Product description

GN 491.1 installation kits are required for mounting a position indicator on double tube linear actuators. The kit consists of an adaptor shaft and, depending on the position indicator, a torque support including mounting screws.

When ordering EN 953 / EN 954 / EN 955 mechanical position indicators, a counter needs to be chosen that matches the pitch of the trapezoidal thread sprindle.

For EN 9053 / EN 9054 position indicators, the corresponding pitch is set on the position indicator by programming.
