Safety Precautions
Refer to the “Precautions for All Switches” and “Precautions for All Safety Door Switches”.
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.
Do not subject the Switch to a shock that exceeds the Switch's shock
resistance of 1,000 m/s
• 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
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.

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.
