Note: 1. Use molded terminal models when using the
Switch under one of the following conditions:
a) dusty, b) high amount of dripping oil, or c)
high humidity.
2. Models are available with lead outlets in three
positions: right-hand, left-hand, and underside.

Molded Terminal Models
(Not Approved by UL, CSA, or EN)
Terminal Protective Cover, Seal Rubber, and
Rubber Packing
Use of the molded terminal model is recommended in locations
subject to excessive dust, oil drips, or moisture.
All types of ZC Switches can be fabricated into a molded terminal
version. In this case, the molded terminal model will have the same
dimensions and operating characteristics as the basic model from
which the molded terminal model is fabricated.
(The Switch is equipped with these 3 items as a
standard.)
• ZC Terminal Cover
(Product code: ZC55-0002H)
• ZC Seal Rubber
(Product code: SC-1404C)
• ZC Rubber Packing

Consult with your OMRON representative for other types of lead wires
and for lead wires longer than 3 m.

Operation Indicator-equipped Models (Not Approved by UL, CSA, or EN)
• All the models can be equipped upon request with a operation indicator to facilitate maintenance and inspection.
• Because the indicator is incorporated in the Terminal Protective Cover, the dimensions of the Limit Switch are not affected. In this model, the
lead wire is to be connected to the screw terminal. (A connecting washer is provided on the tip of the lead wire).
The lead wire can be connected to either the NC or NO terminal.
• Operating characteristics are the same as the standard model from which the operation indicator equipped model is fabricated.
(For AC)
• The operating voltage range is from 90 to 250 VAC.
• The dimensions are the same as the standard type. The top of the
Terminal Protective Cover is transparent to allow checking the
operation easily.
• When placing your order for the indicator equipped, AC-operated
model, add suffix "L" to the end of the model number.
Example:
Standard type:
ZC-Q2255
Indicator equipped type: ZC-Q2255-L
(For DC)
• The DC-operated is provided with an LED indicator.
• There is no protective structure.
• Since a rectifier stack is incorporated into the unit to permit reversing
the polarity, this type can also operate on AC power source.
• The LED projects from the housing for easy visibility.
• When placing your order, add suffix "L2" or "L4" to the model number of the standard type.

Safety Precautions
Refer to Safety Precautions for All Limit Switches.
Precautions for Correct Use
Operating Environment
Micro Load Models
Not Suitable
Suitable
Contact failure may occur is a General-purpose Switch is used to
switch a microload circuit. Use Switches within the areas shown in the
following chart. Even when using Microload Switches within the area
shown below, contact wear will become more extreme with loads that
generate surge current when switching and durability will be
adversely affected. If necessary, insert a contact protective circuit.
Microloads are indicated by N standard reference values. This value
represents the failure rate at a 60% (λ60) reliability level. (JIS C5003)
The equation λ60 = 0.5 × 10−6/operations indicates that a failure rate
of 1/2,000,000 operations can be expected at a reliability level of 60%.
DC voltage (V)
• 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.
• 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.
• 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.
Dog Angle
When operating the roller type, be sure to set the dog angle to less than
30° (even when operating at a low speed). Operating the model at a dog
angle exceeding 30° will soon cause abrasion or damage. Do not apply a
twisting force to the plunger. Set the OT to 70% to 100% of the specified
value so that the actuator will not exceed the OT.
Handling
• When detaching the Terminal
Protective Cover, insert a
screwdriver and apply a force
in the opening direction. Do
not use excess force to
remove the cover. Doing so
may cause deformation in the
fitting section and reduce the
holding force.

Mounting
• When mounting the Switch with
screws on a side surface, fasten the
Switch with M4 screws and use
washers, spring washers, etc., to
ensure secure mounting.
• When mounting the Panel Mounttype Enclosed Switch (ZC-Q55, ZCQ2255, or ZC-Q2155) with screws
on a side surface, remove the
hexagonal nuts from the actuator.
• When mounting the Terminal
Protective Cover to the case,
align the cover on the case and then press the cover down to mount
it firmly. If the cover is pressed down in an inclined position, rubber
packing will deform and thus affect the sealing capability.

• A 8.5-dia. to 10.5-dia. cable can be applied as seal rubber for the
lead wire outlet. (Use two- or three-core cable of VCT1.25 mm2.)
• Use weather-proof rubber (chloroprene rubber) as seal rubber for
the ZC-N22(21)55.
With the ZC-Q22(21)55, an
appropriate OT line is marked on
the plunger. Set the OT so that it is
between the two X-surface lines.
