Precautions for Correct Use Mounting LED Lamp * Always make sure that the power is turned OFF before mounting, removing, or wiring the Switch, or performing maintenance. Electric shock or fire may occur. * A current-limiting resistor for the LED lamp is built in, so no external resistor is required. Rated voltage 5 VDC 12 VDC 24 VDC Wiring * For wiring, use a wire size that is appropriate for the applied voltage and the supplied current. Be sure to perform soldering according to the following conditions. Using the Switch with incomplete soldering may result in errors and heat, which may cause fire. (1) Manual soldering: Use a soldering iron with a tip temperature of 350C maximum and complete soldering within 3 seconds. (2) Dip soldering: Solder at 350C for 3 s or less. Wait for one minute after soldering before exerting any external force on the solder. * Use non-corrosive liquid rosin as the flux. * If screw-tightened terminals are used, hold the Socket Unit Set or Socket Unit and install the lead wiring applying a torque of less than 0.98 N*m to the Socket Unit. Applying a torque of more than 0.98 N*m may result in damage. The tightening torque is 0.59 to 0.78 N*m. * Make sure that the insulating sheath of the wires does not come in contact with the Unit. If wiring is performed with the insulating sheath of the wires coming in contact with the Unit, use wire with a minimum heat resistance of 100C. * After wiring the Switch, make sure that there is a suitable isolation distance. Operating Environment Built-in limiting resistance 39 270 1300 Incandescent Lamp * It is advantageous in terms of service life and heat generation to apply 80% of the rated voltage (operating voltage) to the incandescent lamp. Operation * Always mount the Operation Unit before operating the Switch. (Using your fingers or tweezers to operate moving parts of the Switch may deform internal parts and cause malfunctions.) Character Film * If the character film is to be specially prepared, use heat-resistant film with a maximum thickness of 0.2 mm. 11.3 0.2 A3SJ A3SA 18.2 0.2 11.3 0.2 11.3 0.2 Others * If the panel is to be finished (e.g., coated), make sure that the panel meets the specified dimensions after the coating. * Do not use in locations that are subject to dust, oil, or metal fillings, because these may penetrate the interior the Switch and cause malfunction. Using Microloads Voltage (V) * Using a standard load switch when a microload circuit is opened or closed may cause wear on the contacts. Use the switch within the operating range. (Refer to the diagram below.) Even when using microload models within the operating range shown below, if inrush current occurs when the contacts are opened or closed, it may cause the contact surface to become rough, and so decrease life expectancy. Therefore, insert a contact protection circuit where necessary. The minimum applicable load is the N-level reference value. This value indicates the malfunction reference level for the reliability level of 60% ( 60) (conforming to JIS C5003). The equation 60 = 0.5 x 10-6/time indicates that the estimated malfunction rate is less than 1/2,000,000 with a reliability level of 60%. 0.15 mA 26 mA 100 mA 30 24 Standard load area Microload area 12 Invalid area 5 0 0.1 100 mA 160 mA 1 mA 1 10 100 1,000 Current (mA) 18 A3S Application Replacing Incandescent and LED Lamps and Panel Mounting Removing the Display * Grasp the groove on the color cap surface, and pull it firmly toward you to remove the Display. * An Extractor (A3PJ-5080) is available to conveniently remove the Display. Barrier Mounting * Place the Edge Barrier on the side of the Socket Unit, and then insert it into the panel. * Insert the Intermediate Barrier between the Switches after inserting the Socket Units into the panel. Intermediate Barrier Edge Barrier Mounting and Replacing Incandescent and LED Lamps Inscribing Legend Plate Characters Inscribing A3SJ (M2SJ) * Inscription depth: 0.5 mm max. * The legend plate is made of polycarbonate, so apply an alcoholbased paint coating, such as melamine, phthalate, or acrylic resin paint when marking the legend. Inserting the Display into the Socket Unit Insert the Operation Unit in the proper direction. With the OMRON logo downward, insert the Operation Unit so that the lamp/LED terminals on the inside surface of the Unit case and the contactors of the Display. Terminals for incandescent or LED lamp (built into the case) Contactors Legend plate * When replacing the legend plate, be careful that the coil spring in the Display does not become removed. OMRON logo Rated Voltage and Color of LED The LED voltage rating is indicated on the base. Use the LED within 5% of voltage range. Rated voltage Illuminating color (color band) Mounting to the Switch Panel Mount the Socket Unit to the panel by inserting it from the front of the panel. Mount the Socket Unit so that the OMRON logo is downward. 19 A3S Assembling the Legend Plate (Plunger) A3SA (M2SA) (LED Lamp) (1) Assemble the color plate to the plunger, and then assemble the legend plate on top. Legend plate Dispersion plate Plunger (Incandescent Lamp) (2) Inscribe the surface of the plunger, and then coat the surface. Lighted Square Pushbutton Switches Assemble models A3SA-5301 to A3SA-5305 so that the hook is toward you. Direction of inscription Hook toward you Note: Legend plates cannot be used with A3SA Displays for incandescent lamps. (3) Assemble the color cap to the inscribed plunger. Plunger Color cap (4) Push in the color in the direction of the arrow to assemble the plunger and the lamp holder. Lighted Square Pushbutton Switches A3SA Perform the assembly so that the wide groove and the hook on the plunger are in the same direction. Plunger Indicator M2SA Perform the assembly so that the wide groove and the hook on the plunger are in the same direction. 20 Terms and Conditions Agreement Read and understand this catalog.
