Automatic motorised brackets completely automate the process of adjusting and positioning the transmitter and receiver during tool change. During tool change, the operator can press the HOME button to drive the transmitter and receiver to the top position so punches can be removed and loaded from the ends of the machine. Once a new punch has been installed, the operator simply presses the ALIGN button and the brackets automatically drive the transmitter and receiver to the punch position until the camera receiver detects the tool tip, then Sentinel Plus automatically scans the punch and dynamically adjusts the protection zone. https://www.lazersafe.com/solutions/retrofit/sentinel-plus#automatic
