Enclosed Switches
ZE/ZV/ZV2/XE/XV/XV2
CSM_ZE_ZV_ZV2_XE_XV_XV2_DS_E_2_1
General-purpose Enclosed
Switches with High Breaking
Capacity and High Durability
• Z General-purpose Basic Switches are built into ZE, ZV,
and ZV2 Switches. They provided high durability and high
breaking capacity.
• X Basic Switches with magnetic blowout are built into XE,
XV, and XV2 Switches. DC models have also been added
to the series.
• Three mounting methods (side, base, and diagonal side)
and many types of actuator are available.
• Terminals face the front when the cover is removed for
easy connection.
• Switches with ground terminals have CE marking.
• Approved by UL, CSA, and CCC (Chinese standard).
(Ask your OMRON representative for information on
approved models.)
Be sure to read Safety Precautions on page 8 to 9 and
Safety Precautions for All Limit Switches.

Note: 1. The diagonal side mounting model feature improved sealing property, improved mounting strength through use of M5 screws, increased stability in seating with
large mounting width (31 x 75 mm) and permit coupling of a number of Switch units.

Safety Precautions
Refer to Safety Precautions for All Limit Switches.
Precautions for Correct Use
Operating Environment
• Seal material may deteriorate if a Switch is used outdoor or where
subject to special cutting oils, solvents, or chemicals. Always
appraise performance under actual application conditions and set
suitable maintenance and replacement periods.
• Be sure to protect part A with grease in order to maintain the
mechanical durability and performance of the Limit Switch. The use
of molybdenum disulfide grease is recommended.
• Install Switches where they will not be directly subject to cutting
chips, dust, or dirt. The Actuator and Switch must also be protected
from the accumulation of cutting chips or sludge.
Not Suitable
Suitable
• Constantly subjecting a Switch to vibration or shock can result in
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.
• The Switches have physical contacts. Using them in environments
containing silicon gas will result in the formation of silicon oxide
(SiO2) due to arc energy. If silicon oxide accumulates on the
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.

ZE/ZV/ZV2/XE/XV/XV2
Mounting
Mounting
• With the Roller Lever-type Enclosed Switches, the roller arm has
been temporarily tightened prior to shipment, so that its position
may be adjusted later. When mounting the Switch, be sure to retighten the roller arm so as to prevent it from becoming loose during
operation.
• To adequately maintain the seals at the mounting screw section on
the side of the Enclosed Switch, insert each O-ring correctly and
secure it with the lock nut.
• To provide the Switch with improved sealing property, use of the SC
Connector is recommended. Refer to Limit Switch Connectors for
details on SC Connectors.
• When routing wires into the conduit opening, be sure that cuttings
and other foreign matter do not enter the Switch.

Operation
• Operating method, shape of cam or dog, operating frequency, and
the overtravel (OT) have significant effect on the service life and
precision of the Limit Switch. Make sure that the shape of the cam
is smooth enough.
• Check that OT has a sufficient margin. The actual OT should be
rated OT x 0.7 to 1.
Dedicated Wrench
1. The roller arm can be set freely within a range of 225° after
loosening the nut.
2. The roller arm mounting bracket can be set in any direction after
loosening the nut.
▲
• Make sure that the nut is free of foreign substances when the nut is
loosened.
• A dedicated wrench is provided separately.
