• The operation characteristics shown in the chart above are for HS9Z-A51. For other actuators, add 1.3mm.
• See page 24 for HS9Z-BA5.
• The operation characteristics show the contact status when the actuator enters the entry slot of an interlock switch.
• The contact conguration shows the status when the actuator is inserted and the switch is locked.
• Monitor Circuit: Sends monitoring signals of protective door open/closed status (door monitor) or protective door lock/unlock status
(lock monitor).
Note 1: Do not unlock manually while the solenoid is energized.
Note 2: Do not energize the solenoid for a long period of time while the door is open or while the door is unlocked manually.
Note 3: Circuit codes XF and XG do not have signals to notify whether the switch is locked or unlocked. A different method should be
used to check the lock status.
Note 4:
Both spring lock and solenoid lock models of HS5L have marking for lock monitoring. Note that solenoid lock model can be used
in applications where lock for safety purpose is found unnecessary after a risk assessment, e.g. locking is needed for purposes
such as in production process.
