Precautions
Refer to the “Precautions for General-purpose Limit Switches (Including Multiple Limit Switches, Mechanical Touch Switches, High-precision
Switches, Touch Switches, On-site Flexible Switches; Not Including Safety Switches)” on page 17.
Operating Environment
• Seal material may deteriorate if a Switch is used outdoor or where
• Install Switches where they will not be directly subject to cutting
• Constantly subjecting a Switch to vibration or shock can result in
• The Switches have physical contacts. Using them in environments
Be sure to connect a fuse with a breaking current 1.5 to 2 times
larger than the rated current to the Switch in series in order to protect
the Switch from damage due to short-circuiting.
If the VB is used for EN ratings, use a gI or gG 10-A fuse approved
by IEC269.
Operation
Make sure the notch of the plunger is not pressed into the scraper
when operating the VB Multiple Limit Switch, otherwise chips or dust
may penetrate into the VB Multiple Limit Switch.
subject to special cutting oils, solvents, or chemicals. Always
appraise performance under actual application conditions and set
suitable maintenance and replacement periods.
chips, dust, or dirt. The Actuator and Switch must also be protected
from the accumulation of cutting chips or sludge.
wear, which can lead to contact interference with contacts, opera-
tion failure, reduced durability, and other problems. Excessive
vibration or shock can lead to false contact operation or damage.
Install Switches in locations not subject to shock and vibration and
in orientations that will not produce resonance.

Sealing
The switch box and cover are made of die-cast aluminum and the
mounting part of the Switch is covered with a seal cap, and ensure a

Limit Switch.
The filter on the side of the head prevents oil and water from pene-
trating into the interior of the VB Multiple Limit Switch while prevent-
ing the internal pressure of the VB Multiple Limit Switch from rising
when the plunger is pressed.
The seal scraper on the tip of the actuator prevents chips and dust
from penetrating into the moving parts of the VB Multiple Limit
Switch.
Apply extra tightening to the cap screw on the conduit.
In order to protect the plunger from abrasion and prolong its service
life, apply a small amount of grease to the plunger and dog or cam
that come into contact with the plunger. (Molybdenum disulfide
grease is recommended.)
