Mounting on an uneven surface may cause deformation of the switch, resulting in faulty operation or breakage in the housing. Turn OFF the power supply before mounting or removing the switch, wiring, or performing maintenance for inspection. Failure to do so may result in electric shock or burning Operating Stroke Terminal Connection Take particular care in setting the operating stroke for the pin plunger models. Make sure that the operating stroke is 70% to 100% of the rated OT distance. Do not operate the actuator exceeding the OT distance, otherwise the life expectancy of the switch may be shortened. When soldering the lead wire to the terminal, first insert the lead wire conductor through the terminal hole and then solder. Using Microloads Voltage (V) Using a model for ordinary loads to switch microloads may result in faulty operation. Instead, use the models that are designed for microloads and that operate in the following range; Make sure that the capacity of the soldering iron is 60 W maximum. Do not take more than 5 seconds to solder the switch terminal. Improper soldering involving an excessively high temperature or excessive soldering time may deteriorate the characteristics of the switch. Be sure to apply only the minimum required amount of flux. The switch may have contact failures if flux intrudes in the interior of the switch. Use the following lead wires to connect to the solder terminals; 30 26mA 100mA 0.16mA 24 Operating range for micro load models SS-01 Operating range for general-load models SS-5, SS-10 12 Inoperable range 5 1mA 100mA 160mA Model Conductor size SS-5 0.5 to 0.75 mm2 SS-10 0.75 mm2 If the PCB terminal models are soldered in a solder bath, flux will permeate inside the switch and cause contact failure. Therefore, manually solder the PCB terminal. Wire the quick-connect terminals (#110) with receptacles. Insert the terminals straight into the receptacles. Do not impose excessive force on the terminal in the horizontal direction, otherwise the terminal may be deformed or the housing may be damaged. Insulation Distance 0 1 10 100 1,000 Current (mA) However, even when using microload models within the operating range shown above, if inrush current or inductive voltage spikes occur when the contact is opened or closed, then contact wear may increase and so decrease the service life. Therefore, insert a contact protection circuit where necessary. Use a separator between the switch and metal mounting panels, to ensure proper dielectric characteristics are achieved. According to EN61058-1, the minimum insulation thickness for this switch should be 1.1 mm and minimum clearance distance between the terminal and mounting plate should be 1.6 mm. If the insulation distance cannot be provided in the product incorporating the switch, either use a switch with insulation barrier or use a separator to ensure sufficient insulation distance.
