Prohibited items and notes on mounting 1. When soldering (including preheating), set the lever to the release position. 2. When soldering using a soldering iron, soldering conditions vary with the tip shape of the soldering iron, wattage, and PWB thickness. Thoroughly check the conditions in advance, including the heat resistance rating of the solder. 3. Do not apply a load to terminals when soldering. Care should be taken in this regard because a load may deteriorate electric and mechanical characteristics. 4. Since the detector switches are not sealed, do not wash them. 5. When mounting a detector switch to a through-hole type PWB, the infl uence of thermal stress on the switch is greater than that on one-sided PWB. Be sure to check the influence as well as the heat resistance rating of the solder. 6. For reflow soldering When performing reflow soldering using a hot-air oven or an infrared oven, observe the following conditions. Since the temperature applied to a switch and its terminals varies with the type and size of the PWB and the mounting density of the parts, sufficiently check the conditions in advance. Temperature (°C) 1s Peak Temperature 6 230 °C 1 Temperature rising part 2 Pre-heating part 5 Cooling part 3 4 Temperature Main heating rising part 1Temperature rising part : Ordinary temperature to Pre-heating part: 30 to 60 s. 2Pre-heating part: 150 to 180 °C, 60 to 120 s. 3Temperature rising part : Pre-heating part to 230 °C, 20 to 40 s. 4Main heating part: Rater to the figure below. 5Cooling part: Between 230 to 100 °C, 2 to 4 °C/s 6Peak Temperature: 255 °C, 1 s Time Peak temperature (°C) Notes: ● Measure temperature profile at the part surface. ● Do not perform reflow soldering more than twice. 2. If multiple switches are placed side by side, or a switch is placed near another part, the gap between the switch and the adjacent switch/part must be at least 1 mm to prevent affect of flux and to ensure proper insulation distance. 3. Design and use so that external stress is not continuously applied to the soldering parts in a set in any direction. External stress may cause pattern peeling and sol der cracks on a PWB. 4. When mounting a switch (mounting to chassis or but ton mounting), take care so that no foreign matter enters the switch. 5. Contact lubricant, which is used in detector switch es, may fl ow out to the exterior of the switch due to the struc ture. For design review, suf fi ciently check the operating conditions. 6. Avoid the following ambient surroundings and other conditions because they may affect performance: ● Under an atmosphere of corrosive gas such as Cl2, H2S, NOx, or SO2 ● In at m o sphe re s of re sidual wate r dro ps, dew condensation, or adhesive water drops ● In liquids such as water, salt solution, oil, chemicals, and organic solvents ● In direct sunlight ● In dusty locations 4. Prohibited items and notes on storage conditions Since contact characteristics and soldering quality may deteriorate due to sulfuration and oxidation of contacts and terminals, pay heed to the following items. 1. For storage and transport of the switches, avoid unpacking them, and store them at room tem perature and room humidity. Use them as soon as possible, generally within 3 months, or within a maximum of 6 months after delivery. 2. Do not store the switches under conditions of high temperature and/or high humidity, or in a location where corrosive gas may be generated. 3. If some units remain after unpacking, store them after applying adequate moisture - proof and gas - proof treatment. 5. For use in equipment for which safety is requested Specified reflow soldering condition Although care is taken to ensure switch quality, variation of contact resistance (increase), short circuits, open circuits, and temperature rise are some problems that might be generated. To design a set which places maximum emphasis on safety, review the affect of any single fault of a switch in advance and perform virtually fail-safe de sign to ensure maximum safety by: 1. preparing a protective circuit or a protective device to improve system safety, and 2. preparing a redundant circuit to improve system safety so that the single fault of a switch does not cause a dangerous situation. 230 220 210 200 0 20 40 Time (s) at 200 °C or more (Main heating part) 60 2. Notes on circuit conditions 1. To ensure reliability, use detector switches within the rated range, as designated in “Product Specifications for Information.” 2. To avoid malfunction of a set due to bounce generated by turning the switch ON and OFF, and/or due to chatter generated by external vibrations, etc., take the following into consideration in design. ● Read contact multiple times. 6. For actual use, be sure to refer to “Product Specifications for Information.” (In Case of microcomputer Processing ) ● Set a delay time. (Recommendation: 3 or more times of reading with the cycle of 3 ms or over) ● Prepare a CR integrating circuit. (Recommendation: A time constant of 6 ms or over ) 3. Prohibited items and notes on mounting and operating conditions 1. Design so that the load applied to the lever when a set is used is within the rated range of the switch's lever strength. Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
