In the testing application inspection using cylinder 2A, which statement is NOT true about its operation?

Cylinder 2A's operation is enhanced by external sensors for accurate functionality. The role of external sensors is crucial in various automation tasks, as they provide feedback necessary for ensuring that parts are correctly recognized and that operations are executed properly. In this case, the assertion that cylinder 2A operates without external sensors contradicts the principles of its design, especially since other statements confirm the involvement of sensors in detecting specific positions and conditions.

For instance, sensor 2B1 plays a significant role by detecting the extended end position of cylinder 2A, which is critical for the operational integrity of the inspection process. Additionally, the ability of cylinder 2A to recognize different configurations such as a lower half cube or an upper half cube depends on the proper functioning of the sensor system. These functionalities highlight that external sensors are indeed required for ensuring accurate inspection and operation, making the statement about cylinder 2A functioning independently without them untrue.
