GN 491.1 installation kits 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 mounting screws.
EN 953 / EN 954 / EN 955 position indicators must be ordered so that the counter is aligned with the rising of the trapezoidal thread spindle.
For EN 9053 / EN 9054 position indicators, the respective rising is set at the position indicator for every programming.
