The FSLF actuator does not have an external stroke limiting capability. The limit of the stroke if <95 degrees would be dependent on the range of the damper it is mounted to. The actuator will drive until it reaches the full 95 degrees OR the point at which the damper has stopped moving- typical Fire and Smoke application this would be the full open position. There is built-in overload protection so once the actuator reaches a stopping point it goes into a holding mode.
