The 6528 is one of Kobelt's most robust actuators, designed to handle heavy duty positioning functions. The 6528 has additional functionality over all other Kobelt actuators with a override for manual positioning, an electro-mechanical clutch arrangement to allow for return to centre / neutral start position and a resilient driven output shaft to allow for the motor to stop and wait for balance.

The 6528 comes with a single lever that can be configured to manage a specific function. It is also available in three different springs for more torque, including a 100% spring that produces 600 in. lbs. of torque, a 75% spring that produces 450 in. lbs. and a 50% spring that produces 300 in. lbs. of torque. The 6528 also comes with a potentiometer, to provide feedback on indicators, status and more.
