How does the guard lock work?
Solenoid release: guard locks automatically when closed. Solenoid must be energized to release lock. Prevents access while machine is running.
What's the lock force?
1300N holding force. Prevents forced entry while guard is locked.
What applications require guard locking?
Machines with hazardous motion that continues after stop command (flywheel, robot, spindle). Guard must remain locked until motion stops.
