■ 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.

Molded Terminal Models ■ Molded Terminal Model The molded-terminal model is available with right-hand, left-hand and underside leads and is recommended for use where the Switch is exposed to dust, oil or moisture. The molded-terminal model is not approved by UL and CSA. Note: When placing your order for the Switch, specify the required length of V.C.T. cable in addition to the model number of the Switch. Example: Standard type: ZC-Q2155 Location of lead output: Underside Length of lead: 1 m (V.C.T.

Precautions ■ Correct Use Mounting Hole Dimensions 14.5+0.2 0 dia. 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.
