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 (Product code: ZC55-0003F) Suffix by Location of Lead Outlet Location of lead output Right-hand Left-hand Underside Model (Suffix) COM, NC, NO -MR -ML -MD Note: The suffixes on the left can be added to the model numbers given on page 1 to specify molded terminals.

Consult with your OMRON representative for other types of lead wires and for lead wires longer than 3 m. How to Order Example: Standard type: ZC-Q2255 Location of lead output:Right side Length of lead: 1 m (V.C.T. lead) When placing your order for the above Switch, specify the model number as ZC-Q2255-MR VCT 1M. 5 ZC-@55 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. Example: Standard type: ZC-Q2255 Indicator equipped type: ZC-Q2255-L2 Contact Circuit Power supply Neon lamp R = 240 kΩ Model Voltage rating (V) L2 L4 12 24 Leakage current (mA) Approx.2.4 Approx.1.2 Internal resistance (kΩ) 4.3 18 Contact Circuit NC terminal Power supply Load LED Built-in switch Resistor NC terminal Power supply Built-in switch Load NO terminal Load Built-in switch Power supply Neon lamp Built-in switch R = 240 kΩ Note: If the wiring is as shown above, the operation of the respective parts will be as shown in the following table.

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. 0.8 W 26 mA 100 mA 30 24 Applicable area for Microload Models (ZC-@55-01) 12 Not applicable 5 1 mA 100 mA 160 mA 0 1 0.1 10 100 1,000 Current (mA) Model Minimum applicable load ZC-@55-01 ZC-@55 5 VDC 1mA 5 VDC 160mA 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.

(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. 7 Terms and Conditions Agreement Read and understand this catalog.
