Safety Precautions
Refer to the “Precautions for All Switches” and “Precautions for All Safety Door Switches”.
■ Precautions for Safe Use
• Do not use the Switch submersed in oil or water or in locations
• Always attach the cover after completing wiring and before using
• Make sure the Switch is mounted securely to prevent it from falling
Stopper Installation
Do not use a Switch as a stopper. Be sure to install a stopper as
shown in the following illustration when mounting the Switch so that
the Operation Key is within 0.5 to 5 mm of the set zone.
Electric shock may occasionally occur.
Do not use metal connectors or metal conduits.
Injury may occasionally occur. Always check to make
sure that the safety functions operate correctly before
using the machine. The safety functions may not operate
correctly because of wiring mistakes, setting mistakes, or
Switch malfunction, causing some machines to continue
operating in situations where they should be stopped.
Injury may occasionally occur. If the machine is used with
the release key in the UNLOCK position, the
electromagnetic lock may not operate, causing some
machines to continue operating in situations where they
should be stopped. Be sure to put the release key in the
LOCK position before using the machine. Also, check the
condition of the lock and safety circuits.
Injury may occasionally occur. When the electromagnetic
lock function or Switch function is damaged, some
machines may continue operating in situations where
they should be stopped. Do not use the electromagnetic
lock function of the Switch in place of a door lock. Always
provide a lock separate from the Switch, attach a warning
seal to prevent people from using excessive force to open
the door when it is locked, or provide an indicator lamp to
show the locked/unlocked status of the door.

in oil or water entering the Switch. (The IP67 degree of protection
of the Switch specifies the amount of water penetration after the
Switch is submerged in water for a certain period of time.)

Solenoid Lock Models
The solenoid lock locks the door only when power is supplied to the
solenoid. Therefore, the door will be unlocked if the power supply to
the solenoid stops. Therefore, do not use solenoid lock models for
machines that may be operating and dangerous even after the
machine stops operating.
