Rotatable connection with rotational angle limitation

A rotatable connection for a stand apparatus to be arranged in an operating room and comprising an adaptable stop mechanism which can be arranged between a first connection component and a second connection component mounted rotatably around a rotational axis relative to the first connection component and configured to define at least two different relative rotational angles of the connection components relative to the one another or at least two different rotational ranges, the adaptable stop mechanism comprising:

• a first part which can be mounted rotationally lockable on the first connection component and features at least one stop;
• a second part, which can be arranged non-rotatably on the second connection component, the first part being rotatably mounted relative to the second part;
• wherein the adaptable stop mechanism comprises a stop device having at least one counter-stop arranged axially between the two parts, wherein the at least one counter-stop corresponds to the at least one stop and wherein the stop device is configured to define the different relative rotational angles or rotational ranges by means of the at least one counter-stop.
