Safety Precautions
Refer to the “Precautions for All Switches” and “Precautions for All Safety Limit Switches”.
The Switch contacts can be used with either standard loads or
microloads. Once the contacts have been used to switch a load,
however, they cannot be used to switch smaller loads. The contact
surfaces will become rough once they have been used and contact
reliability for smaller loads may be reduced.
Mounting Method
Appropriate Tightening Torque
Tighten each of the screws to the specified torque. Loose screws may
result in malfunction of the Switch within a short time.
Electric shock may occasionally occur.
Do not use metal connectors or metal conduits.
• Do not use the Switch submerged in oil or water, or in locations
• Always attach the cover after completing wiring and before using
• Do not switch circuits for two or more standard loads (250 VAC,

result in oil or water entering the Switch interior. (The IP67 degree
of protection specification for the Switch refers to water penetration
while the Switch is submersed in water for a specified period of
time.)

holes on the bottom of the Switch, and the Switch secured at four
locations to increase the mounting strength.
Applying a load to the switch actuator (roller) on a slant may result
in deformation or damage of the actuator or rotary shaft.
