This overview details the lineup of the resin exterior type prismatic AE series and ring shape AER series, with displacement on the horizontal axis and generated force on the vertical axis. The vertical axis also shows the relation between the product’s cross-section and the generated force; they are in proportion, with a generated force of about 3500 N per square cm. On the horizontal axis as well, some similar relations can be determined. The product’s length is proportional to the amount of displacement, with a displacement of approximately 10 μm for a total length of 10 mm. The smallest type is a product generating a force of 200 N and a displacement of 5 μm. This extends to a wide lineup covering up to a maximum generated force of 20,000 N, or a maximum displacement of up to 42 μm.
