They consist of an adapter shaft and, depending on the position indicator, a torque support including fixing screws. Mechanical position indicators GN 953 / GN 954 / GN 955 must be ordered so that the counter is aligned with the rising of the trapezoidal thread spindle. For the position indicators GN 9053 / GN 9054 the respective rising is set at the position indicator for every programming. see also... • Position Indicators GN 953 / GN 954 / GN 955 → Page 396 ff. • Position Indicators GN 9053 / GN 9054 → Page 402 / 404 Information • Adaptor shaft Steel Blackened • Torque support Aluminum Black anodized • ISO Fundamental Tolerances → Page 2151 • RoHS Specification • Position indicators and handwheels have to be ordered separately.
