Thumbwheel Switch A7j A Wide Selection of Models: Thumbwheel- or Push-operated, Decimal or Hexadecimal A wide selection ranging from miniature models that save space to large models with enhanced readability and operability. Select models with the specifications desired, or where long life and reliability are critical. Additional new models prevent value changes due to accidental pressing of buttons. Pen-push or locking types are available.

Ordering Standard products such as the Switch Units and End Caps are not factory-assembled for shipment. Place orders as shown below, specifying the model and number of Switch Units. Ordering Example: Figure Product name Model Number of Units 1 Switch Unit A7BS-206-1 2 2 Spare Unit A7B-PA-1 1 3 Attachment Board A7B-M-1 1 set Connector A7B-CP 2 4 5 Special Characters and Symbols for Dial Displays Dials can be ordered with special characters or symbols as well as with Stoppers attached. Ask your OMRON sales representatives. 4 1: Switch Unit refers to the Switch itself. As each digit is independent of the others, a number of Switch Units are assembled to make up just the number of digits needed. 2: Spacers can be used in case the number of digits change due to a change in specifications. When units for time and length must be displayed, the necessary letters and symbols can be printed or stamped. The stamping shown in the following table can be produced. Inquire for details. Stamping Symbol A B C D E F G Stamp No designation SEC MIN H g kg mm Symbol H J K L Q T U Stamp cm m C PCS x 10 SEC 0 S Positive, Negative Dials To order dials marked with +, -, +, -, ... in place of the numerals 0 to 9, add the suffix -PM to the model number. (Refer to page 18 for details) Example: A7PS-203-PM Attaching Stoppers Stoppers are used to limit the display range from 0 to 9 down to 0 to 5, for example. Add -Sjj to the suffix, specifying the range in the blanks. Example: A7PS-203-S05 Units to which Stoppers can be attached are the A7DP, A7D, A7BL, A7PS, A7PH, A7SS, and A7AS. On the outside of the A7BS-j-S is a Stopper Pin with which the user can make any setting. The A7CN-2, A7CN-1, A7CN-L, A7MD, and A7MA cannot be equipped with Stoppers. 3, 4: End Caps/Side Plates: These are used at both ends of the Switch Unit to insure a solid mount of each Switch Unit to a panel. Left and right plates make a set. 5: Connectors: Since the Switch Unit snaps right into a Connector, accomplishing both attachment and wiring in a single action, connections, maintenance and inspection are greatly simplified. 15 A7j A7j Specifications Ratings/Characteristics Push-operated Switches Item A7DP-2/A7D-1 /A7D-2 A7CN/A7CN-L A7BL/A7BS /A7BS-20j-S A7PS A7PH Switching capacity (resistive load) 5 to 30 VDC 1 mA to 0.1 A 5 to 28 VDC 1 mA to 0.1 A 125 VAC/28 VDC 10 A to 0.15 A Continuous carry current 100 mA 1 A max. 3 A max.

Reverse-direction voltage was 35 V (min.). Operation Output Codes Output code types are distinguished according to terminal numbers on Switch Units. How to Read Output Codes Example for Output Code 06 For example, when the dial position is "3," the common terminal C on the Switch Unit is connected to terminals 1 and 2, as indicated by the solid dots in the output code table. The internal circuitry is shown below. Reference The internal circuit with diodes for the A7MD-106-P-09 is shown here, but the output condition and concepts are the same as those to the left. Diode Switch Switch 17 A7j A7j When a Switch is inserted into a Connector, e.g., for the A7BS, the common terminal C becomes connector terminal 2, and terminals 1 and 2 become connector terminals 4 and 5, respectively. 06: Binary-coded Decimal Output, Single-sided Board Model A7BS Connector Thumbwheel Switch Unit Switch Unit or Connector Switch Unit Common terminal number C 1 2 4 8 Connector 2 4 5 6 7 Terminals connected to common 0 Terminal numbers S 1 S 2 S 3 S S 4 Dial S S 5 6 S 7 S S S S S 8 S 9 S The solid dot S indicates that the internal switch is ON.

Although Switches are of nearly dust-proof construction, they are not drip-proof, therefore do not use in areas subject to water or oil exposure and do not operate with wet or oily hands. (The A7MD has a dust-proof construction on contact parts, but consider your installation location carefully. The A7MA is not of dust-proof construction.) Provide additional dust-proofing measure when using in sand-exposed areas. When using terminals for printed circuit boards, make the terminal insertion holes in the back board (mother board) 1 mm or larger in diameter. Do not use excessive force in handling terminals for printed circuit boards. In particular, take care to avoid dropping them as the terminals might bend or break. Reference: Terminals can withstand a force of 0.8 g for 1 minute or more, and survive bending of 20 without breaking after returning to original position. Setting Numbers Locking Type The A7MD accommodates only printed circuit boards. When pulling out the operating surface from the back of the panel, refer to the figures for panel mounting dimensions. However, it cannot be fastened alone to the panel. Set with the setting button by raising it. Return the button to its original position after setting. It is then locked to prevent rotation, and the set numbers will not change accidentally. Pen-push Type Connectors Insert Connectors while keeping the arrow pointing up (refer to page 31). Connector insertion load is about 1.5 kg for each A7B-C. Setting the Stopper (A7BS-20j-S) With the A7BS-20j-S, any range can be set outside with the Stopper Pin. Insert the Stopper Pin using the following procedure: (3) Stopper Pin (upper limit) (2) Stopper Pin (lower limit) (1) Display window To set, press the setting button with a ball-point pen or other pointed object. However, avoid using pencils or mechanical pencils as broken lead or lead dust may enter and damage the Switch. Handling Use alcohol to wipe off dirt and smudges from the molded-plastic cases. Take care to prevent the alcohol from getting inside. Do not use thinner or other solutions which might damage the plastic. When connecting Switches, fit the mating parts together. When separating Switches, use a screwdriver as shown in the figure below; disconnect them by releasing the top and bottom hooks. Example: To Display the Range 0 to 7 1. Any number within the range of (0 to 7) can be chosen to limit the numbers displayed in the display window. (In this example, 8 and 9 are outside of this range.) 2. First, insert the Stopper Pin in the hole in front of the lower limit ("0") for the number to be defined. 3. Next, inset the Stopper Pin in the hole past the upper limit ("7") for the number to be defined. (The Stopper Pins then surround the exact range to be defined.) Do not push the (+) and (-) operating push-buttons at the same time with undue force. 4. Confirm that the (+) push-button can no longer be pushed after reaching the upper limit of ("7"). 35 A7j A7j 5. Confirm that the (-) push-button can no longer be pushed after reaching the lower limit of ("0"). This completes the setting. For Stoppers other than those for the A7BS-20-S, refer to pages 5 to 11 of the Selection Guide as well as the ordering information on page 15. All manufactured Switches have their ranges factory-set before shipment. Soldering Note the following points when soldering printed circuit boards: Automatic Soldering After coating with flux foam 1, dip into a soldering tank 2. Thereafter, do not dip to clean. There is no danger of flux penetration in processes 1 and 2, but penetration will occur with dip cleaning, causing contact and rotational defects. Clean the flux as shown in Figure 1, tilting the Switch 45 or more and using a brush to apply the solvent only to the back of the board. It may also be cleaned by dipping only the back of the board into solvent and then using a brush to clean. Figure 1 Back of board Wipe away flux with a brush. 45 or more Dip Soldering Dip into flux solvent 1, and then into a soldering tank 2. The dipping time in process 1 is a maximum of 2 seconds. As shown in Figure 2, avoid flooding the top surface of the printed circuit board with flux. Using a brush to apply flux further reduces the danger of flux penetration. As shown in Figure 2, a brush should be used while tilting the board 45 or more. Flush flux as described above under Automatic Soldering. Figure 2 Top surface of board Using a Soldering Iron Use a 30-W soldering iron at a temperature of 350C for a maximum of 3 seconds, and flush as described above. 36
