Rotary actuator and partial rotary actuator are divided into four series according to design. The Nano, a small driver (up to 60 Nm), forms the basis. In addition, the Nano + offers more options, a metal cover and higher torque of up to 180 Nm. The CL continues the improved version design of the drive offered prior to 2014. The Tensor precision actuator, which has abrasion-free and contactless position detection, a controlled motor and a wide-range power supply, will take driving range a long way.
