Precautions for Safe Use Incorrect Terminal Connection Correct When soldering lead wires to the Switch, make sure that the capacity of the soldering iron is 60 W maximum. Do not take more than 5 s to solder any part of the Switch. The characteristics of the Switch will deteriorate if a soldering iron with a capacity of more than 60 W is applied to any part of the Switch for 5 s or more. • Mount a cover if the switch is to be installed in a location where worker inattention could result in incorrect operation or accidents. Operation • Make sure that the switching frequency or speed is within the specified range. 1. If the switching speed is extremely slow, the contact may not be switched smoothly, which may result in a contact failure or contact welding. 2. If the switching speed is extremely fast, switching shock may damage the Switch soon. If the switching frequency is too high, the contact may not catch up with the speed. The rated permissible switching speed and frequency indicate the switching reliability of the Switch. The life of a Switch is determined at the specified switching speed. The life varies with the switching speed and frequency even when they are within the permissible ranges. In order to determine the life of a Switch model to be applied to a particular use, it is best to conduct an appropriate durability test on some samples of the model under actual conditions. • Make sure that the actuator travel does not exceed the permissible OT position. The operating stroke must be set to 70% to 100% of the rated OT. Precautions for Correct Use Mounting Location • Do not use the switch alone in atmospheres such as flammable or explosive gases. Arcing and heat generation associated with switching may cause fires or explosions. • Switches are generally not constructed with resistance against water. Use a protective cover to prevent direct spraying if the switch is used in locations subject to splashing or spurting oil or water, dust adhering. Incorrect Terminal box Correct Terminal box • Install the switch in a location that is not directly subject to debris and dust from cutting. The actuator and the switch body must be protected from accumulated cutting debris and dirt. Incorrect Correct • Do not use the switch in locations subject to hot water (greater than 60°C) or in water vapor. • Do not use the switch outside the specified temperature and atmospheric conditions. The permissible ambient temperature depends on the model. (Refer to the specifications in this catalog.) Sudden thermal changes may cause thermal shock to distort the switch and result in faults. 146 Separate the installation location from heat sources. General-purpose Basic Switch X Correct Incorrect (preventing malfunctions) • Subjecting the switch to continuous vibration or shock may result in contact failure, faulty operation or reduced service life due to abrasion powder. Excessive vibration or shock will cause the contacts to operate malfunction or become damaged. Mount the switch in a location that is not subject to vibration or shock and in a direction that does not subject the switch to resonance. • If silver contacts are used with relatively low frequency for a long time or are used with microloads, the sulfide coating produced on the contact surface will not be broken down and contact faults will result. Use a microload switch that uses gold contacts. • Do not use the switch in atmospheres with high humidity or heat or in harmful gases, such as sulfide gas (H2S, SO2), ammonia gas (NH3), nitric acid gas (HNO3), or chlorine gas (Cl2). Doing so may impair functionality, such as with damage due to contacting faults or corrosion. • The switch includes contacts. If the switch is used in an atmosphere with silicon gas, arc energy may cause silicon oxide (SiO2) to accumulate on the contacts and result in contact failure. If there is silicon oil, silicon filling, silicon wiring, or other silicon products in the vicinity of the switch, use a contact protection circuit to limit arcing and remove the source of the silicon gas. Handling • Set the common (COM) terminal to the positive terminal. If it is set to the negative terminal, the Switch will not turn OFF. • When using the Switch under an inductive load, the arc suppression capability varies depending on current. If the current becomes 0.6 to 1.2 A or of the time constant L/R exceeds 7 ms, be sure to provide an arc suppressor. • Since the Switch incorporates a permanent magnet, attention must be paid to the following points: (a) Avoid mounting the Switch directly onto a magnetic substance. (b) Do not subject the Switch to severe shocks. (c) Avoid placing the Switch in a strong magnetic field. (d) Be sure to prevent iron dust or iron chips from adhering to the built-in magnet or the magnetic blowout function of the Switch will be adversely affected. (e) Do not apply thermal shock to the Switch, or the magnetic flux will be diminished. • Since a ventilation hole is provided to avoid abnormal corrosion due to operating conditions, provide a dustproofing device in locations where the Switch is exposed to dust. • Do not change operating positions for the actuator. Changing the position may cause malfunction. Panel-mounted Model (X-10GQ@) • To side-mount the panel-mount Switch to the panel with screws, remove the hexagonal nut from the actuator. • Too large a dog angle and too fast operating speed may damage the Switch when the Switch is side-mounted on the panel. • Too fast operating speed and too long overtravel of the roller plunger Switch may result in damage to the Switch.
