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 and adjust the stopper so that the Operation Key
is within the setting 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
continuously subject to splashes of oil or water. Doing so may
result 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.)
the Switch. Also, do not turn ON the Switch with the cover open.
Doing so may result in electric shock.

Appropriate Tightening Torque
Loose screws may result in malfunction. Tighten the screws to the
specified torques.
*1. Apply a torque of 0.78 to 0.88 N·m if the D4BS is a three-conduit
*2. Apply a torque of 4.90 to 5.88 N·m for an Allen-head bolt. For a
Mounting Dimensions (M5)
With a Three-conduit Model, the Switch can be mounted more
securely at four points rather than with just two mounting holes, i.e.,
by adding two studs at the bottom of the switch, each of which is 5 mm
maximum in height and 5
Mounting Hole Dimensions for Operation Keys
Horizontal
Mounting
Use spring washers to mount the Switch and Operation key, and
tighten the screws to a suitable torque.
To ensure safety, use screws that cannot be easily removed or
another means to prevent the Switch and Operation Key from easily
being removed.
