Lock status can be identified from the front – Rear unlock mechanical indicator (First in the industry) (*1)
Mechanical indicator function allows the lock status to be easily identified from the front while the rear unlock mechanical indicator is
pressed.
Note: Interlock switches with rear unlock mechanical indicator function only.

Mechanical
indicator
In conventional models, because the lock
status cannot be identified from the front,
the system cannot be restarted when the
safety circuit is on. Therefore, it is necessary
to find out which safety circuit is on.
The lock status can be easily identified from the front even when the
lock is released.
Energy efficient 200mA solenoid consumption
Because the solenoid current for locking operation is 200mA,
the solenoid can be activated without using a relay.
Controller
solenoid can be
activated directly
Rear unlocking button
Door lock can be unlocked inside the barrier by a worker left
inside a hazardous area.

Spring clamp terminals
Side-conduit model
Spring clamp terminals offer excellent vibration resistance,
preventing wires from loosening. No need for additional
tightening.
Cables can be connected to the right, left, or bottom (for straight
cable orientation) of the terminal cover. Long marking tubes can
be used on the wiring cables.

*1) See page 17 regarding actuator retention force.
*2) Use 250V/10A fast-blow fuse for short-circuit protection.
*3) The actuator retention force of HS1T is 5000N at static load.
Make sure that a force exceeding the above specification is not applied.
In the event where the actuator retention force might exceed the expected load,
add a system that can detect the opening of the door and stops the machine, such
as adding another safety switch without lock (such as HS5D) or a sensor.

Additional Marking to indicate Lock Monitoring
This new international marking for lock monitoring is described in clause
9.2.1 of ISO14119 and is used to satisfy the requirements shown below.
5.7.1 General requirements
5.7.2.2 Locking monitoring
The lock monitor circuit (contacts) with this marking can monitor both the
status of protective doors and locking function. (locking monitor contact
[circuits] opens when the protective door is closed and locked)
Both HS1T spring lock and solenoid lock models have marking for lock
monitoring. Note that solenoid lock models can be used in applications where
lock for safety purpose is found unnecessary after a risk assessment, e.g.
locking is needed for purposes such as in production process.

• The contact configuration shows the status when the actuator is inserted and the switch is locked.
• Actuators are not supplied with the interlock switch and must be ordered separately.
• For safety circuit input, connect to the monitor circuit with marking.
• For side-conduit model, contact IDEC for details. (Part No: HS1T-SM-G)
• See page 9 to 12 for circuit diagrams and operating characteristics.
Note: Both spring lock and solenoid lock models have marking for lock monitoring. Note that solenoid lock models can be used in applications where lock for safety
purpose is found unnecessary after a risk assessment, e.g. locking is needed for purposes such as in production processes.

• The contact configuration shows the status when the actuator is inserted and the switch is locked.
• Monitor Circuit: Sends monitoring signals of protective door open/closed status (door monitor) or protective door lock/unlock status (lock monitor).
*1) Do not unlock manually while the solenoid is energized.
*2) Do not energize the solenoid for a long period of time while the door is open or while the door is unlocked manually.
*3) Circuit codes XF and XG do not have signals to notify whether the switch is locked or unlocked. A different method should be used to check the lock status.
*4) Both spring lock and solenoid lock models have marking for lock monitoring. Note that solenoid lock models can be used in applications where lock for safety
purpose is found unnecessary after a risk assessment, e.g. locking is needed for purposes such as in production processes.

HS1T Interlock Switches with Solenoid
Safety Precautions
• Turn power off before installation, removal, wiring, maintenance, or
inspection of the interlock switch. Otherwise electric shock or fire
may occur.
• If relays are used in the circuit between the interlock switch and
the load, use only safety relays, since welded or sticking contacts of
standard relays may invalidate the functions of the interlock switch.
Perform a risk assessment and make a safety circuit which satisfies
the requirements of the safety category.
• Do not place a PLC in the circuit between the interlock switch and the
load. Safety security can be endangered in the event of a malfunction
of the PLC.
• Do not disassemble or modify the interlock switch, otherwise
malfunction or accident may occur.
• Do not install the actuator in a location where a human body may
come into contact. Otherwise injury may occur.
• Solenoid lock is locked when energized, and unlocked when deenergized. When energization is interrupted due to wire disconnection
or other failures, the interlock switch may be unlocked causing
possible danger to the operators. Solenoid lock must not be used in
applications where locking is strictly required for safety. Perform a
risk assessment and determine whether solenoid lock is required.
• HS11T interlock switches are Type 2 low level coded interlocking
devices (ISO14119). According to EN ISO/ ISO14119, the following
is required to minimize defeat when installing and constructing
systems:
1. Prevent dismantling or de-positioning of the elements of
the interlocking device by use of non-detachable fixing (e.g.
welding, gluing, one-way screws, riveting). However, use of
non-detachable fixing can be an inappropriate solution in cases
where a failure of the interlocking device during lifetime of the
machinery can be expected and a fast change is necessary.
In this case, measures mentioned below should be used to
provide the required level of risk reduction.
2. Apply at least one out of the four measures below.
Mounting out of reach.
Physical obstruction or shielding.
Mounting in hidden position.
Integration of defeat monitoring by means of status
monitoring/cyclic testing.
Instructions
Installation
• 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/s2 may cause damage to the interlock switch.
• Install a guide on the door and make sure that force is not applied in
the direction other than the actuator entry direction.
• Do not pull the actuator during lock status. Do not use the interlock
switch as a locking device regardless of the door type. To install
a locking device, use a bracket as mentioned in page 3 of the
instruction manual.
• Make sure that the installation surface of the interlock switch is flat
and has sufficient strength to not deform when the interlock switch
is installled. Also, do not place foreign objects between the interlock
switch and the installation surface. The interlock switch may not
operate properly if the surface is not flat of a foreign object is placed
in between.
• If the operating atmosphere is contaminated, use a protective cover
to prevent 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 breakdown.
• Make sure that the actuator does not scape the entry of the metal
head. Otherwise, damage may occur.
• Install the interlock switch in a location where there is no risk of
damage.
Also, perform risk assessment before use and take measures such as
attaching a protective cover if necessary.
• While the solenoid is energized, the interlock switch temperature
rises approximately 40°C above the ambient temperature (to
approximately 95°C while the ambient temperature is 55°C). To
prevent burns, do not touch. If cables come into contact with the
interlock switch, use heat-resistant cables.
• The solenoid has polarity. Make sure of the correct polarity when
wiring. Do not apply overvoltage, otherwise the solenoid will be burnt.
• When wiring, make sure that water or oil does not enter from the end
of the cable.
18
• Use dedicated actuators only. If other actuators are used, the interlock
switch may be damaged.
• When wiring to the terminal block using a screwdriver while holding
the interlock switch in the hands, be careful not to damage fingers
with the tip of the screwdriver.
• Do not push in the screwdriver with excessive force when wiring to
the terminal block. Internal parts may crack and cause damage.
• 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.
• Safety function of the door interlock switch will be lost if a spare key
is inserted into the interlock switch. Make sure that a spare key is not
used on the interlock switch.
• Do not cut or modify the actuator. Otherwise, damage may occur.
• If multiple safety components are wired in series, the Performance
Level to EN ISO 13849-1 will be reduced due to degradation of the
failure detection function.
• Insulation of the cable should withstand environmental influences.
• The entire concept of the control system, in which the safety
component is integrated, must be validated to EN ISO 13849-2.

Instructions
Rotating the Head
Rear Unlock Button and Mechanical Indicator
• The rotating head has an allowable movement range. Do not turn the
head exceed the movement range. Otherwise, damage may occur.
• Tightening the head stopper screw withoug aligning the marks
indicated on the head and body and may cause damage
• After installing the rear unlocking button, apply thread-locking
adhesive to the screw so that the screw does not loosen.
• Make sure that foreign objects do not enter between the head and
body when rotating the head.
• Make sure to tighten the head stopper screw securely. Loose screws
may cause malfunction.
• Do not loosen the head stopper screw other than when rotating the
head.

HS1T-4
The HS1T-4 allows manual unlocking of the actuator to pre-check
proper door operation before wiring or turning power on, as well as for
emergency use such as a power failure.
Manual Unlocking Position
• Use the rear unlock button when a worker is locked inside a safety
fence (hazard area). (Compliant with escape release described in
EN ISO/ ISO 14119 [2003] and GS-ET-19)
• When the rear unlock button is pressed, the interlock switch is
unlocked and the door can be opened.
• To lock the interlock switch, pull back the button. When the button
remains pressed, the interlock switch cannot be locked even if the
door is closed, and the main circuit remains open.
• When the rear unlock button is pressed, the mechanical indicator is
displayed on the side of the interlock switch. The lock status can be
identified from outside the safety fence.
• Install the rear unlock mechanical indicator on either side of the
interlock switch.
Notes
• Install the rear unlock button inside the safety fence (hazardous area)
where only the operator is accessible. Do not install where the rear
unlock button can be reached by an operator outside the safety fence
(hazardous area). Otherwise, the interlock switch may be unlocked
during machine operation, causing danger.
• Operate the rear unlock button by hand only. Do not use a tool or with
excessive force. Do not apply force to the button from the direction
other than the proper direction, otherwise the button will be damaged.
HS1T-7Y
The solenoid interlock switch does not unlock even when the solenoid
is de-energized. However, the interlock switch can be unlocked
manually in emergency cases.
Notes
• Before manually unlocking the interlock switch, make sure that the
machine has come to a complete stop. Manual unlocking during
operation may unlock the interlock switch before the machine stops,
and the function of interlock switch with solenoid is lost.
• On solenoid lock models, do not manually unlock while the solenoid
is energized.
• Do not apply excessive force (0.45 N·m or more) to the manual
unlock key hole, otherwise the hole will be damaged.
• Do not leave the manual unlock key attached to the interlock switch
during operation. This is dangerous because the interlock switch can
be unlocked while the machine is in operation.
