Thumbwheel Switch A7 /C0106 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.

The Thumbwheel Switch is generally used in the configuration shown below. 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 desig- nation SEC MIN H g kg mm Symbol H J K L Q T U Stamp cm m °C PCS x 10 SEC 0 /C0083 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. 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

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. 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 de- tails) 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 -S/C0106/C0106 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-/C0106-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.

For A7MD(-D) with diode, the dielectric strength was measured at display of “0.” 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. Switch 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

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 Thumbwheel Switch Unit Terminal numbers Connector Model A7BS Dial Switch Unit or Connector Common terminal number Terminals con- nected to common Switch Unit Connector C 12 4 8 456 7 /C0083 /C0083 /C0083 /C0083 /C0083 /C0083 /C0083 /C0083 /C0083 /C0083 /C0083 /C0083 /C0083 /C0083 /C0083 The solid dot /C0083 indicates that the internal switch is ON.

Switches with Component-adding Provision To add diodes or resistors to Thumbwheel Switch circuits, use models with terminals that allocate component-adding provisions (e.g., output codes 07, 19, 55, etc.). Examples Circuit example Circuit board Application example For mounting diodes Diode Thumbwheel Switch Note: Use the terminal marked with the as- terisk * if the common terminal needs no re- sistor or diode.

Do not use where gases are generated (ammonia, chlorine, sulfur dioxide). 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 instal- lation location carefully. The A7MA is not of dust-proof construc- tion.) Provide additional dust-proofing measure when using in sand-ex- posed areas. Setting Numbers Locking Type 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 accidental- ly. Pen-push Type To set, press the setting button with a ball-point pen or other pointed object. However, avoid using pencils or mechanical pencils as bro- ken 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 plas- tic. When connecting Switches, fit the mating parts together. When separating Switches, use a screwdriver as shown in the fig- ure below; disconnect them by releasing the top and bottom hooks. Do not push the (+) and (–) operating push-buttons at the same time with undue force. Terminals for PCB Models 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 termi- nals 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. The A7MD accommodates only printed circuit boards. When pulling out the operating surface from the back of the panel, refer to the fig- ures for panel mounting dimensions. However, it cannot be fas- tened alone to the panel. 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-20/C0106-S) With the A7BS-20/C0106-S, any range can be set outside with the Stop- per Pin. Insert the Stopper Pin using the following procedure: (3) Stopper Pin (upper limit) (2) Stopper Pin (lower limit) (1) Display window 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.) 4. Confirm that the (+) push-button can no longer be pushed after reaching the upper limit of (“7”).
