When the Operation Key is inserted, it is
locked by the lock spring. The door will stay
locked even if there is a power interruption.
If the solenoid is OFF, the door will not be
locked when the Operation Key is inserted.
This means that the door can be opened
and closed easily when replacing work-
pieces or parts.
The head can be
mounted in 3 directions.

The solenoid is released only when the
lock is turned ON.
The door is locked only when the solenoid
is turned ON. This means that the door will
be unlocked if there is a power interruption
and so this model cannot be used in sys-
tems that would maintain a hazardous
state (e.g., systems requiring toxic gases,
high temperatures, or gears that would
continue to turn due to inertia).
