Operation Indicator-equipped Models
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.
AC Operation
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 opera-
tion 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
Contact Circuit
Note: If the wiring is as shown above, the operation of the respective
parts will be as follows:
DC Operation
The DC-operated is provided with an LED indicator.
Since a rectifier stack is incorporated into the unit to permit reversing
the polarity, this type can also operate on AC power source. An exter-
nal 24VDC power supply can be used, eg. OMRON S8VS or S82K.
The LED projects from the housing for easy visibility.
When placing your order, add suffix “L2” to “L5” to the model number
of the standard type.
Example:
Standard type: ZC-Q2255
Indicator equipped type: ZC-Q2255-L2
