Safety Precautions
Refer to Safety Precautions for All Limit Switches.
Operating Environment
Connections
Be sure to connect a fuse with a breaking current 1.5 to 2 times the
rated current to the Limit Switch in series in order to protect the Limit
Switch from damage due to short-circuiting.
When using the Limit Switch under the EN ratings, use a gI or gG 10-
A fuse that conforms to IEC60269.
Mounting
• 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
• Secure the Switch with two M4 screws and washers.
• When mounting the panel mount-type Switch with screws on a side
• When mounting the panel mount type (SHL-Q55, SHL-Q2255, or

from the accumulation of cutting chips or sludge.
wear, which can lead to contact interference with contacts,
operation 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.

contacts, contact interference can occur. If silicon oil, silicon filling
agents, silicon cables, or other silicon products are present near the
Switch, suppress arcing with contact protective circuits (surge
killers) or remove the source of silicon gas.
The tightening torque applied to each terminal must be 1.18 to
1.37 N·m. Tighten the screws to the specified torque. An excessive
tightening torque may damage the Switch and cause a malfunction.

Micro Load Models
When using a Limit Switch for opening or closing micro-load circuit
(zones 1 through 3), contact failure may occur if a Limit Switch with
ordinary contact specifications is used. Therefore, when using Limit
Switches in the micro-load range, use ones with contact
specifications that are suited to each zone. Use the SHL-@-01 micro
load models within the zones (1 through 3) shown in the following
diagram.
Micro Load Applicable Ranges
The above diagram is for standard conditions (+5°C to +35°C, 40% to
70%RH). Since the values vary depending on the operating
environment conditions, contact your OMRON representative for
further details.

Operating Stroke
Ensure that the operating stroke for roller plunger models is within
