•The contact configuration shows the status when the actuator is inserted and the switch is locked.

•Main Circuit: Connected to the control circuit of machine drive part, sending interlock signals of the protective door.

•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 attempt manual unlocking

whenthe solenoid is energized.

Note 2: Do not energize the solenoid for a long

time while the door is open or when the

door is unlocked manually.

•The operation characteristics shown in the chart above are for HS9Z-A51.

For other actuators, add 1.3mm.

•See page 21 for HS9Z-BA5.

•The operation characteristics show the contact status when the actuator

enters the entry port of an interlock switch.
