Silicon rubber, however, can generate silicon gas. (This can occur at room temperature, but the amount of silicon gas generated increases at higher temperatures.) Silicon gas will react as a result of arc energy and form silicon oxide (SiO2). If silicon oxide accumulates on the contacts, contact interference can occur and can interfere with the device. Before using a Switch, test it under actual application conditions (including the environment and operating frequency) to confirm that no problems will occur in actual. 4 WL/WLM Selection Guide With the WL Series, OMRON will combine the switch, Actuator, and wiring method required to build the ideal switch for your application. The WL Series consists of four basic types: General-purpose, En- vironment-resistant, Spatter-prevention, and Long-life Switches. WLCA2 Switches can be used for the most common applications.

Use caution, as telegraphing (the Switch turns ON and OFF repeatedly due to inertia) may occur. 38 WL/WLM Safety Precautions Refer to Safety Precautions for All Limit Switches. Using Switches for Micro Loads Precautions for Safe Use Contact faults may occur if a Switch for a general-load is used to • When a rod or wired-type actuator is used, do not touch the top end switch a micro load circuit. Use switches in the ranges shown in the of the actuator. Doing so may result in injury. diagram below. However, even when using micro load models within (Applicable models) the operating range shown here, if inrush current occurs when the WLHAL5 and WL01HAL5 Rod Spring Levers and WLNJ-S2 and contact is opened or closed, it may increase contact wear and so WL01NJ-S2 Steel-wire Actuators. decrease durability. Therefore, insert a contact protection circuit • A short-circuit may cause damage to the Switch, so insert a circuit where necessary. The minimum applicable load is the N-level breaker fuse, of 1.5 to 2 times the rated current, in series with the reference value. This value indicates the malfunction reference level Switch. for the reliability level of 60% (λ60). –6 • In order to meet EN approval ratings, use a 10-A fuse that The equation, λ60 = 0.5 × 10 /operations indicates that the estimated corresponds to IEC60269, either a gI or gG for general-purpose malfunction rate is less than 1/2,000,000 operations with a reliability types and spatter-prevention models only. level of 60%. 5 mW 800 mW Precautions for Correct Use 0.16 mA 26 mA 30 • When wiring terminal screws, use M4 round crimp terminals and tighten screws to the recommended torque.

Current (mA) • Even when the connector is assembled and set correctly, the end of the cable and the inside of the Switch may come in contact. This can lead to malfunction, leakage current, or fire, so be sure to protect the end of the cable from splashes of oil or water and corrosive gases. 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. • 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. 39 Voltage (V) WL/WLM Built-in Switch Connectors Do not remove or replace the built-in switch.
