4 / 5 page A7D/A7DP 4 Ordering Procedure Place orders as shown in the example below, specifying the model and number. 1. A7D-2M (End Caps): 1 pair 2. A7D-206-S @@ (Switch Unit with stopper): 1 piece 3. A7D-206 (Switch Unit): 1 piece 4. A7D-2P @ (Spacer): 1 piece 5. A7D-206 (Switch Unit): 2 pieces Note: Standard products, such as the Switch Units and End Caps, are not factory-assembled for shipment. Contact your OMRON representative for details on ordering factory-assembled sets. Safety Precautions Refer to Safety Precautions for All Thumbwheel Switches. Handling • The molded components of the Switch use polyacetal resin and PBT resin. It is recommended that alcohol is used to wipe off dirt and smudges from the molded components. Take care to prevent the alcohol from getting inside. • Do not use thinner or other solutions which might damage the resin. • Terminals can withstand a force of 4.9 N for 10 seconds or more (the mating strength of the case and seal), and survive bending of 20 ° without breaking after returning to original position. Do not use excessive force or apply repetitive external force, however, when handling terminals. In particular, take care to avoid dropping them as the terminals might bend or break. • The setting buttons can withstand 19.6 N for 1 minute, but do not push the (+) and (-) buttons at the same time. Soldering • Using a Soldering Iron Use a 30-W soldering iron at a temperature of 350 °C for a maximum of 3 seconds, and flush as described above. Do not apply force to the terminals during soldering and for 3 minutes after soldering is completed. Doing so may result in conduction or operation failure. Ensure that soldering flux and alcohol do not penetrate into the Switch interior Setting Numbers Pen-push Type Press the setting switch with the tip of a ball-point pen. Do not use pencil point or mechanical pencil point to press the setting switch, otherwise the lead of the pencil or mechanical pencil may be broken and A7DP malfunctions may result due to fragments of the broken lead. Screw-mounting Models Tighten mounting screws to a torque between 0.2 to 0.24 N·m, using M2.6 screws. Use plain washers or spring washers together with the screws. 11 4 23 5 Precautions for Correct Use |
