Hazards of the system and robot are isolated by the safety guard. When a worker needs to work inside the hazardous
area for maintenance, the worker stops the machine using the key to change modes (1), unlock the guard using the key,
then remove the key to bring inside the safety guard (2).The worker can switch operation modes and unlock the safety
guard using a single key. Furthermore, when the key is taken inside the hazardous area, the guard cannot be locked and
the system cannot be turned on. This enables the worker to work safely in the hazardous area.

Head removal detection circuitry is employed in the HS5E-K. With this innovative function, the monitor circuit (41-42) turns off
when the head is removed from the switch, such as when removing the head to change the head direction (applicable with all
models of HS5E-K).
With the head installed on the switch, monitor circuits 41-42 and 51-52 operate in synchronization while the key locks/unlocks
the actuator. When the head is removed, 41-42 turns off and 51-52 turns on. This disagreement is detected by the head removal
detection function.

Safety Precautions
•In order to avoid electric shock or fire, turn the power off
before installation, removal, wire connection, maintenance,
or inspection of the interlock switch.
•If relays are used in the circuit between the interlock
switch and the load, consider the danger and use safety
relays, since welding or sticking contacts of standard
relays may invalidate the functions of the interlock switch.
Perform a risk assessment and establish a safety circuit
that satisfies the requirement of the safety category.
•Do not place a PLC in the circuit between the interlock
switch and the load. Safety and security can be endan-
gered in the event of a malfunction of the PLC.
•Do not disassemble or modify the interlock switch, other-
wise a breakdown or an accident may occur.
•Do not install the actuator in a location where the human
body may come in contact. Otherwise injury may occur.
Instructions
•Regardless of door types, do not use the interlock switch
as a door stop. Install a mechanical door stop at the end of
the door to protect the interlock switch against excessive
force.
•Do not apply excessive shock to the interlock switch when
opening or closing the door. A shock to the interlock switch
exceeding 1,000 m/s2may cause damage to the interlock
switch.
•If the operating atmosphere is contaminated, use a pro-
tective cover to prevent the entry of foreign objects into
the interlock switch through the actuator entry slots. Entry
of foreign objects into the interlock switch may affect the
mechanism of the interlock switch and cause a break-
down.
•
Using the slot plugs supplied with the interlock switch,
plug the unused actuator entry slots.
•Do not store the interlock switches in a dusty, humid, or
organic-gas atmosphere.
•
Use proprietary actuators only. Using other actuators may
damage the interlock switch.
•Do not modify the actuator, otherwise it will damage the
interlock switch.
•Do not open the lid of the interlock switch. Loosening the
screws may damage the interlock switch.
•The actuator retention force is 1,400N. Do not apply a load
higher than the rated value. When a higher load is ex-
pected, provide an additional system consisting of another
interlock switch without lock (such as the HS5D/HS5B
interlock switch) or a sensor to detect the door opening
and stop the machine.
•Regardless of door types, do not use the interlock switch
as a door lock. Install a separate lock using a latch or take
other measures.
•Although the HS9Z-A51A and HS9Z-A52A actuators (w/
rubber bushings) alleviate the shock when the actuator en-
ters the slot on the interlock switch, make sure that exces-
sive shock is not applied. If the rubber bushings become
deformed or cracked, replace with new ones.
•Do not mount the interlock switch facing down as shown
in the figure below. Otherwise, the key may fall off due to
shock.
Incorrect Orientation
Minimum Radius of Hinged Door
When using the interlock switch for a hinged door, refer to
the minimum radius of doors shown below. For doors
with a small minimum radius, use angle adjustable
actuators (HS9Z-A53 or HS9Z-A55) .
Note: Because deviation or dislocation of a hinged door may occur in actual
applications, make sure of the correct operation before installation.

Actuator Angle Adjustment (vertical/horizontal)
•Using the angle adjustment screw, the actuator angle can
be adjusted (refer to the dimensional drawing on page 62).
Adjustable angle: 0 to 20°
•The larger the adjusted angle of the actuator, the smaller
the applicable radius of the door opening. After installing
the actuator, open the door. Then adjust the actuator so
that its edge can be inserted properly into the actuator
entry slot of the interlock switch.
•After adjusting the actuator angle, apply Loctite to the
adjustment screw so that the screw will not move.
