Mounting Examples
• Install the interlock switch on the immovable machine or guard, and install the
actuator on the movable door. Do not install both interlock switch and actuator on
the
movable door, otherwise the angle of insertion of the actuator to the safety switch
may become inappropriate, and failure will occur.

• As shown below, the mounting reference position of the actuator inserted into the
safety switch is the actuator cover or stop film touches the safety switch lightly. (After
mounting the actuator, remove the actuator cover or stop film from the actuator.)
• Mounting tolerance of the actuator is 0.5mm
from the center of the actuator to up, down,
right, and, left.
• Make sure the actuator can be inserted into
the entry slot wi hout any issue.
• Actuator can move 3.3mm (HS9Z-A1S and
-A2S) / 2.6mm (HS9Z-A3S) from the mounting
reference position without affecting the contact
operation.
• When closing the door, the actuator is inserted
and locked within approx. 3.8mm (HS9Z-A1S
and -A2S) / 3.3mm (HS9Z-A3S) from the
mounting reference position.

CAUTION
*7 When the torque is not enough to recommended screw tightening torque, make
sure that the screw do not become loose by using adhesive sealants etc. to
keep right operation and mounting positioning.
*8 When rubber cushions (and spacers) are not used,
use M6 screws and tighten to a torque of 4.5 to 5.5
N•m.
Rubber Cushions
• Break a desired knockout to mount a connector using a
hammer and a screwdriver.
• Remove the connector lock nut from inside the safety
switch before breaking the knockout to open a connector
hole.
• When breaking the knockout to open a connector hole, be
careful not to damage the internal contact block.
Note : Cracks or burrs on the connector hole will degrade the
waterproof characteristics.
Opening the Connector Hole
• Using the angle adjusting screw (M3 hexagon
socket head screw), the actuator angle can be
adjusted up to 20°.
• The larger the actuator angle, the smaller the appli-
cable radius of the door swing. After installing the
actuator, open the door. Then adjust the actuator
angle so that the actuator enters the entry slot of
the safety switch properly.
• After adjusting the actuator angle, apply loctite or the like on the adjusting screw to
prevent loosening.

CAUTION
The figures shown above are based on the condition that the actuator enters and
exits the actuator entry slot smoothly when the door is closed or opened. Since
there may be deviation or dislocation of the hinged door, make sure of correct
operation in the actual application before installation.
