The OMRON A7PS-206 provides manual decimal selection through a push-operated mechanism. Each unit displays one digit from 0 to 9 and outputs the corresponding BCD contact pattern. Large characters make the selected value easy to check.
| Parameter | Specification |
|---|---|
| Product Type | Thumbwheel switch |
| Output Code | Binary Coded Decimal (BCD) |
| Display | Single digit, 0–9 |
| Character Height | 6.8 mm |
| Housing Color | Light gray |
| Terminals | Solder terminals |
| Mounting | Front panel, snap-in with end caps |
| Switching Capacity, Resistive Load | 1 mA–0.1 A at 50 VAC or 3.3–28 VDC |

Combine individual units to create a multi-digit setting assembly. Matching end caps secure the assembly to the panel. Sealed display windows help prevent dust entry. Connect the BCD contacts to a compatible input circuit and verify the code at each position.
Application areas include machine tools, semiconductor manufacturing equipment, and measuring instruments. Typical uses include entering cycle counts, time settings, and numerical limits into a control system.
Q1: Is the A7PS-206 a complete multi-digit assembly?
A: No. It is a single-digit switch unit.
Q2: What output does it provide?
A: A BCD contact pattern for the selected digit.
Q3: Does the display need electrical power?
A: No. The digit display is mechanical.
Q4: How is it connected electrically?
A: Through solder terminals.
