Precautions Cautions Degree of Protection Do not use this product in water. lthough molded lead satisfy the test conditions for the standard given below, this test is to check the ingress of water into the switch enclosure after submerging the Switch in water for a given time. Satisfying this test condition does not mean that the Switch can be used in water. IEC Publication 529, degree of protection IP67. Do not operate the Switch when it is exposed to water spray, or when water drops adhere to the Switch surface, or during sudden temperature changes, otherwise water may intrude into the interior of the Switch due to a suction effect. Prevent the Switch from coming into contact with oil or chemicals. Otherwise, damage to or deterioration of Switch materials may result. Do not use the Switch in areas where it is exposed to silicon adhesives, oil, or grease, otherwise faulty contact may result due to the generation of silicon oxide. Terminal Connection When soldering the lead to the terminal, first insert the lead conductor through the terminal hole and then conduct soldering. Make sure that the capacity of the soldering iron is 3 W maximum. Do not take more than 3 s to solder the switch terminal. Improper soldering involving an excessively high temperature or excessive soldering time may deteriorate the characteristics of the Switch. When soldering the lead to the PCB terminal, pay careful attention so that the flux and solder liquid level does not exceed the PCB level. Side-actuated (Cam/Dog) Operation When using a cam or dog to operate the Switch, factors such as the operating speed, operating frequency, push-button indentation, and material and shape of the cam or dog will affect the durability of the Switch. Confirm performance specifications under actual operation conditions before using the Switch in applications. Correct Use Mounting Turn OFF the power supply before mounting or removing the Switch, wiring, or performing maintenance or inspection. Failure to do so may result in electric shock or burning. For M3-screw mounting, use M3 mounting screws with plane washers or spring washers to securely mount the Switch. Tighten the screws to a torque of.29 N m {3 kgf cm}. Exceeding the specified torque may result in deterioration of the sealing or damage. For with posts, secure the posts by thermal caulking or by pressing into an attached device. When pressed into an attached device, provide guides on the opposite ends of the posts to ensure that they do not fall out or rattle. Mount the Switch onto a flat surface. Mounting on an uneven surface may cause deformation of the Switch, resulting in faulty operation or damage. Operating Body Use an operating body with low frictional resistance and of a shape that will not interfere with the sealing rubber, otherwise the plunger may be damaged or the sealing may deteriorate. Handling Do not handle the Switch in a way that may cause damage to the sealing rubber. When handling the Switch, ensure that uneven pressure or, as shown in the following diagram, pressure in a direction other than the operating direction is not applied to the ctuator, otherwise the ctuator or Switch may be damaged, or the service life may be reduced. Wiring Molded Lead Wire Models When wiring molded lead, ensure that there is no weight on the or that there are no sharp bends near the parts where the is drawn out. Otherwise, damage to the Switch or deterioration in the sealing may result. Using Micro Loads Even when using micro load within the operating range, inrush currents or surges may decrease the life expectancy of the Switch. Therefore, insert a contact protection circuit where necessary. LL DIMENSIONS SHOWN RE IN MILLIMETERS. To convert millimeters into inches, multiply by.3937.
