ZC-@55 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.
PAGE 6
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).
