Information

The installation kits GN 491.1 are required for the attachment of a position indicator to double tube linear actuators. They consist of an adapter shaft and, depending on the position indicator, a torque support including fixing screws.

Mechanical position indicators DD52R / DD51 / DD50 must be ordered so that the counter is aligned with the rising of the trapezoidal thread spindle.

For the position indicators DD52R-E / DD51-E the respective rising is set at the position indicator for every programming.

Accessory

Position indicators and handwheels have to be ordered separately.
