• The contact conguration 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.
• For safety circuit input, connect to the monitor circuit.
Note 1: Actuator can be unlocked manually for conrming the door movement before wiring and energizing, and also for emergency
situation such as power failure.
Note 2: When an operator is conned within a dangerous zone, the actuator can be unlocked manually by pressing the rear unlocking
button. (rear unlocking button model)

• The operation characteristics shown in the chart above are of the 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.
