The Piezoelectric Actuators developed by CEDRAT TECHNOLOGIES have the following outstanding characteristics: high force and large displacement in compact sizes, high resolution within the nanometre range, very short response time below 1 ms, life time greater than 10^10 cycles, low voltage supply below 150V DC, no backlash and no play, low power consumption when static, severe environment compatibility (vacuum, cryogenic, high temp,...).

In order to meet varying customer actuation specifications, CEDRAT TECHNOLOGIES has developped 3 different families of standard piezoelectric actuators with their corresponding drivers and controllers:

• Parallel Pre-stressed Actuators (PPA)
• Amplified Piezoelectric Actuators (APA®)
• Piezo Actuators' Mechanisms
• Drivers & Controllers
