Minimum Radius of Hinged Door

• When using the safety switch for a hinged door, the minimum radius of the applica-

ble door is shown in the following figures.

Actuator Mounting Tolerance

• Mounting tolerance of the actuator is 1.0mm in the four lateral directions.

• Make sure he actuator can be inserted into the entry slot without any issue.

• When closing the door, the actuator is inserted within a certain distance from the

reference position. The contact operation is not affected by the actuator movement.

The above example are based on the condi ion 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.

HS5D Head Removal Detection Function

• The the NC contacts of the two main circuits (11-12, 21-22) are operated similarly by

the actuator. But, when the HS5D head is removed, the NC contact of the main

circuit (11-12) is opened, and other NC contact (21-22) remains closed.

• When the HS5D head is removed, the NC contact of the main circuit (11-12) is

opened, and other NC contact(s) remain closed. Use the NC contact of the main

circuit (11-12) for the safety circuit.

• Turn off he power when using this function.

CAUTION

HS9Z-A51A/HS9Z-A52A

• When there is a displacement of safety switch and actuateor, the actuator may hit the

entry slot of safety switch hardly, thus damaging the entry slot and acutuator. The

rubber cushions on the HS9Z actuator prevent the actuator from damaging the entry

slit by absorbing the shock with movement flexibility. Do not, however, exert exces-

sive shocks, otherwise the failure of safety switch may be caused.

• The rubber cushions may deteriorate depending on the operating enviroment and

conditions. Immediately replace the deformed or cracked rubber cushions with new

ones.

*1 When the torque is not enough to recommended

screw tightening torque, make sure hat the

screw do not become loose by using adhesive

sealants etc. to keep right operation and

mounting positioning.

*2 In the case of HS9Z-A51A and HS9Z-A52A,

using two M4 screws and two attached washers,

fasten the actuator securely on the door.

Adjusting the Angle Adjustable (vertical/horizontal) Actuator

(Type HS9Z-A53/A55)

• Using the angle adjustment screw (M3 hexagon socket set screw), the actuator angle

can be adjusted up to 20°(refer to dimensions).

• The larger the actuator angle, the smaller the applicable 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 adjustment screw to

prevent loosening.

(Type HS9Z-A53)

Tightening torque of angle adjustment screw : 0.8 N•m.

(Type HS9Z-A55)

Use screw locking agent that is compatible with the base material.

Base : PA66 (66 nylon) of glass reinforced grade

Angle adjustment screws : stainless steel

Actuator Mounting Reference Position

As shown below, the mounting reference position of the actuator inserted into the

safety switch is:

(Type HS9Z-A53)

The actuator stop film placed on the actuator touches the safety switch lightly.

(Except Type HS9Z-A53)

The actuator and actuator cover touches the actuator stop placed on the safety

switch lightly.

(After mounting the actuator, remove the actuator stop from the safety switch.)
