Now, with such a large portfolio, how does one select the right series for the right application? Piezo actuators can operate with nanometer-order resolution in all series if the noise level of the drive signal is suppressed. Among them, the AE series and AER series have extremely high resolution because they are composed only of piezo ceramics. In particular, the AE series has a rich lineup of small products, which contributes to the miniaturization of equipment and is also excellent in terms of high-speed drive and low power consumption. Regarding product lifetime and operational durability, the ASB series, ASL series, and AHB series are superior, as they feature a metal case enclosure with an airtight sealing structure. In addition, these series are also available with screws that can be fixed, for easier installation. The AHB series is suitable for applications that require large displacement, and the AE series is suitable for applications that require large generated force. The ASL series is recommended particularly for use in high-temperature environments. The AER series with its ring shape can take advantage of the space in the center of the product.
