ML MR MD Ordering Information Note: When placing your order for the switch, specify the required length of V.S.F. or V.C.T. cable in addition to the model number of the switch. Example: Standard type: ZC-Q2155 Location of lead output: Underside Location of lead output Pre-wired terminals: COM and NO Length of lead: 1 m (V.C.T. lead) When placing your order for the above switch, specify the model number as ZC-Q2155-MD3 (VCT 1 m).

Standard length 1, 3, 5 m Operation Indicator Equipped Model 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. 6 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 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 Contact Circuit Contact Circuit NC terminal NC terminal Power source Neon lamp Power source R = 240 kΩ LED Resistance Load Load Built–in switch Built–in switch NO terminal NO terminal Power source Built–in switch Power source Built–in switch Load Load Resistance R = 240 kΩ LED Neon lamp Note: If the wiring is as shown above, the operation of the respective parts will be as follows: Contact NC NO Neon lamp Load Actuator ON Does not operate Operates OFF Operates Does not operate ON Does not operate Operates OFF Operates Does not operate Note: If the wiring is as shown above, the operation of the respective parts will be as follows: Contact NC NO Neon lamp Load Actuator ON Does not operate Operates OFF Operates Does not operate ON Does not operate Operates OFF Operates Does not operate 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. 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.
