Pre-stressed piezoelectric actuator CEDRAT TECHNOLOGIES
PPA L Series

Parallel Pre-Stressed Actuators PPA L Series:
Designed by CEDRAT TECHNOLOGIES, these new models of Direct Piezo Actuators result from developments carried out under a CNES contract, the French Space Agency. PPA models are twice lighter than DPAs, with the same electromechanical properties. They are suited to dynamic applications and their compact size also makes their integration easier in mechanical assembly.
The L Series produce displacements up to 80 µm and can generate a pushing blocked force of 3500 N.

- The PPA40L
is the smallest size version of the Parallel Pre-stressed Actuator L series.
Stroke(µm): 40; Blocked force(N): 3500; Resonance frequency(Hz): 7750; Dimensions(mm): 57*23,5*18

- The PPA60L
is the middle size version of the Parallel Pre-stressed Actuator L series.
Stroke(µm): 60; Blocked force(N): 3500 Resonance frequency(Hz): 4750; Dimensions(mm): 77*23,5*18

- The PPA80L
is the biggest size version of the Parallel Pre-stressed Actuator L series.
Stroke(µm): 80; Blocked force(N): 3500; Resonance frequency(Hz): 4250; Dimensions(mm): 97*23,5*18
