High-Load. These P and PHL actuators both come without a pre-load, but they can still withstand a medium pressure force. PHL actuators are designed for high-load applications.

These piezo actuators are encased in a stainless steel housing.

P and PHL series actuators should be fastened with screws or clamps on the actuator’s bottom plate. These actuators are not designed for dynamic applications.
