The PPA-2014 is a double layer product recommended for all applications including energy harvesting, sensing applications, resonant actuation and force/deflection actuation. This product has a relatively high natural frequency compared to the other products which is beneficial for some applications. With two piezo layers it generally offers improved performance over the PPA-1014 but at a slightly higher cost. Due to its smaller size and good performance this is a popular product for many applications. This product has mounting and alignment holes along with Mide’s patented Piezo Protection Advantage.
