[1] Width is 78 mm when half-open; 120 mm when fully open; and 124,5 mm when fully closed with the side slides extended. [2] Speed, gripping force, and full-stroke closing time were measured with motor stiffness, damping, and torque settings across the 24–60 V range; results may vary depending on the application. [3] Form-fitting grip load is the maximum load that can be carried horizontally without losing grip and may vary depending on the application. [4] Friction grip load is the maximum vertical load that can be carried without slipping, measured with a square steel block, and may vary depending on the application. [5] Parameters may vary depending on the application and configuration. [6] Product appearance may vary; refer to the final product. The manufacturer also states that the product is for civilian use, advises avoiding hazardous modifications/methods, and requires compliance with local regulations.
