Enclosed Switches ZE/ZV/ZV2/XE/XV/XV2 CSM_ZE_ZV_ZV2_XE_XV_XV2_DS_E_2_1 General-purpose Enclosed Switches with High Breaking Capacity and High Durability • Z General-purpose Basic Switches are built into ZE, ZV, and ZV2 Switches. They provided high durability and high breaking capacity. • X Basic Switches with magnetic blowout are built into XE, XV, and XV2 Switches. DC models have also been added to the series. • Three mounting methods (side, base, and diagonal side) and many types of actuator are available. • Terminals face the front when the cover is removed for easy connection. • Switches with ground terminals have CE marking. • Approved by UL, CSA, and CCC (Chinese standard). (Ask your OMRON representative for information on approved models.) Be sure to read Safety Precautions on page 8 to 9 and Safety Precautions for All Limit Switches.

Precautions for Correct Use Operating Environment • 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. • Be sure to protect part A with grease in order to maintain the mechanical durability and performance of the Limit Switch. The use of molybdenum disulfide grease is recommended. • 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. Not Suitable Suitable • 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. 8 ZE/ZV/ZV2/XE/XV/XV2 Mounting Mounting • With the Roller Lever-type Enclosed Switches, the roller arm has been temporarily tightened prior to shipment, so that its position may be adjusted later. When mounting the Switch, be sure to retighten the roller arm so as to prevent it from becoming loose during operation. • To adequately maintain the seals at the mounting screw section on the side of the Enclosed Switch, insert each O-ring correctly and secure it with the lock nut. • To provide the Switch with improved sealing property, use of the SC Connector is recommended. Refer to Limit Switch Connectors for details on SC Connectors. • When routing wires into the conduit opening, be sure that cuttings and other foreign matter do not enter the Switch.

(M5 Allen-head bolt) 75±0.1 Operation • Operating method, shape of cam or dog, operating frequency, and the overtravel (OT) have significant effect on the service life and precision of the Limit Switch. Make sure that the shape of the cam is smooth enough. • Check that OT has a sufficient margin. The actual OT should be rated OT x 0.7 to 1. Dedicated Wrench 1. The roller arm can be set freely within a range of 225° after loosening the nut. 2. The roller arm mounting bracket can be set in any direction after loosening the nut. ▲ • Make sure that the nut is free of foreign substances when the nut is loosened. • A dedicated wrench is provided separately.
